feat: senior frontend engineer

Frontend developer who doesn't stop at 'UI is done'. 8+ products shipped to production: from social networks to a DEX on a custom L2 Ethereum. In 2024 I built an LLM chat with MCP agents — when agentic AI wasn't yet mainstream. React/Next.js is my core, Node.js backend when needed, can read and fix Go. I know what production looks like from the inside — because I've shipped there myself.
