I am a hands-on automation and developer productivity engineer with 9+ years of experience in QA automation, test framework development, CI/CD workflows, and internal tooling.I build practical systems that improve test coverage, reduce repetitive work, and help engineering teams deliver software with more confidence.My background includes C#, Python, TypeScript, Selenium, Playwright, n8n, APIs, webhooks, GitHub, Bitbucket, Jira, Confluence, and CI/CD pipelines.I also build personal 2D game projects using C# and MonoGame, which keeps me close to hands-on software development, debugging, planning, and product thinking.

QA Automation Lead & SDETI build AI-powered automation — and I'm the engineer who can prove it works.Nine years building test automation from scratch: Playwright, Selenium, C#/.NET, TypeScript, Python, wired into CI/CD at four companies. Cut regression testing time by 80%. Built frameworks where there were none.For the last two years I've built production LLM and agent workflows — n8n orchestrating REST APIs, webhooks, and language models on a Linux server I run myself. Error handling, retries, monitoring — the parts that break at 2am. That work removed 300+ hours of manual effort per month.Most teams shipping AI agents in 2026 have no idea how to test them. Non-deterministic output, no stable assertions, no coverage model. I've spent nine years on coverage, risk, and evidence — and two years building the AI systems themselves. I do both halves.WHAT I DO
→ AI & agent testing — LLM output evaluation, eval harnesses, non-deterministic test strategy
→ Workflow automation — n8n, APIs, webhooks, self-hosted Docker
→ Test frameworks — Playwright, Selenium, C#, TypeScript, Python
→ CI/CD — GitHub Actions, Bitbucket Pipelines
→ Test strategy — ISTQB Advanced Test Manager & Test AnalystAvailable now for remote contract and full-time work, worldwide.Get in Touch
