// VIDEOGAME PROGRAMMER
I'm a Game Programmer with a passion for the technical side of visual art. My focus is the intersection between code and visuals — building rendering systems, shaders, and procedural tools that make games look and feel great.
I've implemented PBR, Forward+, Deferred rendering, post-process pipelines and procedural generation systems in Vulkan. I understand what happens at the GPU level, which means I can debug, optimize, and build on top of engines like UE5 and Unity with real depth.
Based in Valencia, Spain — open to remote and on-site opportunities.
Custom rendering engine built from scratch in Vulkan and C++. Implements Forward+, Deferred and Deferred PBR pipelines with a Shadow Atlas for multi-light support. Full post-process stack — Bloom, Depth of Field and Motion Blur — all chained. Procedural generation systems: L-System tree/plant generator with 5 species, Simplex-noise forest placement, and Wave Function Collapse tilemap generator. ECS architecture with a Job System for async loading.
Top-down arcade action-comedy in UE5. Team project — responsible for gameplay systems, character mechanics and C++ architecture.
Unity bartender game — craft drinks and listen to customer stories. In development. Personal project.
Academic VR infinite runner in Unity. Focused on comfortable VR locomotion and interaction on Meta Quest 2/3.
AI demo in UE5 using Behavior Trees. Patrolling agents, 1v1 combat, and team-based combat scenarios.
UE5 puzzle game exploring gravitational manipulation and perspective shifting. Player must recover spaceship components to return home.
Computer Engineering thesis — VR Ping Pong on Oculus Quest 2. Focused on realistic physics simulation and haptic feedback.
UE4 prototype exploring interaction mechanics, atmospheric storytelling and tension-building for the horror genre.
Academic Unity runner built with a partner. First full game loop shipped — procedural obstacle generation and score system.
ESAT — Escuela Superior de Arte y Tecnología
Advanced rendering, C++, engine architecture, team game development. Built a full Vulkan engine from scratch.
Universitat de València (UV)
Software engineering, C++, linear algebra, physics simulation. Strong mathematical foundation for graphics and rendering.
LSyM – IRTIC
Simulator development for training and learning, VR integration, bug fixing and software solutions.
Quasar Dynamics
