Hi, I'm Sebastian
Waloszek — a senior Flutter developer and mobile engineer focused on building scalable,
accessible, and beautifully crafted digital products.
With a strong background in mobile
architecture, cross-platform development, and UI/UX design, I've helped startups, agencies, and
enterprise clients bring high-quality apps to life across iOS, Android, and web platforms. My approach
blends clean code principles, performance optimization, and thoughtful user experience — whether I'm
leading a design system rollout, improving app accessibility, or engineering complex features from the
ground up.
Let's turn great ideas into seamless, intuitive apps that work for everyone.
