About me

I'm a Software Engineer specialized in mobile development with Flutter. I build enterprise applications from scratch, modernize existing systems and integrate REST APIs and databases to ship real solutions to production on Android and iOS.

My approach starts from the business logic: I analyze the problem, estimate the effort, propose solutions and work with stakeholders to define the best architecture. I move comfortably between the mobile frontend, the backend (.NET, REST) and databases like Oracle, PostgreSQL and SQLite, using Git, code review and Agile/Scrum.

I especially enjoy building my own products — like FinClarity, my personal-finance app — with care for quality, detail and a modern user experience. That mix of analytical mindset and product focus guides everything I design and build.
