About

Eight years. End-to-end. Solo.

Senior fullstack engineer with 8 years building high-performance Web3, DeFi, and AI products in React/Next.js and TypeScript. Most recently delivered trading-UI features at BitMEX while solo-building and shipping a portfolio of live, revenue-generating AI products. Strong across the whole stack — front-end performance, AWS infrastructure, payments, and production LLM pipelines.

Full story →

Web3 / DeFi frontend

Built production trading UIs at BitMEX and led MonkeyDex, a Solana DEX with sub-100ms quote integration and fully on-chain copy-trading. Fluent in wallet auth, on-chain flows, and high-frequency real-time interfaces.

Senior fullstack

Takes products from architecture to live, monetized deployment alone — Next.js/React front ends on AWS (Lambda fleets, Aurora/RDS, DynamoDB, SQS), Stripe billing, and Postgres/Mongo data layers. Owns the whole stack.

AI / LLM engineering

Builds production LLM systems: autonomous content pipelines, tool-calling agents, multi-agent orchestration, citation-enforced anti-hallucination, and prompt-cost optimization (cut one pipeline ~78%).
