About

I am a seasoned technical leader with 20 years of experience in the IT industry, including 10 years in leadership roles. My journey has taken me from a developer to an architect, and eventually to senior management positions. I've worked across various regions, starting in Poland and expanding my expertise throughout Europe, ultimately thriving in a global product organization. My career has been marked by innovation, where I've applied my skills to hardware, software, and most importantly, people management. I am deeply committed to fostering alignment, strategy, and the development of successful products, and I'm a strong advocate of Kaizen, the Toyota Production System, and Agile methodologies. Currently, I serve as a Senior Engineering Manager at Equinix, where I've played a pivotal role in establishing a new Product Development Center. Since joining in 2018, I've successfully built a team of over 150 talented individuals, maintained a retention rate of above 90%, and mentored the next generation of managers. My experience also includes roles such as Head of Development at KMD, Director of Mobile Development at Wirtualna Polska, and several key positions at Grupa o2. Throughout my career, I've consistently driven technical transformations, from revamping software development life cycles to leading the adoption of DevOps methodologies, all while ensuring the successful delivery of complex, high-impact products.

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. “
