Chennai, India - 11:41 pm local time
Two of my live products:
haxswap com (crypto P2P exchange) and b4bwallet com (Web3 wallet) — both built from scratch and running in production today.
If you need clean code, fast delivery, and someone who takes ownership — that's exactly how I work.

Admin Dashboards & SaaS Platforms:
Data tables, analytics dashboards, role-based access, real-time updates, scalable architecture
AI Integration & Automation:
OpenAI API, Claude API, LangChain, RAG systems, AI chatbots, document Q&A platforms, workflow automation

REAL PRODUCTION EXPERIENCE
Built and deployed haxswap — a live crypto exchange with P2P trading, real-time order processing, USDT/TRC-20 support, and wallet integration.
Built b4bwallet — a production Web3 wallet with multi-chain support and secure transaction handling.
Built a full AI RAG chatbot platform — PDF/DOCX/CSV uploads, GPT-4 grounded answers, vector search using pgvector, deployed with Docker and FastAPI.
Worked on a Dubai-based crypto exchange backend — P2P trading engine, fund flow architecture, real-time transaction processing, financial-grade security.
This is production experience, not tutorial projects.
