QA Automation
Playwright, Cypress, Pytest — end-to-end coverage.
Portfolio · 2026
Hi, I'm Malachy. QA Engineer, System Admin & IT Support Specialist.
I engineer confidence into software and infrastructure — from automated test suites to resilient servers, with a fondness for LLM-driven, spec-first workflows.
About
Engineering quality, from code to server rack.
I'm Malachy — a QA engineer and systems specialist who treats software the way an architect treats a building. Every deploy, every migration, every test suite is a chance to make things feel effortless for the humans that come after.
I lean on Playwright, Docker, and Linux daily, and I've been deeply exploring LLM-driven, spec-first coding — where the conversation between engineer and model becomes the source of truth.
