About

I am a motivated Senior Fullstack Developer with a decade of experience in programming. Throughout my career, I have developed a strong passion for learning new technologies and continuously improving my skills. I am proficient in team management and technical leadership, which has allowed me to excel in various roles and projects. My recent experience includes working as a Senior Fullstack Developer at Diffco in Sunnyvale, where I was involved in AI-enhanced live online teaching projects, and at Startup House in Warsaw, where I managed teams and contributed to AI and media-related projects.

My technical skills include JavaScript, TypeScript, React, NodeJS, GraphQL, and various databases and testing libraries. I am fluent in English and a native speaker of Polish. My soft skills include team management, mentorship, knowledge sharing, problem-solving, and a proactive approach.

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. “
