- 🎯 QA Automation Engineer / SDET with 4+ years of experience: web, mobile, desktop, and API test automation
- 🎭 UI automation at scale: built 900–1200 E2E tests in TypeScript + Playwright from scratch for a cluster-virtualization platform
- 🐍 API automation: 500–700 REST / gRPC tests in Python + Pytest
- 🔧 Go: test automation in Go in my current role; previously fixed defects in a production Go backend and migrated a 500–700-test backend suite from Python + Pytest to Go; building an open-source Go reporting service
- ⚙️ CI/CD from scratch: GitLab CI & GitHub Actions, self-hosted runners, Docker-isolated runs; flaky failures driven to zero through root-cause analysis (race conditions, state isolation, timing)
- 📱 Device infrastructure: ADB orchestration of a 9+ physical Android device farm — auto-discovery, health checks, auto-recovery after reboots and hangs
- 🔎 Notable catches: a privilege-escalation defect class in an IAM/permissions system; a full-app deadlock caused by a blocking wait on an audio driver
- 👨🏫 Mentored 4–5 QA engineers: test design, framework onboarding, code review
