At Freelance/Consulting, I architected and delivered Onesty from scratch in SwiftUI, scaling its Firebase and Core Data backend to support 10,000+ active users. For MVSocial, I reworked memory management and background threading, cutting cold starts to under three seconds and eliminating UI freezes.

I built DocCombain, an offline-first iPad document management platform with CloudKit synchronization for 50+ enterprise clients. I also delivered a scheduling app MVP with a custom task engine and In-App Purchases.

Earlier at Bacca, I designed enterprise document management architecture and led a team of six engineers across concurrent projects. I’ve also authored seven commercial iOS courses and mentored more than 300 developers.
