Acceptance Criteria 1. All listed sections present, properly formatted, and proof-read. 2. Design matches the modern/vibrant brief and prints clearly on standard US letter. 3. Hyperlinks and QR code function correctly in the PDF. If this sounds like your skill set, please share a sample of a similarly styled newsletter or brochure you’ve produced.

...route, and update support tickets until each issue is fully resolved The same experience has to be available on every touchpoint—our website, the social-media channels gathered under , and our support email—so customers never feel a hand-off when they switch platforms. Here’s what I need from you: Deliverables 1. A production-ready chatbot embedded on the website (JavaScript snippet or similar). 2. Direct integration with Instagram, Facebook, and any other social DMs housed in the Linktree above, plus our main support email inbox. 3. Clearly mapped conversation flows, fallback handling, and escalation rules to a human agent. 4. An admin dashboard where my team can edit intents, view tickets, and pull chat transcripts. 5. Brief hand-over documentat...

...mix, revenue share, and month-over-month movement without exporting anything elsewhere. Typical workflow I imagine: you receive the raw CSV from Meesho, clean or append it, reconcile against the existing master sheet, then populate the visual tabs. Everything should remain formula-driven so next month’s import is plug-and-play. If you prefer Power Query, pivot tables, or Google Sheets’ QUERY function, that’s fine—just keep the structure tidy and documented in a note. Deliverables: • Updated Excel file and matching Google Sheet with current month’s sales volume, revenue, and customer data entered and verified • In-workbook trend analysis plus pie and bar charts that auto-refresh with future data drops • Brief walkthrough (text o...

... and explore the results through dynamic, JavaScript-driven visuals. Data analysis is the heart of the job, yet I want the findings displayed in a modern web interface and, where it adds value, enhanced with lightweight 3D animations (think or similar) so patterns leap off the screen. Here is the flow I imagine: • Securely ingest CSV, JSON, or API-pulled data. • Perform statistical or exploratory analysis inside a well-structured codebase (Python on the back end or pure JS with Web Workers—open to your preferred stack). • Render interactive charts, maps, or models directly in the browser; if a 3D view clarifies insights, integrate it smoothly. • Package the whole solution in clean, documented code that I can host on a standard ...

I’m planning a new business-focused site and need a skilled web developer to guide the entire build— from wireframes to final launch. Because the site represents our corporate brand, clean code, responsive design, and a professional aesthetic are all priorities. I’m flexible on timeline; there’s no hard deadline, so you can concentrate on quality over speed. Here’s what I have in mind: • A modern, mobile-friendly front end that works flawlessly across browsers. • An intuitive back-end setup (WordPress, Drupal, or a comparable CMS—open to your recommendation) that lets my team update pages, news items, and media without touching code. • Essential pages such as Home, About, Services, News/Blog, and Contact, with room for future...

I want to launch a lightweight, static-HTML storefront that duplicates the entire catalogue—about 1,400 products—from one of my other sites. You’ll receive the source site URL plus any CSV or image assets I can export; your job is to recreate every item in the new shop. The build must rely solely on HTML, CSS and vanilla JavaScript. No CMS or database: pages should be pre-generated and fast. A simple shopping-cart script is fine as long as it can: • add / remove items, • keep totals updated, and • hand the order off to PayPal for payment. Checkout should remain guest-only; I don’t want user accounts, log-ins or saved profiles. For navigation, please group products by type so visitors can browse categories easily from the menu or sidebar....

I need a developer who can turn my personal idea into working software. Because I don’t speak English well, I’ll be communicating through an online translator, so short, clear messages—and patience—are essential. The project itself is technical: a standalone program for my own use. I’ll supply sketches, screenshots, and notes in my native language. You’ll advise on the best stack (Python, JavaScript, C#, or whatever you feel suits the goal), build the application, test it, and hand over: • Readable source code • A ready-to-run installer or executable • Simple usage instructions I can translate easily If you can add an option to switch the interface to my language, that’s a big plus. Please share a couple of small per...

I already have every design detail —HTML markup, CSS rules, JavaScript snippets, color specs, Google-Font choices, so this is purely implementation. Starting from my single-page HTML mock-up, I need the page rebuilt inside WordPress with Elementor. You’ll receive • a Word document that contains section-by-section HTML, CSS, and JS • three hi-res images for the team section • the original static HTML file for visual reference Scope of work 1. Recreate the layout in WordPress, using Elementor (or a lightweight child theme for anything Elementor can’t handle cleanly). 2. Match the dark-navy background, cyan accents, and specified Google Fonts pixel-for-pixel. 3. Make the team bios and contact email editable in the dashboard so non-dev ...

