At Avito, I designed Go microservices around n8n and created an MCP server for AI-assisted workflow creation. I also reduced a reviews endpoint’s p99 latency from 450 ms to 80 ms by removing N+1 queries, adding Redis read-through caching, and moving aggregate reads to a read replica.
At Yandex, I built backend services for personal data handling at up to 80k+ RPS and improved table dumping performance by replacing full-table reads with incremental reading. Earlier at Sovcombank Technologies, I rebuilt a monolithic service into independent microservices and developed services for database migration and insurance scoring.
