Hi, I'm Denis, a QA Engineer with 12 years of experience in the field.
My focus is Playwright (TypeScript), end-to-end and API testing.
About me
I'm a QA Engineer who loves my profession. I've tested everything - desktop applications, mobile apps, web applications, and even gaming machines. Recently, I've been focusing on web application testing, which has become my main area of expertise.
As a hobby, I enjoy frontend development, which gives me creative space and helps me better understand the architecture of the applications I test. This combination of testing and development skills allows me to approach quality assurance from a unique perspective.