I need an existing PDF updated in two ways: first, replace the specified text exactly where indicated; second, turn the form into an “auto-sum” document. Every time any of the value fields is changed, a total must recalculate instantly. Please keep the layout, fonts, and spacing identical to the original. Use Adobe Acrobat, JavaScript, or any other reliable method you prefer as long as the final file opens in free Acrobat Reader with the calculation working flawlessly. Deliverables are the updated, fully functional PDF and the source file you edited, along with a brief note that shows me where the sum script lives so I can adjust it later if needed. A tidy, accurate result and a quick turnaround will seal the deal.

...price highlighting, and a detailed odds display that feels familiar to pro bettors yet remains uncluttered on mobile. The overall aesthetic is a modern, dark casino theme. Every screen—from desktop widescreen down to the smallest phone—needs to respond fluidly without sacrificing legibility. I’ll supply brand colours and logo; you translate them into clean, component-based HTML, CSS and vanilla JavaScript. No frameworks are mandatory, but lightweight choices (e.g. Tailwind, Alpine) are fine if they keep the codebase tidy and dependency-free. Once the exchange layout is locked, you’ll extend the same design language to the casino lobby, live-casino tables and market views, but the deliverable for this engagement is limited to frontend files only—no ...

...serve events within a configurable radius. • Give users intuitive filters: by date, by location, and by event type. • Clean, de-duplicated results returned in JSON for my existing front-end to render. Acceptance criteria 1. At least three distinct event-listing sources integrated, each returning concerts/music, sports, and community events. 2. A cron-friendly script (or equivalent cloud function) that completes a full refresh in under 5 minutes. 3. No duplicate events shown; same event from different sources must merge gracefully. 4. Endpoints documented so I can plug them into the current UI without code rewrites. 5. Clear hand-off: repo with all code, environment variables abstracted, and a short README covering setup and extension....

...browser-based railway reservation system that mirrors the core features passengers expect from large national operators. The application must let users book seats for up to six travellers under one PNR, show real-time booking status (confirmed, RAC, or waiting), handle cancellations and special-quota rules, and process secure card payments end-to-end. All functionality will be available through a responsive web interface only; native mobile apps are not in scope for this phase. The build has to respect three distinct user roles, each with its own dashboard and permissions: • Passenger • Admin • Ticket Inspector For payments I currently need seamless Credit/Debit Card integration via a PCI-compliant gateway. If future phases require Digital Wallets or Net B...

I need someone who can turn outreach into revenue for my website, mobile-app, and AI development services. Your mission is simple: find businesses with no site or an outdated one, contact them through cold email, social media messages, or a quick phone call, and walk them right through to payment. This is strictly performance-based. I release $50 the moment an invoice is paid. We’ll begin with a single-client test; nail that and we’ll roll forward together for as many clients as you can close. You should already be comfortable with lead generation and sales conversations—clear, helpful, and goal-oriented. I handle project scoping and delivery; you focus on getting the deal across the line. Deliverable • One fully paying client (contact details plus proof of paym...

...VBA-driven GUI. I now need the same experience available through a browser so colleagues can access it without downloading the file. The workbook is fairly simple: a user enters 2 parameters into input boxes, presses a "calculate" button, and some straightforward calculations are run, to output 2 sets of results from the calculations. Key requirements • Technology: please build it with JavaScript. I am open to the specific stack—plain JS, React, Vue, Svelte, or similar—but the finished code must run in any modern browser and be easy to host on a standard Linux server (Node.js or static + serverless functions are both fine). • Functionality to replicate: – Data-input forms that mirror the existing Excel userforms. – All u...

...PDFs, DOC/DOCX or ZIPs, with a configurable max-size limit and server-side validation. • Basic comforts: online/offline badge, typing indicator, unread counter and email or push notification when the other party is away. Technical fit My back end is PHP (Laravel), so I need clear hooks, API endpoints or events I can drop straight in. Keep the front-end code framework-agnostic or in vanilla JavaScript if possible; if you need React or Vue, please isolate it in its own component folder. Deliverables 1. Fully commented source code (front end and back end) 2. Database migration or schema update script 3. Configuration notes for any third-party service keys 4. Quick-start setup guide and API documentation 5. Two-week bug-fix and hand-holding window after delivery ...

...Netlify serverless function that sits in front of the Anthropic Claude endpoint. Validate each request with the Supabase-issued JWT and block anything that fails or exceeds rate limits. Return usage metrics so I can log prompt counts per user. AI Prompt Stability The letter-generation system prompt (approximately 5KB) currently lives inside alongside the UI code. Every time a developer touches the frontend there is a risk the prompt is accidentally changed or corrupted. This has happened repeatedly during development and each time it degrades the quality of compliance letters going to FCA-regulated advisers. Extract the prompt function from into a dedicated server-side file inside the Netlify function (e.g. netlify/functions/prompts/). The function must acc...
