Senior Full-Stack Engineer with 7+ years shipping production crypto, fintech, and web products end-to-end across NestJS/TypeScript APIs, React/Next.js web, and Flutter mobile. 

I own money-critical journeys across payments, webhooks, authentication, and 10+ third-party integrations; wallets, Fireblocks MPC, WalletConnect, KYC, and card/payment partners. Recent open-source work shows hands-on Go backend ownership (PostgreSQL, Kafka/event processing, Docker, CI/CD). I use LLMs, prompt engineering, RAG, evals, and AI guardrails to accelerate architecture, implementation, testing, and docs, with human review on security-sensitive paths.

Stack: Flutter/Dart, React/Next.js, TypeScript, NestJS/Node.js, Go, REST/webhooks, PostgreSQL/MongoDB/Redis, AWS, Docker.
