I've been in the tech industry for over 11 years now, building solutions that involve software and hardware integration to meet a customer requirements in specific fields such as logistic and Healthcare. That experience has given me a deep understanding of how products work from the ground up and why reliability is so important for the end user. Although not all of that experience was strictly in a QA role, I was applying all the SDLC concepts as a Manual tester delivering high-standard solutions. Eventually, I started my transition into QA automation, which is where I've focused my last 5 years, most recently, at Source Meridian, I was responsible as well as manual testing and also for the automation strategy for Payment Portal product (Integrichain project). There, I led the transition from legacy Java system devoloping a testing suite Selenium Web Driver with Pytest to a modernized Angular application, where I implemented a new automation framework using Playwright with Python, I built both frameworks from scratch. As a result We managed to increase regression coverage by 70% in legacy App (UI side) and an additional 40% on the new platform for both API and UI.
Beyond just writing scripts in different programming languages, I have experience doing test automation using Postman app for backend and Jmeter app for performance analysis. I consider myself a self-driven person who's always looking for ways to make the testing process faster and more transparent for whole team.
