Marcin Łojewski
QA Engineer && Fullstack Developer
I’m an ISTQB Certified Tester with over 3 years of experience in testing web and mobile applications. I combine hands-on QA experience with backend and fullstack project work, which helps me understand software from both the user and engineering perspective.
By building applications and working with APIs, databases, authentication, and business workflows, I have developed a solid technical understanding of how modern systems are designed and implemented.
I see this combination of QA experience and technical project work as my biggest strength. I’m particularly interested in QA, Technical QA, and backend or fullstack development roles where strong product and quality awareness are an advantage.
