At Wildberries (WB), I develop Go microservices for a corporate platform managing premises, HR requests, and approval workflows. I implemented gRPC/HTTP APIs, Kafka-based office data synchronization, and request-stage operations with concurrent state updates in PostgreSQL.

At BI.ZONE, I developed Go microservices for processing and analyzing security logs, including Kafka pipelines and integrations with an incident monitoring system. I also conducted load testing of log-processing services.
