About Me
I'm a Senior Unity Developer with 6+ years of experience building mobile games and interactive applications. I design gameplay systems, scalable architectures, and production-ready features — from combat and turn-based mechanics to UI, monetization, and live game operations.
I've contributed to mobile games with over 20M downloads at Roshka Studios, and I also develop production iOS applications with Swift and SwiftUI — including secure banking apps and solo-published trivia games on the App Store. I care about performance, clean architecture, and shipping software that holds up in real production environments.
