Arkadiusz Krakowiak is a software architect and domain-driven design enthusiast with a decade of hands-on experience building backend systems, primarily in the Symfony/PHP ecosystem. He has progressed from freelance web development to senior and lead engineering roles at GOG.com and contributor work on prominent open-source projects like Sylius, where he implemented core CRUD, CSRF protections, API refinements, and refactorings across product, order, and inventory domains. Comfortable both as an individual contributor and a technical leader, he has driven architecture and delivery while experimenting with Holacracy and collaborative organizational practices. Arkadiusz blends pragmatic engineering—BDD testing, interface refactors, integrity validations—with a strong modeling mindset rooted in DDD. Based in Łódź, Poland, he pairs system-level thinking with meticulous backend craftsmanship, often tackling the less-visible plumbing that keeps e-commerce platforms reliable. A curious learner, he actively surfaces domain constraints into code, helping teams translate business rules into robust, testable implementations.
