About

I am a seasoned programmer and software architect dedicated to following best software development practices, including the Software Craftsmanship approach, SOLID principles, and the agile manifesto. My commitment to these methodologies allows me to create high-quality software. In leadership roles, I emphasize teamwork and collaboration, ensuring that I work within the team rather than above it. My primary programming language is PHP, but I am always eager to learn new languages, currently focusing on Go. As a Senior Developer at RTB House Sp. z o.o. since January 2021, I have been involved in backend development using Symfony 3, REST API, and Docker, among other technologies. Previously, as Head of Software Development at E NET Production Sp. z o.o., I managed teams, consulted on architecture, and implemented Scrum/Agile practices. My experience at ArmorLab as a Full Stack Developer and previous roles in various companies have equipped me with extensive skills in backend and frontend development, DevOps, and project management. I hold a Bachelor's degree in Computer Science and Econometrics from the University of Economics in Katowice. Fluent in Polish and intermediate in English, I am committed to continuous learning and professional growth.

Best back-end engineers I've ever worked with...​

“I interviewed about a dozen different firms. DevsData LLC is truly exceptional – their backend developers are some of the best I’ve ever worked with. I’ve worked with a lot of very well-qualified developers, locally in San Francisco, and remotely, so that is not a compliment I offer lightly. I appreciate their depth of knowledge and their ability to get things done quickly. “
