I need a clean, modern, minimalist frontend that guides mobile users through four key moments: logging in, opening the phone camera from the browser, sending each capture to my backend for both OCR and AI image recognition, and finally displaying a running points balance that can be exchanged in a small reward catalogue. The project is strictly front-end: I will expose REST/GraphQL endpoints for authentication, image upload/analysis, point bookkeeping and catalogue data. You wire the UI, handle state, and ensure a smooth hand-off of images taken with the mobile camera (desktop fallback is a plus but not essential). Feel free to recommend the stack—React + , Vue 3, or a similarly lightweight SPA framework are all acceptable as long as it stays performant on mobile. Core deliv...

Hey! I’m looking to hire an experienced developer to build a universal product-detail scraping pipeline that takes a product URL (any website) and returns a complete structured product record. This is not a “simple HTML parse.” Many target sites are React/Next/Vue, load content via XHR/GraphQL, hide details behind tabs/accordions/modals, and lazy-load images/PDFs. The solution needs to reliably extract everything a human can see on the page, plus the underlying data used to render it. What the scraper must do (high level) Given a product URL, the pipeline should: Load the page like a real user (handle cookies/overlays). Capture all content from multiple sources (DOM + network + interactions). Use GPT API strategically to increase accuracy (field mapping, vari...

Key requirements • Design language: Modern, with subtle hover effects, fluid scroll animations, and context-aware modal pop-ups that enhance—not distract from—workflows. • Responsiveness: Fully optimized for desktop and mobile; tablet support is welcome but not essential right now. • API readiness: Develop against mocked data today, but structure the code so I can drop in the real REST/GraphQL endpoints the moment the UI is approved. I will supply the exact API specs at that stage. • Technology hygiene: Modular components, semantic HTML5, accessible styling (preferably using CSS-in-JS or modern utility classes), and clear documentation that lets another developer pick up the repo without guesswork.
