Message

At Trustly, I engineered a Java, Selenide, and Cucumber automation framework that reduced manual sanity testing from 6–8 hours to minutes. I also built a maintainable testing ecosystem adopted across squads and developed AI tools for test generation, code review, and troubleshooting.

Before Trustly, I developed fintech experiences at Movile Pay, including a Backend-Driven UI and Android digital account, and worked on enterprise software at CI&T. At Venturus, I built Android applications and digital TV functionality for Motorola smartphones.
