Backend architecture
Node.js, TypeScript, Express.js, TRPC, event-driven systems, Redis, RabbitMQ, WebSockets, MongoDB, PostgreSQL, and high-availability microservices.
Tech Lead / Fullstack Developer
Scalable web platforms from architecture to production.
I am a fullstack developer with 8+ years of experience specializing in Node.js, Vue.js, TypeScript, cloud infrastructure, microservices, and high-traffic products. I design architecture, lead teams, mentor engineers, and deliver production-ready systems.
