I've built and modernized iOS and Android applications across SaaS, fintech, cryptocurrency, AR, and sports on-demand products. At ProSpace, I migrated iOS reactive code from RxSwift to Combine, introduced SwiftUI alongside UIKit modules, and maintained 90%+ crash-free stability.

I've delivered fintech applications from scratch at OJIRE Technology, built AR exploration features at Questeon, and enhanced real-time cryptocurrency trading applications at INDODAX using WebSocket communication.

As Lead iOS Engineer at STRONGBEE, I led a three-person team through code reviews, mentoring, technical planning, and architecture decisions. I work with Swift, Kotlin, modern mobile architecture, reactive programming, testing, CI/CD, and app-store releases.
