Back to original languageAbout Gabriel
Unity and Unreal Engine development for VR, XR, and digital twins + full-stack web and mobile development — from idea to working product. I help companies and institutions transform spaces, processes, and products into interactive 3D experiences, and build the accompanying web and mobile applications that function independently or in conjunction: digital twins, VR simulators, in-browser WebGL experiences, SaaS platforms, and mobile apps.
What I can build for you:
- Digital Twins: Interactive 3D replica of your plant, campus, or facility, with integration of CAD/Revit models and real-time data. I have developed digital twins of an entire university campus (multiplayer, real-time synchronization) and an urgent care center.
- VR Training Simulators: Risk-free and material-cost-free immersive technical training. I developed a welding VR simulator for university training, on OpenXR (compatible with Meta Quest and other headsets).
- In-Browser 3D Experiences (Unity WebGL): Virtual events, showrooms, and tours accessible via a link. My virtual job fair connected students with over 70 companies.
- Full-stack Web and Mobile Applications: SaaS platforms, administration dashboards, cross-platform mobile apps, and APIs. Stack: React/Next.js, React Native and Flutter, Node.js/NestJS, PostgreSQL and MongoDB, with cloud deployment and CI/CD. I co-founded a collaborative payment solution that won the innovation contest of Venezuela's national payment switch (Suiche7B).
Why work with me: Systems engineer with experience in Unreal Engine production in Spain and a track record of building real products — not demos. I deliver fast, validatable prototypes, communicate in Spanish and English (C1), and work European hours (full CET overlap). Tell me what you want to build, and I'll propose scope, deadlines, and budget within 48 hours.
