Vlad Fedoniuk — independent software · Poland
Native Windows apps.
Polished UI, offline-first, code-signed.
Mostly .NET, mostly Framework 4.8 — the stack that gets out of the way. I care about architecture that stays maintainable and apps that don't need my servers to keep working. I use AI to move faster and still understand every line I ship.
