About

I build real-time 3D software that has to behave like the real thing. That covers a GPU fluid solver running 8 million cells live, CAD pipelines for digital twins, accurate cameras for virtual film production, and games with 600+ live agents at 60 FPS.

My current focus is robotics simulation: NVIDIA Isaac Sim / Isaac Lab, ROS 2, and a mixed-reality teleoperation pipeline that runs from a Quest 3 headset to a trained policy. I still write production C# and Python every day, and I lead teams when a project needs it.

Experience

  1. Lead Simulation Engineer

    Aug 2023 – Present

    Visionaries FZ-LLC · Dubai

    Technical lead on Business Heroes (team of 5). 600+ NPCs from 25 to 60 FPS, save migrations across patches, Azure telemetry. Steam 85% positive; taught at three UAE universities.

  2. Senior AR Engineer / Division Lead

    Nov 2022 – Aug 2023

    Pretia Technologies · Tokyo

    Led the entertainment and media division (5 engineers). Shipped 5+ AR products in one year and vetted 15+ technical proposals.

  3. Simulation Engineer (Technical Lead)

    May 2020 – Nov 2022

    Backlot Studio · California

    Led 8 engineers on a virtual-production tool. Simulated 15+ cameras and 30+ light fixtures accurately, streamed 2TB+ of sets through a sub-1GB install, and cut integration time by 16 h per scene.

  4. VR & Simulation Developer

    Apr 2018 – May 2020

    Elibre DMCC · Cairo

    Built a VR interior-visualization simulator. Procedural furnishing stages an apartment in under 2 min, so client turnaround dropped from 2–3 days to under 2 h.

  5. Unity Developer (Multiplayer)

    Jun 2015 – Mar 2018

    Bidaj Studio · California

    Owned the client architecture for a real-time multiplayer card game (up to 1,000 concurrent players). Photon PUN + Firebase, with 60% less desync.
