What I'm looking for

I’m looking for a QA role where I can own end-to-end testing, validate APIs and mobile flows, run performance checks, and participate in release risk/go-no-go decisions with cross-functional teams.

I’m a QA Engineer with 5 years of manual-first testing experience across web, mobile (Android/iOS), and backend systems. I build and maintain testing processes from scratch—covering functional, integration, smoke, regression, system, and API testing.

I’ve worked across FinTech, CRM, SaaS, and Telegram-based products, validating business logic and data using SQL and databases like PostgreSQL. I also participate in release cycles, including risk assessment and go/no-go decisions, to keep product quality consistent across the full development lifecycle.

In my roles, I’ve prevented more than 100 blocking and over 165 critical defects from reaching production, and improved performance by 40% through load testing. I’ve implemented Android UI automation, performed load testing with k6 and Locust (and JMeter), and managed a QA team of 2–3 engineers while improving QA/DEV synchronization and documentation.
