What I'm looking for

I'm looking to improve software quality through hands-on manual and automated testing, AI-assisted QA, collaborative Agile delivery, and opportunities to optimize testing processes and documentation.

At Sirocco Mobile, I coordinate testing work for web and iOS applications, combining functional, regression, exploratory, smoke, acceptance, and UX/UI testing with close collaboration across development and product teams.

I build and maintain Playwright E2E automation in Python using the Page Object Model, creating stable scenarios that increase test coverage and accelerate delivery. I also validate APIs in Postman, verify data with SQL, and investigate logs in Grafana to support root-cause analysis.

I improve QA workflows through unified Confluence documentation, Jira-based process management, and AI-assisted testing practices including prompt engineering, AI agents, MCP, CLI, GitHub Copilot, and OpenCode. I'm ISTQB Foundation Level and AI_Testers vol.1 certified.
