What I'm looking for

I’m looking to bring AI-assisted tooling into testing work. I’m available immediately for full-time work and open to remote roles.

At Infotera, I tested high-load microservice systems for Alfa-Bank and Sberbank, outstaffed via Infotera. I turned requirements into test plans and cases, ran performance, load, and stress testing, and set up test methodology for two teams.

On my open-source project madshare, I built a self-hosted media server and use Claude Code in development, with Playwright end-to-end tests and a k6 performance framework. I trace issues through logs, SQL, and Grafana dashboards, and provide developers with root-cause analysis and data to reproduce them.
