What I'm looking for

I'm looking to build reliable automation and quality strategy for complex web, API, database, and distributed systems, while combining hands-on testing with thoughtful AI-assisted workflows and strong human review.

I've delivered test automation and software engineering solutions for North American clients at Insight Global, Code Road, Tango Software, and TELUS International. At Total Wine & More, I design multi-framework coverage across retail UIs, APIs, SQL Server, CockroachDB, Kafka consumers, and distributed services using Python/Pytest, Playwright/TypeScript, and Postman/Newman.

I've increased automation coverage by up to 50%, reduced post-release issues by 25%, and combine automation with rigorous manual and exploratory testing. I also use GitHub Copilot and local Ollama models thoughtfully to accelerate test planning, defect investigation, and analysis while reviewing and refining every output.
