What I'm looking for

I'm looking for challenging opportunities to provide powerful backend solutions and contribute to innovative products.

At Freelance, I developed full-cycle features from clarifying requirements through production deployment, integrated LLM capabilities with attention to reliability and cost control, and added Grafana monitoring. I also improved backend performance by up to 60% and frontend performance by up to 45%.

At Midcontract, I contributed to features for a Web3-powered contract work platform and led a small Node.js team. Previously at Computools, I managed the Node.js team, planned backend and database architecture across several domains, and developed backend services.
