About

I am a hard-working and dedicated architect and team leader with over 14 years of experience in the software industry. My passion lies in Domain-Driven Design (DDD), functional programming, types, and tests, constantly striving to step up, take ownership of products, and explore new paths to ease development and enhance software correctness. I am a quick learner, always eager to lead teams effectively, oversee priorities, and ensure deadlines are met. My expertise spans team building, software architecture, Azure and DevOps, productionizing machine learning systems, and server-side application development and web crawling. Throughout my career, I have held various roles that allowed me to apply my skills in different environments. As a Principal System Architect at The Motley Fool, I architected and implemented a content generation ecosystem based on LLMs. At ABB, I led the R&D team for the new Service Department, while at Magnify Logistics, I modeled next-generation relay systems and guided a team of developers. My tenure at Aterian Inc. involved optimizing cost and data processing pipelines and integrating machine learning models into daily operations. I have also worked as a self-employed contractor, migration consultant, and senior software developer, gaining experience with technologies such as C#, F#, Python, AWS, Azure, and many more. My educational background includes a degree in Software Engineering from the Academy of Information Technology in Poland. In my free time, I enjoy functional programming, physical therapy, movement, martial arts, and fiction.

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. “
