Feel free to check out my GitHub account for an overview of my public programming work. For a detailed view of my professional experience, please refer to my LinkedIn profile.
Engine Programming
My experience in game engine programming ranges from hobby 2D engine work to developing commercial AAA engines, like IO Interactive’s Glacier. The details list as follow:
- Glacier Engine Animation Runtime. [info]
Work on animation runtime and tooling for IO Interactive’s proprietary engine, Glacier, powering games like HITMAN, 007 First Light and Project Fantasy. My main responsibilities during my tenure at IO Interactive include:- maintain and implement a variety nodes in for animation networks;
- work in core animation runtime features, like motion matching and cinematics;
- add diverse runtime debugging functionality and visualization using ImGui;
- implement and maintain IK features, such as head and torso look IK;
- fix buggs and issues in different animation systems, from cinematics and camera authoring, to IK or animation clip compression.
- Xaloc. [source code]
A 2D game engine written in C++. It’s an engine with an ECS approach, that supports OpenGL rendering and allows C# scripting through mono.
Tools Programming
I have professional experience developing tools for indie and AAA teams, in both C# and C++. The most remarkable work list as:
- Glacier Engine Animation Toolset. [info]
Work on animation runtime and tooling for IO Interactive’s proprietary engine, Glacier, powering games like HITMAN, 007 First Light and Project Fantasy. My main responsibilities during my tenure at IO Interactive include:- maintain existent animation tools, written in C# and WPF;
- work on tools to author and process animation assets of different kinds;
- design, implement and maintain a new curve editor for the Engine;
- diverse general editor and tooling work.
- TexWriter. [source code]
A shader-based image genrator, built using C++, OpenGL and ImGui.
- Rosetta.
Localization tool written in C++, using XML, OpenGL and ImGui. Used for the game localization process in Meteorbyte Studios releases. Provides basic functionality, such as basic project statistics, text search and filtering, content preview with different fonts and character sets, and string comparison among different languages.
- Buildbot Fork.
Used Python and Buildbot to develop an internal Continuous Integration tool, which automates PC and PS4 builds.
- Deck RX Toolset.
Tile-based level editor for in-game circuits. Programmed as a standalone C# Unity application and outputting level data in both JSON and binary file formats.
- Ignited Steel Toolset.
Multiple Unity extensions and custom tools for the development of the console versions of the game, including:- a “sprite stack” mesh generator, which allows the preview and generation of sliced mesh assets from a given set of sprites,
- a Localization Scanner, with the ability of checking the whole asset database looking for unlocalised UI elements or miss-configured font asset references.
- Songs of Steel: Hispania Toolset.
Designed and implemented multiple key tools in asset creation pipeline for Songs of Steel, a narrative strategy game. Among them:- node-based editor for Narrative Designers to structure both quests and dialogue assets in Unity,
- in-engine hexagonal tilemap editor, allowing the modification of navmeshes, level terrain conditions, trigger areas and enemy spawn zones.
- Unity extensions.
Vast work in custom Unity tools and extensions for the Unity Editor, to deliver the best-fitting toolset for artists and designers’ needs in each project.
Graphics & Tech Art in Unity
My expertise in Unity extends to the graphics-related aspects of the engine. I’ve participated in multiple projects with responsibilities on design and implementation of custom Render Pipelines, as well as doing technical art work of different kinds. Find some examples here:
- PJRP. [source code]
PBR render pipeline built from scratch in C# for Unity, fully working in PC, Nintendo Switch, Xbox Series X/S PlayStation 4 and PlayStation 5.

- Deck RX. [Steam]
Developed the game as Graphics Programmer and Tech Artist. Work in this project includes:- modification and extension of Unity’s URP forward renderer to add deferred features,
- toon-like illumination and fullscreen outline effect,
- environment fog and lighting for every world,
- in-game special effects and particles

- Ignited Steel. [Steam]
Designed and implemented a “Sprite Stack” based render pipeline, which achieves a pixelated 3D graphic effect using animated layers of 2D sprites.
General Graphics Programming
Other graphics-related toy projects can be found on my Github page:
- Vulkan Renderer. [source code]
Small project used to learn Vulkan.
- Path Tracer. [source code]
Simple renderer following Peter Shirley’s book “Ray Tracing in One Weekend”.

Bachelor Thesis
A Narrative Engine for video games with parallel and open storytelling.
Built as a core module in Project Attrah, its initial design and achitecture proposal was awarded Most Innovative Cultural Project of the year by the Ministry of Culture and Sports.
It has been used in the narrative strategy game Songs of Steel: Hispania, as the core system to handle the story events of the campaign.
Abstract
We have developed a multi-platform Narrative Engine which can help a video game build a story with different levels of developer and player authorship. We have accomplished this by abstracting all narrative occurrences that make the plot advance to different kind of Events, which can be triggered after internal changes of the game state. In addition, our system presents other sort of narrative utilities, such as Characters with different sets of skills and attributes, and multiple approaches to the way the previous-mentioned events are triggered, like Affairs that bind our internal system state to the game’s state or Event Pools, which will trigger events over time based on arbitrarily set priorities. Our system is currently being used by multiple in-development commercial projects.
