...indicators and oscillators, and rigorous trend analysis—so each lesson must move beyond definitions and show practical application with real-market examples. The options material should guide learners through complex spreads, volatility plays, and Greek risk management in a way that feels actionable rather than purely theoretical. Finally, the algorithmic-trading modules need code-ready logic (Python is fine), back-testing walkthroughs, and strong emphasis on risk controls. Deliverables I need from you: • A cohesive lesson-by-lesson outline for all three pillars • Fully written module content (explanations, worked examples, and short knowledge checks) • Suggested slide headings or visual cues so a designer can build accompanying decks Everything must ...

...infrastructure automation, CI/CD pipeline builds, and cloud migrations in language that resonates with both technical leads and HR screens. • Tightening the professional summary so my value proposition—speed, reliability, cost reduction—jumps off the page in the first five seconds. • Organising the skills section so the right keywords (Docker, Kubernetes, Terraform, AWS, Azure DevOps, GitLab CI, Python/Bash scripting, monitoring/observability tools) are naturally embedded without looking like a buzzword dump. • Re-structuring experience bullets into concise, metrics-oriented statements that survive automated scans and still read well to humans. • Providing the final file in an editable Word or Google Doc and a clean PDF. If you have a trac...

...responsiveness. Connection stability, automatic reconnection, and graceful handling of Bluetooth state changes are essential because the app will often run in the background. Deliverables • A self-contained React Native module (TypeScript or modern JS) that wraps all BLE operations and exports easy-to-use hooks or callbacks. • Native bridge code where needed (Swift/Objective-C for iOS, Kotlin/Java for Android) so the same JavaScript API works on both platforms. • Clear documentation and a short demo screen that prints live weight values, connection status, and battery level if the scale exposes it. • Unit tests or a simple test script proving that the module reconnects automatically after signal loss and remains within ±200 ms latency for updates...

Hi, need someone to create a python code to convert .XML file code (Datastage ) into sql query

...and datasets often. Day-to-day you’ll be: • Exploring raw data, cleaning it, and shaping robust feature sets • Designing and training predictive models and optimisation algorithms • Deploying, monitoring, and continually improving those models in production • Owning the backend APIs, batch pipelines, and any lightweight front-end hooks needed to surface the insights We work primarily in Python with TensorFlow/PyTorch, SQL, and a cloud stack (AWS + Docker/Kubernetes), though I’m open to comparable tools if you can justify the choice. Deliverables I expect: • Production-ready models that hit agreed accuracy / latency targets • Reusable, well-documented code and CI/CD pipelines • Clear weekly progress updates and a hand-off...

I already have a well-tested system prompt for Anthropic Claude and need a developer who can turn it into a straightforward public-facing website. Visual flair isn’t the priority—clarity, reliability, and a professional feel are. The core flow is simple: • Users land on Home, sign up or sign in with a classic email-and-password flow, and immediately see a clean input box to pose questions. • Claude responds in-line, covering music-theory or history queries as well as performance and practice advice. • A minimal Subscription page lets newcomers choose a plan and pay securely through Stripe, after which they gain continued access. • Logged-in users can visit their Profile to manage billing details and view their question history. React (or similar mode...

... current quiz scores, and weekly streaks; teachers or parents should be able to glance at the same data on a lightweight dashboard. Think Firebase or an equally quick cloud back-end for syncing, but I’m open to the stack you prefer as long as the data stays secure and the UI remains snappy on entry-level Android phones. Core deliverables (acceptance criteria): • Android APK + source (Kotlin or Java) compiled against the latest stable SDK • Audio-first lesson player with play / pause / seek and buffered streaming for low-bandwidth connections • Gesture-friendly interactive activities (drag-and-drop, tap to match) that tie directly to the audio content • Quiz engine supporting multiple-choice, fill-in-the-blank, and picture-based prompts, with real-...

...it has to be, but polished enough to feel professional. Core workflow • Patients open the app, review each doctor’s profile (photo, specialty, brief bio, available hours). • They pick an open slot and confirm the booking. • A push notification reminds them as the appointment approaches. That’s the heart of it. I am open to your preferred stack, yet an Android-native build in Kotlin or Java via Android Studio will likely keep things straightforward. If you already have experience wiring notifications through Firebase Cloud Messaging—or a comparable service—please mention it. Deliverables 1. Full Android source code with clear project structure. 2. Debuggable APK for testing and a signed release build. 3. Short hand-off guide ...

...BeautifulSoup. The workflow I picture is straightforward: the crawler launches on a weekly schedule, pulls the latest product information, cleans and deduplicates the results, then exports everything to either CSV and/or JSON. A quick push to a Google Sheet or an S3 bucket afterward would be ideal so the file is immediately usable by the rest of my team. Deliverables • Well-commented source code (Python preferred) • A simple scheduler set to run weekly (cron, Windows Task Scheduler, or self-contained) • Sample output file showing at least one successful pull from each target site • README with setup steps, selector notes and troubleshooting tips For acceptance, I will run the script locally, confirm the data fields match the live site, and verify ...

