What I'm looking for

Remote full-time role in QA automation for backend systems, Go or Python. Happy to start automation from scratch or grow an existing framework, including CI, reporting and load testing. Russian-speaking teams are a plus.

Most of my QA career has been backend test automation: Go or Python against gRPC and REST APIs, with Kafka, ClickHouse and PostgreSQL behind them. On two projects (Ozon, then MTS) I was the one who started test automation from zero: first tests, GitLab CI pipelines, Allure TestOps, load testing of bidirectional gRPC streams. Since 2025 I've also been testing LLM-based products.

Most of my background is security software (SIEM, a deception platform, VPN clients), plus a year in telecom. I've interviewed QA candidates, mentored juniors and helped manual testers move into automation.

Based in Moscow (UTC+3), working remotely. English B1: I read documentation and write tickets in English without trouble.
