I’m a Backend Developer focused on building reliable services in Go, from architecture through delivery. I’ve worked on B2B systems where correctness and operational stability are essential.

At Yandex, I designed the architecture of a B2B credit issuance service for merchants and implemented the full credit lifecycle: creation, activation, payment schedule, partial and early repayment. I also built APIs handling 20–30k requests per day with integration into billing systems.

I optimize for performance and resilience: I improved key endpoints by 10–15% through SQL query and data structure optimization. I implemented event-driven communication via Kafka (50–100k events per day), added observability with metrics/alerts/dashboards, participated in incident analysis, and covered critical logic with tests to reduce regressions.

Before that, at Neofamily, I refactored legacy logic, implemented integrations with external APIs (timeouts, retries, and errors), and helped develop a backend service handling up to 5–10k requests per day. I also automated configuration and environment variable management and strengthened production diagnostics with basic observability, while using unit and functional tests.
