Quero um robô que consiga antecipar, com alta precisão, o próximo resultado do jogo Aviator analisando apenas os padrões que surgem em tempo real. Não disponho de qualquer base de dados histórica, então a própria aplicação precisará coletar, processar e prever em fluxo contínuo, com latência mínima. O que considero essencial: • Captura automática dos dados diretamente da fonte do jogo (API, WebSocket ou técnica equivalente). • Módulo de análise focado em padrões ao vivo, sem depender de registros antigos. • Resposta rápida o suficiente para ser útil durante a mesma rodada. • Evidência objetiva da precisão pr...

I have a Gmail inbox that already holds a backlog of messages and will keep receiving new ones. From each email I only need six specific values that sit inside the body text—no sender info or attachments. I want an n8n workflow that: • Pulls all existing Gmail messages once, extracts those six fields, and writes them to a dedicated Google Sheet. • Keeps listening afterward so every new email is parsed and appended automatically in real time. Please build, document, and hand over the workflow file (and any helper credentials/variables clearly marked) so I can import it into my own n8n instance. The solution must run hands-free once installed, and the sheet should never duplicate rows. Feel free to propose the parsing logic—regex, HTML selectors, or another approa...

I have a sizable dataset that first needs to be cleanly extracted and then thoroughly analyzed. Because the information comes from multiple sources, I will provide a mix of Excel/CSV tables, a small hosted database dump, and several raw text exports. Your role starts with consolidating these inputs into a single, well-structured dataset, handling any duplicates or inconsistencies along the way. Once the data is tidy, I would like meaningful insights that help me understand underlying patterns. I’m especially interested in spotting emerging trends, assembling a clear, reader-friendly report, and—if the data supports it—building a simple predictive model that I can run again in the future. Please outline the statistical or machine-learning techniques you feel are most appr...

I need an automated solution that can visit Glassdoor, navigate through the public job listings I specify, and pull two fields only—Job Title and the full Job Description. The script should then write the results into a clean, comma-separated CSV file ready for downstream analysis. Key needs • Works against search terms, locations, or URLs I pass in at runtime. • Handles pagination, scrolling, and any “Show More” expansions so the entire description is captured, not just the preview. • Respects reasonable request rates or uses rotating headers/proxies so it avoids being blocked. • Runs head-less (Python + Selenium, Playwright, or similar libraries are fine) and is easy to re-run. Deliverables 1. Source code with brief setup instructions. 2. E...

I need a concise yet thorough audit of our Accounts Receivable focused exclusively on aging analysis. Your task is to extract the open A/R data from our ERP (Microsoft Dynamics 365) and produce a clear report that highlights how long each invoice has been outstanding, broken down by due-date buckets. While payment-processing and credit-risk assessments could be interesting for future phases, this engagement is limited to aging analysis only. Here is what I expect: • Cleaned A/R dataset (Excel or CSV) showing invoice date, customer ID, amount, due date, and calculated aging bucket. • A short narrative report (PDF or Word) summarising key findings—total outstanding by bucket, largest delinquent customers, and any unusual patterns you notice. • Dashboard-ready tabl...

I have a batch of PDFs—some are pure digital files, others are scanned images—and I need to pull specific text fields from each of them into a clean, well-structured Excel workbook. Because this is a one-time job, I’m aiming for the fastest reliable approach rather than an enterprise-level pipeline. Scope • Identify and capture only the targeted text values I will specify (invoice numbers, dates, totals, etc.). • Handle both searchable PDFs and image-based pages in the same run, applying accurate OCR where needed. • Output every record in an .xlsx file with clearly labeled columns ready for further analysis. Preferred Stack Python with libraries such as pdfplumber, PyPDF2, or camelot for the text-based files, combined with Tesseract (or a comparab...

Project Title: 1688 App Product Price Research (Artificial Jewellery) Project Description: We run an artificial jewellery wholesale business and are looking for a freelancer to help us find accurate product prices from the 1688 platform. We already have an Excel sheet with around 600–700 product images. Your job is simple: - Use the 1688 app (image search) to find the exact same product (not similar) - For each product, find 2–3 best price options - Choose suppliers that have good ratings and are reliable - Enter only the final prices in the Excel sheet Important Instructions: - Only exact product match is required (no similar items) - Prices should be the lowest possible but from genuine suppliers - You don’t need to provide product links, supplier names, or extra d...

I have a data scraping company and I work with music services. Basically, we collect metadata from various accounts that we generate from different countries and reconstruct current trends, genres, tempo, top artists, authors, algorithms, etc., and we sell them B2B to our clients (major record labels) like UNIVERSAL, SONY, and WARNER. We currently have a problem with Spotify; they are "killing" the accounts, and we are forced each time to generate new ones, wasting unnecessary bandwidth. We have identified that the problem occurs when using the storage credentials (auth_blob) to request the access token (bearer), which lasts 1 hour, so we need to get it often. Then they, based on the quality of the IP, take them down (but we use residential proxies, even Oxylabs, because yes, we...

