I've taken Jas Wallet, Nazarbayev University's campus access and identity app, from its first commit to public release on the App Store and Google Play. I owned a 34-module Flutter codebase, built its design system, and integrated SALTO mobile access so students can unlock campus doors with their phones.
I build production mobile experiences with Flutter, Dart, Kotlin, and Swift, including secure PIN and biometric flows, Bluetooth Low Energy integration, push notifications, monitoring, deep links, and multilingual support. I also wrote 1,300+ unit and widget tests for Jas Wallet and set up release tooling with Firebase, Sentry, and Mixpanel.
I've also built authentication and profile features at Innu.kz, an accessible appointment-booking flow at PhyDoc, and a live English learning platform for web, Android, and iOS. For my capstone, I led a university course-planning tool backed by FastAPI and PostgreSQL.
