Zeeshan Qaswar

Senior / Lead Unity Engineer
Multiplayer · Performance · Production Systems

I build and stabilize complex Unity systems across games and real-time applications. With 7+ years of professional Unity development, my work spans multiplayer integration, production architecture, performance and memory optimization, mobile engineering, and hands-on technical leadership.

Engineering Focus

Multiplayer Systems
Photon Fusion, Photon PUN2, host/client architecture, authority models, replicated state, networked gameplay, and host migration.

Performance & Memory
Unity Profiler, memory diagnosis, Addressables, asset lifecycle, progressive loading, UI optimization, and mobile constraints across iOS and Android.

Production Architecture
C#, modular systems, MVP-style UI architecture, interfaces, services, dependency injection, and production integrations with PlayFab and Firebase.

Technical Ownership
Hands-on technical leadership, code review, mentoring, cross-team collaboration, debugging, and production delivery.