I have a spreadsheet filled with raw contact information that needs to be transferred into our master format quickly and without mistakes. Your task is simple but must be done with care: copy each name, phone number, email, and any other relevant field exactly as it appears, double-checking spelling and consistency before saving. Here’s what I expect: • Clean, error-free transfer of every contact from the source spreadsheet into the designated template I’ll share. • Consistent formatting for phone numbers and emails so the list is ready for import. • A quick turnaround—once you start, I need steady progress updates until the file is complete. If you are detail-oriented, familiar with spreadsheets (Excel or Google Sheets), and can start right away, let&rsq...

I have several spreadsheets containing staff information that now need to be migrated into a cleaner, unified file. The source material is already in Excel, so you can work directly inside that environment without having to convert from paper or PDFs. For every record you will be entering three specific field groups exactly as they appear: • Name and contact details • Employment history and roles • Certifications and qualifications Consistency is critical—spelling, date formats, and credential abbreviations must match the source. A quick pass for obvious duplicates or incomplete lines before you hand the file back is also appreciated. Please send the finished workbook in .xlsx format. If you use any data-cleaning macros or Power Query steps, include them in th...

I run an ongoing project that needs a steady flow of fresh restaurant ratings completed directly on our web-based portal. After logging in through any modern browser on your laptop or smartphone, you will: • assign the star rating we specify, • leave a short, natural-sounding review (one or two sentences), and • record the confirmation details in the tiny data-capture box on the same page. Everything happens on the website—no mobile app to install—and the interface is deliberately simple. If you can follow step-by-step instructions, type a few lines of text without spelling mistakes, and keep a stable internet connection while you work, you already meet the skill requirements. I will supply: • a unique login, • a list of restaurants to rate ea...

I have a set of existing spreadsheets filled with plain text records that now need to live in clean, well-structured CSV files. Your task is to pull every row from those sheets, check that the headings stay consistent, and export the results as UTF-8 CSV without introducing any hidden characters or broken line breaks. The spreadsheets are already organised, so no deep data cleansing is required—just tidy up obvious spacing issues, preserve punctuation, and make sure every cell ends up in the correct column position in the final CSV. I will share the sheets in either Google Sheets or Excel; work in whichever environment you prefer as long as the finished deliverable is a set of ready-to-import CSV files. Deliverables • One CSV per source sheet, correctly named and enc...

I’m looking for a seasoned Python professional to step in and keep my existing codebase running smoothly. The core of the project is a collection of data-processing scripts; several of them expose lightweight endpoints through Flask, so familiarity with that micro-framework is essential. Here’s what I need from you: trace and squash the occasional bug, clean up sections that have grown messy, and tune performance when large datasets start to slow things down. I’d also appreciate guidance on best practices—whether that means introducing unit tests, improving logging, or suggesting smarter dependency management—so the project remains healthy as it evolves. You’ll work from a private Git repository, submit pull requests with clear commit messages, and pro...

I am building a cinematic blast sequence and need solid data-driven support rather than eye-balling particle emitters. The idea is to run an AI/ML simulation that predicts how metal, glass, concrete, wood and plastic fragments fly away from the detonation point, then turn those numbers into clear data-visualisation charts I can hand directly to the FX team. Scope • Direction, speed and distance must be predicted separately for each material class, following the colour code I already use on set (red = metal, blue = glass, grey = concrete, orange = wood, green = plastic). • The charts have to highlight the mean and standard deviation for every variable so the artists immediately see the “typical” trajectory as well as the natural spread. Other metrics such as perce...

I am midway through a data-heavy assignment and need a reliable pair of hands to see it through to completion. The core of the job is data organization: cleaning up the current spreadsheet, standardising formats, removing duplicates, filling obvious gaps, and ensuring every field lines up with the conventions already in place. Because this is an ongoing task, I will share both the partially organised file and a short style guide so you can match the structure and naming rules I have begun. Accuracy is critical; even small inconsistencies will ripple through later reports. I will therefore ask for a brief check-in after the first 10% so we can confirm you have the approach nailed before moving on to the rest of the file. If you also excel at report generation or document editing, ther...

I need a clean, reusable Excel workbook that lets me do two things from the same file. First, track daily attendance in a simple table that shows each employee’s name, check-in time, check-out time, and total hours worked. Second, have those attendance figures feed seamlessly into a salary-slip sheet so I can generate individual payslips at month-end without re-entering data. A formula-driven solution is my priority, but I’m open to lightweight VBA if it keeps everything one-click simple. The layout must stay fully editable, as different teams may add or hide columns later. Please deliver: • A master attendance sheet with automatic date handling and clear data-validation for time entry • Dynamic formulas (or macro) that calculate total hours per person per day and...

