Over the past 4+ years, I've worked across AI, web development, blockchain, and product design, which means I can take a project from early wireframes all the way through deployment. Here's where I spend most of my time: ✅ AI & LLM Integration - RAG pipelines, custom chatbots, OpenAI/LangChain integrations, FastAPI backends for AI services. ✅ Full-Stack Development - Next.js, React, TypeScript on the frontend. Node.js, Supabase, PostgreSQL, Firebase on the backend. ✅Mobile Development - React Native for cross-platform iOS and Android apps. ✅ Blockchain & Web3 - Solidity smart contracts, Ethers.js, Web3.js, Rust. Token launches, DeFi protocols, on-chain logic. ✅ Design & UI/UX — I don't just code layouts someone else drew. I design interfaces that make sense, then build them in TailwindCSS with real attention to detail. Why Work With Me? ✔️ Proven expertise in developing applications & web platforms ✔️ Best coding practices ✔️ Fast, efficient and result driven development ✔️ Dedicated to long-term growth 📩 Let’s build!

Most developers write code. I build products. I work with founders and startups to design and ship full-stack web applications from early MVP to production-ready systems. I specialize in AI-powered apps, SaaS platforms, and blockchain integrations, handling everything from backend architecture to frontend interfaces so you get one person who owns the whole thing. I've shipped apps with 1M+ downloads, built AI-powered SaaS tools, crypto wallets, and Web3 platforms all the way to production. No handoffs, no coordination overhead, just clean systems that work.
