Hello, I’m Ateeque Ur Rehman. I am a dedicated Unreal Engine 5 specialized Technical Lead and Senior Developer focusing on what matters most in real-world production: stability, performance, and seamless interaction. With 3+ years of experience and 5+ shipped titles (spanning standalone Meta Quest and PC VR enterprise platforms), I specialize in: ⚡ Engine Migrations: I have deep expertise in leading complex UE4.27→UE5 migrations, refactoring deprecated systems, and adopting mobile alternatives to Lumen/Nanite while maintaining stable 72/90fps targets on Quest hardware. 🏗️ Enterprise Simulations: I build optimized, data-driven simulation architectures, branched task logic, and dynamic site simulations for massive-scale training (including VR platforms supporting 20+ concurrent government trainees per session). 🖐️ Advanced XR Interactions: I craft optimized, production-proven systems for hand tracking, eye tracking, passthrough AR, and complex physics-based VR interactions (Controller and Fallback layer inclusive). 📡 Cross-Platform Multiplayer: I specialize in authoritative client-server architecture, state replication, and session management for multiplayer simulations onstandalone VR (Windows/Android). My assets and tools on Fab are derived directly from the codebases I use as a Tech Lead for enterprise training and medical simulations. I don't sell gimmicks; I sell performant, production-proven code meant to save you weeks of debugging time on performance spikes and memory management. I also publish technical post-mortems and guides on Unreal Engine build pipelines on Medium. 🌐 Portfolio/Articles: medium.com/@ateeque.solangi 📧 Contact/Support/Custom Work: ateeque.solangi@gmail.com Hyderabad, Pakistan based (Remote)
