What I'm looking for

I’m looking for a QA leadership role where I can own quality for mobile products end-to-end—test strategy, releases, and analytics validation—while mentoring teams and improving QA workflows to reduce release risk.

I’m a Senior QA Engineer with 10+ years of experience testing mobile, web, CRM, and backend applications across FinTech, AI, Gaming, CRM, and SaaS. I’ve contributed to the successful delivery of 20+ mobile applications and 40+ web platforms, building quality into the full release lifecycle—from requirements analysis and test strategy to production verification and post-release monitoring.

My work is hands-on and end-to-end: I validate complex business logic, financial workflows, payment systems, subscriptions, and third-party integrations using REST API testing, backend validation, and analytics verification. I’ve built QA processes, testing environments, and documentation from scratch, introducing testing standards, release procedures, and regression suites to help teams ship reliably.

I also help teams scale quality through mentoring and leadership. I’ve led QA activities across multiple concurrent mobile applications, conducted 40+ technical interviews, and collaborated closely with Product Managers, Developers, Designers, Analysts, and business stakeholders—while staying focused on dependable releases and practical QA automation with tools like Cursor and MobileNextMCP.
