<about_me />
I’m a developer focused on building meaningful digital products: web apps, mobile apps and tools that connect with real users. I care about clean architecture, performance and long-term maintainability.
Over the last years I’ve worked on robotics projects, Android apps, and full-stack systems – from API design and databases to UI/UX details.
