What I'm looking for

I’m looking for a team where QA automation and API testing meaningfully improve release confidence—supporting fintech-quality standards, owning end-to-end test coverage, and collaborating closely with distributed engineering to ship stable products.

I’m a Senior Quality Assurance Engineer with strong experience delivering quality assurance across fintech, enterprise, payment, insurance, and digital banking platforms. I test web, mobile, backend, and API-driven systems using both manual and automated approaches, with a focus on improving release confidence and catching defects early.

I’ve worked on high-volume financial systems—validating complex transaction flows, coordinating cross-border deployments, and strengthening stability through functional, regression, integration, compatibility, performance, and stress testing. Alongside QA, I’m building growing backend engineering experience with Node.js, NestJS, JavaScript, and TypeScript, while also partnering with distributed engineering teams to deliver stable, scalable products.
