## Summary

Fullstack developer with 5 years of commercial experience (4 years 11 months as of mid-2026), focused on the backend (~80%) and on highload distributed systems for real-money or large-scale B2B platforms. Builds production-grade microservices on Node.js (NestJS, Fastify, Moleculer.js) and operates them on Kubernetes with a full OpenTelemetry observability stack. Comfortable across the rest of the modern web stack: React (and React Native + Expo), Vue, Next.js 15, Vike SSR, Astro for landings, TypeScript end-to-end. Integrates AI / LLM tooling and RAG pipelines into both products and engineering workflows.

Has acted as a tech lead for a small engineering team and conducts technical interviews for hiring (dozens of interviews to date). Values clear architecture without unnecessary magic, strict TypeScript with Zod contracts, integration tests that catch bugs before production, and observable systems where any UI error can be traced back to a specific gRPC call in a specific microservice.