I have a mature ActionScript project that still runs well feature-wise, but its performance is showing its age. Right now my only priority is to squeeze every possible millisecond out of it—no new features, no general bug hunting, just measurable speed gains. Two hot spots keep holding the app back: • Loading speed, specifically during the data-processing phase after assets have been fetched. • Graphics rendering, where complex vectors and filters spike the frame time. Your task is to profile the existing code, identify the worst offenders, and refactor or rewrite sections so the initial data crunch finishes promptly and the on-screen visuals remain smooth under load. I expect you to work with typical ActionScript tooling (Flash Builder, Scout, Adobe Animate or compar...

You’ll be taking both text and numeric details that arrive in my inbox and keying them straight into a well-structured Google Sheet. Accuracy is the priority—I rely on these entries for live tracking, so every figure and word must match the original email exactly. Consistent formatting, correct placement of decimal points, and tidy column alignment are all part of the job. I’ll share the template sheet and forward the emails as they come in. Once entered, a quick cross-check against the source email before marking the row complete will keep everything spotless. Let me know your usual turnaround time per batch and any questions about the workflow, and we can get started right away. Daily 200 records to be entered this is long term project

I have a collection of Excel sheets that contain text-only fields. My goal is to consolidate, clean, and accurately re-enter this text data into a single, well-structured workbook that I will share with you at project start. The source material is already digital, so no deciphering of scans or handwriting is necessary—just meticulous copying, formatting, and validation inside Excel. Here’s what I need from you: • Transfer every text entry from the provided Excel files into the master template I supply. • Preserve spelling, punctuation, and line breaks exactly as they appear unless a clear typo is obvious, in which case flag it for confirmation. • Follow the column order and naming conventions in the template so the final workbook remains import-ready for m...

I have a dataset containing demographic details, job performance records and results from employee-engagement surveys. Your task is to turn this raw information into a reliable attrition-prediction pipeline. Work starts with careful cleaning and preprocessing: handle missing values, encode categorical variables, standardise or normalise where needed and document every step so the workflow is fully reproducible. A brief exploratory analysis should follow to highlight key attrition drivers and verify data quality before modelling. For the classifier, I’d like you to focus on K-Nearest Neighbours. If you find that another algorithm beats KNN convincingly, feel free to present the comparison—but please include KNN in the final report. Train, tune and validate the model, then eval...

I have a single CSV file that contains a mix of numerical columns and categorical labels. Before I can move on to analysis, the data needs a solid clean-up: remove or impute missing values, fix obvious data-entry anomalies, standardise text categories, and ensure each field is in the correct type. Once the dataset is tidy, I want to explore it visually. I am especially interested in bar charts, line graphs and scatter plots that help surface the main trends and relationships hidden in the numbers and categories. Feel free to suggest any additional plots that would add real insight; however, the three mentioned above are the minimum I need delivered. Python with pandas, NumPy and either Matplotlib or Seaborn is perfectly fine, but I am open to R or another proven toolset if you prefer...

I have a stack of Excel homework that is almost entirely data-entry focused and spans well over ten individual worksheets. Every sheet is already formatted; I simply need the correct figures transferred from source PDFs into the proper cells without breaking any of the existing formulas. Accuracy comes first. I will spot-check random rows, so typos or mis-aligned entries will be sent back for revision. Because there are more than ten sheets, I’d like someone who has proven experience handling large, repetitive data loads while maintaining consistency. Deliverables • All homework sheets returned in the original workbook structure, fully populated and saved in .xlsx format • A quick message summarising any anomalies you noticed (e.g., missing source values) If you have...

I have a mixed set of CT and MRI DICOM studies that need to be fully segmented in 3D Slicer. The goal is to generate clean, voxel-accurate volumetric masks I can feed directly into my AI training pipeline, so consistency across cases is critical. The dataset covers three anatomical regions—brain, chest and abdomen—and I will supply them already grouped by body part. For each series I need a single multi-label mask (or separate binary masks if that is easier for you) exported in a format 3D Slicer handles natively such as NRRD or NIfTI, together with the corresponding DICOM header preserved. Please follow these guidelines: • Use 3D Slicer’s Segment Editor tools (e.g., Threshold, Grow from Seeds, Scissors) rather than external software so the project stays repr...

I have a batch of records that sits on several publicly-accessible websites, plus a small set of well-structured PDF files. I need every field copied accurately into my online form—no spreadsheets, just direct input into the web interface I will provide. Here’s how the workflow will run: you open the source page or PDF, capture the specified data points exactly as they appear, and submit them through the form. The system validates entries in real time, so any typos or formatting issues will show up immediately. I’ll give you a quick screencast of the process along with a field-by-field guide before you start. Accuracy is top priority; speed comes second. Please be comfortable working with multiple browser tabs and following simple naming / formatting conventions. If you...
