About

I have over a decade of experience as a PHP Developer, working on various projects and gaining expertise in multiple frameworks and technologies. Starting in 2009, I developed and maintained an accounting system at Tax Care in Warsaw, where I eventually became a Senior Developer. I have also led development teams, as I did at Coinfirm, an international startup focused on AML/KYC solutions. I have worked on numerous significant projects, including a booking platform for pet parents at HiPets, where I gained experience with Symfony-based applications and learned CQRS and Calendar Recurrence Rules. Additionally, I contributed to the development of a Business Analytics Reporting System at RTB House, a global marketing technology company, and created an investment system for Real Estate Investors in the U.S. My current role as a Senior Software Engineer at Realeye involves working on an online neuroscience platform for webcam eye-tracking and facial coding. Throughout my career, I've consistently utilized technologies like PHP, Symfony, MySQL, Docker, and various other tools, adhering to SOLID principles and SCRUM methodologies. I hold a Master’s degree in Computer Science from the Military University of Technology in Warsaw.

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. “
