Vitalii Ivanov.
I build mobile and web products end to end — native iOS and Android, React Native, and full web platforms — with two decades of engineering behind them.
I run my own practice and work with product teams on a B2B basis. My primary ongoing engagement is a long-term partnership with many-to-many, a software studio.
