Ameer H.

I'm a senior React and Next.js developer with 5+ years of full-stack experience building production web apps, SaaS platforms, dashboards and marketplaces. I also add AI features (RAG chatbots, LLM integrations) to products that need them. You get a working, deployed app, not just a prototype. WHAT I CAN BUILD FOR YOU • React and Next.js web apps, SaaS products, admin dashboards and marketplaces (TypeScript, Tailwind CSS, Redux Toolkit) • Frontend performance work: code splitting, lazy loading, Core Web Vitals and SEO (SSR/SSG/ISR) • REST and GraphQL API integration, Stripe payments, Auth0/NextAuth authentication • AI features inside existing apps: website and document Q&A assistants with source references, chat interfaces, semantic search, summaries • Web3 front ends: wallet connection, dApps and NFT marketplaces (Wagmi, Ethers.js, WalletConnect) • Full-stack MVPs, from frontend and API to database and deployment PROOF OF WORK: WEBMIND AI WebMind AI is a live AI website assistant I built to demonstrate this stack end to end. It crawls a website, chunks the text, generates embeddings, retrieves relevant passages with semantic search, and answers questions with source references. Message me and I'll send you the live demo link. Stack: Next.js, TypeScript, Tailwind CSS, Node.js, Express.js, Supabase PostgreSQL (pgvector), Google Gemini API. (This is my own project, not a client engagement.) AI & LLM • LLM API integration (Google Gemini API and GenAI SDK) • Retrieval-Augmented Generation (RAG), embeddings, vector search • Prompt engineering and context retrieval • Adding AI functionality to existing web apps I apply existing LLM APIs to real products. I don't train models from scratch. FULL-STACK • React.js, Next.js (SSR/SSG/ISR), TypeScript, JavaScript, Tailwind CSS, Material UI • Node.js, Express.js, REST APIs, GraphQL, PostgreSQL, MongoDB • Stripe payments, Auth0/NextAuth authentication, third-party API integration • WebSockets, Jest testing, Core Web Vitals and SEO optimization HOW I WORK • Top Rated on Upwork with an 11-project track record • I scope clearly before I start, with no surprise change requests • Clean, modular code built for handoff • Full cycle: concept → build → deployment → post-launch support Have a React or Next.js project, or want an AI assistant that answers questions from your website, documents or app data? Send me a short description of your goals and I'll reply with a suggested approach and scope.
