What I'm looking for

I'm looking for a role where product quality, delivery speed, and long-term productivity matter more than time spent in an office.

I've tested mobile applications, APIs, VPN services, Web3 dApps, and Telegram MiniApp integrations, with a focus on finding issues before they reach users.

At DeGuard, I managed end-to-end QA for a VPN service, combining manual and JavaScript-based automated testing. I investigated WireGuard and VLESS issues across macOS, Windows, mobile devices, and smart TVs, and worked directly with developers on API, frontend, and connectivity problems.

In my Manual QA Engineer role, I created test plans and test cases, performed regression and exploratory testing, documented defects, and collaborated with development, analytics, and project teams.

My background also includes product management and leading monitoring and technical support teams at Whoosh RU. I've recruited and mentored specialists, monitored SLA performance, contributed to Grafana dashboards, and built practical knowledge-base documentation in Confluence, Notion, and GitBook.
