I’m a senior backend engineer and technical lead with 10+ years delivering scalable products. My core strengths are Node.js/TypeScript, API and microservices design, PostgreSQL and Redis, and building robust event-driven integrations. I’ve shipped LLM-assisted automation and applied RAG/agent fundamentals in production-oriented systems, with Node.js as my primary backend stack. Since 2024, I’ve integrated AI into day-to-day engineering workflows, driving in-app AI assistants for financial-services products, AI-powered co-streaming tools for Twitch, and enterprise-grade AI knowledge platform architectures. I thrive in cross-functional teams and prioritize clean architecture, observability, and measurable impact. I blend hands-on development with system design leadership to deliver resilient services and data-driven features at scale.
