About

I am a seasoned QA Technical Lead/Software Developer in Test/QA Architect with over 15 years of experience in the QA field, including 9+ years specifically focused on Test Automation. Throughout my career, I have worked across diverse domains such as Medical, Banking, CMS and Analytics, E-Commerce, and Publishing.

My expertise lies in building Automation Solutions from the ground up, leveraging C# as my primary programming language and TypeScript with Playwright. I have also gained project experience with Java. I possess a strong background in designing and implementing various types of tests, including Unit, Integration(API), and End-to-End tests. Furthermore, I am currently expanding my skills by learning the Python programming language.

In addition, I am proficient in working with both SQL and NoSQL databases, REST and SOAP microservices. I have hands-on experience with Docker containers, Ansible scripts, and PowerShell, although I am continuously working on improving my DevOps skills.

One of my passions is collaborating with development teams to establish robust QA processes. I have successfully trained manual testers in test automation and seamlessly integrated automation practices within their workflow. Created new Automation solutions from the scratch and encourage and help to restructure legacy solutions in order to improve test script design experience
Outside of my professional endeavors, I enjoy sharing my knowledge and insights with the QA community. I actively contribute to QA-related articles on Medium, which can be found at my profile: https://medium.com/@dneprokos . I have also had the privilege of participating as a speaker in various meetups, webinars and training sessions.
