About
Built for teams that value credibility over ceremony.
I help product and engineering teams raise release confidence through structured QA systems, robust automation, web development, and a clear quality culture. My background spans central banking, fintech, blockchain, logistics, luxury digital, hospitality, and consumer-facing apps.
The work is not just writing test cases. It is defining the right quality model, building durable tooling, tightening delivery loops, and making quality measurable at the product level.
Playwright, CI pipelines, API validation, and maintainable release coverage.
Quality decisions grounded in risk, customer impact, and delivery speed.
