Aleksa Puzic

I’m a QA Engineer (Manual & Automation) with 3 and half years of experience in manual testing for web and mobile applications, as well as web automation testing. I’m especially strong in writing automated UI and API tests and pairing that with careful manual validation.

In my most recent role, I worked on a sports betting and casino platform for Web, iOS, and Android, including a dedicated BackOffice application. I automated and maintained UI test scenarios with Playwright (JavaScript), used API-based test data setup to improve speed and stability, and helped achieve the highest automated test coverage on the BackOffice due to my responsibility for configuring Web and iOS content and functionality.

I’ve consistently delivered quality through smoke and regression testing within agile delivery. I’ve identified, reported, and tracked bugs across the development lifecycle, and participated in incremental application delivery using Kanban, presenting completed feature sets to the client after each increment.

Earlier, I performed Acceptance Testing in bi-weekly Agile sprints, automated 50% of UI regression cases with Playwright (TypeScript), and reduced manual regression time from 3 days to 1.5 days. I also created and maintained test cases in TestRail, implemented positive and negative API scenarios with Postman-style workflows, and used Gherkin for clear BDD coverage.
