At SeverGroupMedicine, I own core patient-facing features across appointment booking, patient accounts, medical results, and online payments for around 100,000 users. I migrated a 1,200+ file production codebase from Swift 5 to Swift 6, reworking networking and ViewModel layers around modern concurrency.
I shipped the full bank card and SberPay payment flow, from SDK integration through payment states and failure paths. I also optimized the authorization request queue and built an in-app debug and feature-flag menu that helped QA engineers localize bugs faster.
At Garpix, I built an accessibility version across roughly 30 screens, with Dynamic Type, high contrast, visual themes, and English localization. I’ve also built reusable Swift packages, AR features, and mapping integrations, and at SimbirSoft I delivered a multi-screen fintech promotions and quiz section.