I will supply geometry drawings, material mix details, and the full test log once the project starts. The assignment is complete when the Abaqus model reproduces the peak load, mid-span deflection, and general crack pattern within the tolerance stated above....

The task is straightforward: I need information keyed in by hand into Excel (or, where noted, Word) exactly as it appears in the source files I will supply. Because this is pure manual data entry, there’s no data scraping, formula building, or analysis involved—just accurate transcription and consistent formatting. Accuracy is my priority, not speed, so there’s no strict deadline. I will check the first small batch to make sure we’re on the same page, then release the rest of the work. Finished files should be returned in the same layout I provide, free of typos and with any totals or page counts intact. If you enjoy methodical typing, have a good eye for detail, and are comfortable working at your own pace, this should be a simple, steady project.

Each of those tools already exposes REST/JSON APIs; the new app should push finished invoices, status updates, and relevant metadata to them in real time or near-real time. A clean, responsive web interface will let team members review, search and export invoices, and an admin panel should expose settings for branding, tax rules, triggers, and integration keys. Security (role-based access, HTTPS), solid error handling, and clear logging are essential. Deliverables • Core web app with automated invoice engine • Tested connectors for Accounting, CRM, and Inventory APIs • Documentation: setup, API endpoints, integration instructions, and a quick-start user guide The code can be in any mode...

...stream. Between songs the host should also handle quick weather and sports updates and slip in a few musical recommendations so the station always feels live and up to date. Because I’m new to AI, the first step is a short discovery chat where you explain what’s realistically possible, outline the tech stack you’d suggest—whether that’s GPT-style summarisation, ElevenLabs or similar TTS APIs, Python or Node for automation, and integration with my existing stream software—and map out ongoing hosting costs. Once we agree on the approach, I’ll need: • A script or micro-service that fetches the chosen feeds, cleans and summarises the text, generates high-quality MP3s, and queues them for broadcast. • A simple way for me to twea...

Project Description: Overview: fixed budget $50 to $70 I have a fully functional, professionally built Python-based Telegram Bot (Video demo available). I am now looking for a developer to build a Professional Web Dashboard that shares the same "brain" (Firebase Database) as the bot. The dashboard must be high-end, clean, and reflect real-time data from the bot and vice-versa. Scope of Work: Web Dashboard Development: Build a clean, professional web dashboard (Node.js or Python Flask/Django preferred). It must connect seamlessly with my existing Firebase database. Real-Time Data Sync: The bot and dashboard must be perfectly synced. If a user earns coins on the dashboard, it must instantly reflect in the Telegram bot interface. CPA Network Integr...

...The goal is to make classroom and self-study environments more inclusive, so accuracy, speed, and an intuitive user experience matter more to me than flashy extras. Here’s what I need from you: • A working real-time detection and translation engine trained specifically on ISL datasets. • Clean, well-commented code (Python + OpenCV / MediaPipe / TensorFlow or comparable libraries are fine) that I can retrain with new samples later. • A lightweight interface—desktop or web—where a learner can see their signing mirrored, along with immediate text output. • A short guide outlining model architecture, dataset sources, and steps to deploy on Windows or Linux.

Here is what I expect: • Add or correct contentDescription attributes, accessibility labels and hints so that controls are spoken in a logical order. • Ensure state changes—errors, success messages, toggles—are conveyed via accessibility events without relying on visual cues alone. • Keep visual layout untouched; all work should sit cleanly in the XML and Kotlin/Java layers. • Provide a short video or emulator capture showing TalkBack reading through a typical form flow, plus the updated source files or a merge request. If you regularly validate with TalkBack, Accessibility Scanner or Espresso accessibility tests, this will be a straightforward engagement. Let me know the Android versions you usually test aga...

...keep the video flowing in real time. • If a stream drops, the service should log the event and raise a notification; a supervising process will decide what to do next. • Frames need to be sampled at a fixed FPS that I can set per instance (e.g., 5 fps or 10 fps) and exposed through a lightweight local API so downstream AI workers can pick them up instantly. • Everything has to be written in Python with OpenCV (or GStreamer if you strongly prefer) and be easy to deploy on Ubuntu using systemd or Docker. Milestone-based delivery 1. Clean RTSP connector that plays reliably on my test Hikvision and Axis cameras. 2. Stability layer with logging + disconnection notifications. 3. Frame extractor and local API endpoint ready for integration. I will provide ca...

...need a Python solution that pulls data from a social-media platform and then runs a full analytical pass on it. The aim is to move from raw posts, likes, comments, and timestamps to clear insights I can act on. Here is exactly what the script must cover: • User engagement • Sentiment analysis • Trend analysis The flow I picture is straightforward: a scraper (or API connector, if available) gathers the latest content, saves it locally in a clean format, and hands it straight to the analysis module. Using familiar libraries—think requests/BeautifulSoup or Selenium for collection, then pandas, scikit-learn, TextBlob (or similar) plus matplotlib/Seaborn for reporting—you will deliver reproducible code that I can run from the command line.
