Message

I built and own a Playwright API regression suite across 12 microservices, with 154 tests and no flakes since launch. I also created a declarative Node and Express test runner that enables non-engineers to author chained API coverage for tenant onboarding, wallets, payments, promotions, CMS, and client portals.

I've tested wallet, ledger, payment, rewards, game-client, and iGaming products across Web3 and SaaS environments. As the first QA hire at my current company, I established QA standards, test tiering, release documentation, and team onboarding while continuing to build automation for transaction integrity, authentication, API contracts, and security-sensitive public surfaces.
