I am a Full Stack AI Engineer with 5 years of experience building intelligent, production-ready web apps — from AI Agents, LLM integrations and RAG pipelines to scalable API backends and clean React frontends.
I work with Python, FastAPI, LangChain, LangGraph and LLMs — OpenAI, Claude, Gemini — to ship AI features that actually work in production. Backend architecture, vector search, real-time systems and cloud deployment are my core. Frontend side covers React, Next.js and TypeScript.
Also experienced in Web3 and decentralized app development.
Clean code. Scalable systems. Real results.
FAQ
What kind of AI web applications do you build?
I build full stack AI-powered web applications — SaaS platforms, LLM chatbots, RAG systems, AI dashboards and API-heavy backends. Every project is production-ready, not a prototype. If it involves Python, FastAPI, LangChain or LLM integration, I've l
Can you integrate OpenAI, Claude or Gemini into my existing app?
Yes. I work with all major LLM providers — OpenAI, Claude, Gemini and Groq. Whether you need a chatbot, AI agent, document Q&A system or generative feature added to an existing app, I can handle the full integration including prompt

Can you handle deployment and cloud infrastructure?
Yes. I deploy on AWS, GCP, Supabase and Vercel with Docker, environment configuration and CI/CD set up. You'll receive a fully deployed, live application — not just local code.
How do you handle project communication and updates?
I share a clear scope and milestone plan before starting. You'll get regular updates at each milestone and I respond fast — usually within a few hours. No ghost mode, no surprises.
