What I'm looking for

I’m looking for a fully remote (or EU-friendly) role where I can ship polished cross-platform apps, own CI/CD and testing, and lead architecture and teams—while continuing to build at the library/open-source layer with Dart.

I’m a senior Flutter and mobile engineer with 4+ years shipping cross-platform products to the App Store and Google Play. I build with Dart, Riverpod, and Clean Architecture, owning CI/CD, automated testing, and release pipelines while staying deeply hands-on across app and library layers.

Beyond app work, I contribute to Numd, an open-source NumPy-style numerical computing library for Dart, where I’ve helped expand numeric support and implemented features like complex number modelling and HDF5 integration with tests, documentation, and usage examples. I also lead and mentor mobile teams remotely—setting architecture and coding standards, running code reviews, and acting as the technical stakeholder voice for international projects—while continuing to deliver real-world products as a founder and CEO.
