Senior Engineer at Catches
CV
Currently, I’m serving as a Staff Software Engineer at Existent, where my mission revolves around simplifying the creation process for XR applications. Here, I delve deep into the intricacies of spatial computing, striving to empower developers to weave immersive experiences effortlessly.
As an SDK Technical Engineer at Bytedance's PICO XR Team, I helped game developers create riveting XR games for PICO headsets.
In my previous role at Tencent-owned game studio Sharkmob, I was an Associate Lead Gameplay Engineer working diligently on a top-secret AAA multiplayer game utilizing the impressive Unreal Engine 5. Before this, I worked with HTC Vive as a Developer Relations Engineer. This role provided the opportunity to act as a vital conduit between Vive Engineering and the EMEA clientele and VR developers, fostering the creation of high-quality VR content across an array of VIVE hardware.
An exciting highlight of my career was my collaboration with Framestore, an Academy Award-winning creative studio. There, I developed Virtual Production tools and interactive XR experiences for prestigious clients like VW China and Warner Bros. My experience also extends to game development, as exemplified by my time as a Games Programmer at Electric Square where we launched the highly popular racing game, Forza Street, in partnership with XBOX Studios.
With an MSc in Computer Graphics, Vision & Imaging from University College London, and a Master of Engineering from the University of Patras, I'm equipped with a solid theoretical foundation to complement my practical experience.
When I'm not immersed in the world of VR and game development, you can find me exploring the wonders of 3D printing, creating everything from board game pieces and F1 wheels to lightsabers. My passion for all things tech is truly all-encompassing, and I bring this zeal to every project I undertake.
