What I'm looking for

I'm looking for full-time collaboration on mobile products where I can build reliable Flutter and iOS applications, contribute to architecture and releases, and work across European or overlapping international hours.

I've built and maintained production Flutter applications for SiriusIQ's healthcare automation platform, combining scalable Dart architecture with native iOS integrations.

I deliver end-to-end mobile features across Flutter, Swift, Firebase, REST APIs, authentication, push notifications, deep linking, testing, and CI/CD. I also integrated the OpenAI API and AI-powered recognition workflows for Roof ScanAI field inspections.

Before Flutter, I spent years shipping native iOS products for Discovery Vitality and Banuba, including healthcare applications, AR face tracking, real-time video effects, and computer-vision experiences. I focus on stable releases, performance profiling, maintainable architecture, and practical debugging.

I've also taught iOS development and mentored students through hands-on projects, code reviews, and engineering best practices.
