I build production-grade software at the intersection of AI, fintech, and blockchain. My work spans the full stack — from backend architecture and API design to polished React frontends — with a focus on systems that handle real money, real data, and real users.

Past and current work includes an AI-powered personal health platform with food analysis and a token reward economy; and a custodial crypto trading platform integrating Cobo WaaS 2.0 for a funded fintech startup.

What I deliver for clients:

AI-integrated applications — Gemini, OpenAI, and Claude APIs wired into production products

Crypto exchange infrastructure — multi-exchange trading platform with rest API & websocket order execution, Cobo WaaS 2.0 MPC custody, KYC integration, VARA licensing support

Algorithmic trading systems — MQL4/MQL5 EAs, Python ML pipelines, live deployment on IC Markets and similar brokers

Full-stack web and desktop applications — React/Vite frontends, Node.js/Express backends, Supabase (PostgreSQL), deployed on Vercel, Railway, and AWS

Smart contracts and dApps — Solidity, Rust, Web3.js, ethers.js across EVM chains and Solana

I work independently, communicate clearly, and ship. 100% Job Success · Top Rated Plus.
