What I'm looking for

I’m looking to drive technical excellence on high-performance interactive games—owning full-cycle delivery, shipping multiplayer and AR/VR experiences, and integrating scalable backends, LiveOps, and monetization with strong engineering collaboration.

I’m a Senior Unity Developer with 8 years of hands-on experience engineering production-ready mobile games, multiplayer gameplay systems, and AR/VR applications. I’m known for owning full-cycle development—from prototyping through App Store and Google Play publishing—while building robust C# architectures.

I build backend-connected iOS and Android titles using C#, Unity, Firebase, PlayFab, and AWS, and I focus on performance optimization from day one. I’ve delivered 140+ remote projects with a demonstrated 100% Job Success score, and I stay collaborative and reliable with global clients, especially USA-based engineering teams.

In my recent work, I’ve led deployment pipelines and shipped monetization and LiveOps features like IAP, ads, cloud save, leaderboards, analytics tracking, and push notifications—always with strict store compliance. I also enjoy technical leadership, including mentoring and leading a lean Unity-and-Backend team to integrate complex systems, databases, and third-party APIs.
