My job experience

2022-2025

Developer and Technical Artist

Catness Game Studios . Castellón, Spain

Developer and Technical Artist

During my time at Catness Game Studios, a company specialized in video game porting, I worked on the technical art side of the porting process. My responsibilities focused mainly on performance optimization and the development of internal tools that automated or streamlined both the optimization workflow and its management. I also continuously monitored project performance and created tests and objective metrics to evaluate the real impact of each optimization, ensuring that improvements were measurable, reproducible, and aligned with the requirements of each target platform.

2020-2021

Junior Web Developer

Everycode . Valencia, Spain

Everycode SL

During my time at Everycode, a company specialized in web development and third-party digital accessibility, I was responsible for implementing their accessibility system across various websites, particularly governmental platforms. My work involved integrating and adapting the necessary tools to ensure that any user —regardless of their disability— could navigate and access the site properly. This included improving semantic structure, enabling full keyboard navigation, supporting screen readers, and meeting relevant accessibility compliance standards.

2019

Intern developer, Unity

Mind Trips . Valencia, Spain

Intern developer

This was my first work experience in the industry, where I worked with Unity and the Vuforia augmented reality SDK. During the internship, I was mainly responsible for designing and developing a virtual museum application for the Mora de Rubielos City Council together with two other team members. My tasks included integrating the artwork into the project, creating particle effects and shaders optimized for mobile devices —which were much more limited at the time—, as well as handling a large part of the programming logic due to the small size of the team. I also contributed to several smaller projects related to Augmented Reality and Escape Rooms, which I was unable to finish as my internship came to an end.

Skills

My skill set is very diverse:

Solid foundation in mathematics applied to graphics and simulation
Deep knowledge of programming on both CPU and GPU
Development and optimization of shaders and rendering techniques
Artistic skills both in visual design and execution
Experience with multiple game engines and internal engine modification
Creation of tools and pipelines to support artistic workflows
Advanced optimization for hardware and resource-constrained platforms

A selection of my work

3D Mesh Voxelization

This was my final degree project. By that point, I already had a strong interest in computation and graphics processing. At the time, I became particularly interested in volume representation in computer graphics, especially after I started reading the development diary of Dennis Gustafsson (Tuxedo Labs), where he showcased the development of the voxel engine used to create the video game Teardown, one of the most technically impressive games I have ever seen.

For this reason, I decided to work on something related to this topic, and I chose to …

Marching Voxels

Following my Bachelor’s Thesis on 3D mesh voxelization, I continued exploring volumetric rendering methods. One such method is the marching cubes method, which consists of dividing the rendering workload into blocks of 8 voxels (a cube) that can be rendered independently. This allows for massive parallelization in the drawing process, drastically decreasing the rendering time of the voxel structure while maintaining the simplicity of only having to analyze a few voxels in each iteration. This distribution makes the function a perfect …

Xuan Yuan Sword VII

One of the projects I participated in during my time at Catness Game Studios was the Nintendo Switch port of the video game Xuan Yuan Sword VII. The project was already underway when I joined, and my main tasks involved visually adapting the game for the console without compromising performance as much as possible.

Metamorphosis VR

This Quest 2 and Quest 3 port was one of the most technically complex projects I have ever undertaken. Not only was it my first time working in VR—which forced me to learn a vast array of new techniques and concepts—but I also had to meet the strict performance requirements of stereoscopic rendering, maintaining a very high framerate and resolution on hardware comparable to a 2020 smartphone. Additionally, we were a small team of two people, and our timeline was limited to just 9 months.

Raymarching clouds

Raymarching is a very powerful technique that can be used not only as a basis for rendering objects, but also to create various special effects, especially those involving volume rendering. I made this project to understand the basics of the raymarching technique. It is worth noting that in this project, no special attention was paid to performance or code adaptability; instead, it is a dissection of the raymarching process to better understand its inner workings.

The Bridge Curse: Road to Salvation

This was my first professional project directly related to the video game industry. My role involved supervising and correcting graphical issues arising during the porting process, as well as maintaining performance across all platforms (PS5, PS4, Xbox Series X|S, Xbox One, and Switch) at acceptable levels for each target. Additionally, I was responsible for implementing the game’s English dubbing and supporting other programming-related porting tasks.
