Andrii Hakman

I’m a Middle QA Engineer with 3+ years of commercial experience testing web and mobile applications. I focus on functional, regression, smoke, integration, exploratory, API, and database testing, with strong ownership of quality from requirements to release.

I work end-to-end with requirements analysis, test documentation, release validation, and defect lifecycle management. My daily toolkit includes Postman and Swagger for REST API validation, Charles Proxy and Chrome DevTools for investigations, and SQL with PostgreSQL/MySQL/MongoDB to confirm data correctness.

At PEIKO, I performed functional, regression, smoke, integration, API, and database testing for web and mobile products, validated REST APIs, and supported release validation and production verification in Agile/Scrum collaboration. Previously at BOOSTY and JMX, I tested user flows and web/mobile features, reported clear defects, verified data consistency between frontend and backend, and participated in sprint planning and release support.
