...project I've worked on is a photorealistic engine that simulates a variety of environments, and that is being used to train and validate autonomous vehicles.


  • Founder

    2012 - PRESENT
    • Produced mobile games to the app store from scratch, including back-end and multiplayer games, using Unity and C#.
    • Developed a UVLC, a Unity native store plugin to play videos based on libVLC, using C++ and C#.
    • Created a SteamVR UI plugin to use steam VR controls seamlessly with unity's UI system.
    • Developed an easy threading Unity plugin to make it easier for other Unity developers to use background threads and concurrency and to be able to seamlessly bring the execution back to Unity's main thread.
    • Created a game demo of augmented reality for a checkers game where the pieces are animated and look alive, rendered on top of the real world.
    • Published a Facebook multiplayer game based on the Pictionary game–one player tries to communicate something by drawing it in real-time while other players try to guess it.
    • Developed a casual VR game with Unity C# that challenges the player to find a hidden cow just by listening to its mooing. This technology has the ability to precisely locate the source of the moo sound.
    • Published a multiplayer version of the classic game "Asteroids" using Unity C# and Photon.
    • Created a proof of concept for a street fighter mobile game that considers the player's finger gestures instead of virtual joysticks and buttons.

  • Fierro a Fondo (Development)

    Unity-based in-race telemetry app to analyze driving performance with real-time telemetry and publish live timing. Providing accurate positioning, I developed a complex system to be able to compare the current lap and the previous ones in real-time.

  • Syncity (Development)

    A tool to generate photorealistic environments that will feed to neural networks to train and validate them. Developed using Unity (using C# and many shaders to achieve photorealism and simulate a variety of sensors), bridged using ICE to python processes that make the actual train or validation. Another challenge is managing a huge amount of models, which is solved by using asset bundles and keeping them synchronized with a SQLite database.

  • TNA VR (Adult Site) (Development)

    Developed a VR video player for the adult video website tnaflix, it allows watching 2D videos from their current catalog in a nice environment simulating a strip club. It also supports 180 and 360-degree experiences. It uses Unity and a custom libVLC plugin to play the videos.

  • Vantage TV - Coachella Experience (Development)

    Developed a live video streaming solution to allow the Coachella festival to be streamed to VIP assistants on the backstage. It uses Unity, libVLC, and FFmpeg

  • UVLC (Development)

    Unity native plugin developed in C#, C++, Java, and Objective-C. Integrates all VLC features inside unity allowing the playback of almost any video format inside Unity. It's being used in many applications, especially VR and AR systems.

  • Easy Threading (Development)

    Unity store plugin adding Tasks support (a .NET feature that wasn't supported by Unity until recent). It facilitates other developers with the use of background threads and gives the ability to easily redirecting the execution flow back to Unity's main thread. Publishing a unity plugin also requires giving support to the developers using it and listening to their feedback and bug reports. The plugin has great feedback on the unity store and has reached the top 10 in the scripting category for many months.

  • Checkers AR (Development)

    Proof of concept featuring the classic board game in augmented reality. Developed using Unity and Vuforia, rigged models animated using Mecanim.

  • Find the Invisible Cow (Development)

    Casual VR game, the player must find a hidden cow just by listening to its mooing. Which required the ability to precisely locate sounds in the 3D virtual space.

  • SteamVR-Unity UI Integration (Development)

    Unity store plugin that integrates Steam VR inside Unity's UI system.

  • Make a bag (Development)

    Developed mobile and web applications that allow clients to design and order their personalized purse. The apps provide tools to customize materials, colors, texts and even upload pictures to print them on the final purse.

  • Just Draw It! (Development)

    Facebook social game developed in Unity, based on Pictionary, the drawing is published and showed in real-time to the players using Photon. The players can guess the word in their language and the backend (developed in ASP.NET and MySql) handles the localization between languages. Guesses are also shared in real-time to give the impression to the players of being playing in the same room. Also had to implement an anti-cheating system (in case the player actually writes the answer), if more than 50% of the guessing players report cheating, the round is void.

  • Space Courier (Development)

    Unity game proof of concept based on the board game RoboRally. It's a mobile game heavily based on user interface interaction. I was developed using NGUI, a unity plugin which is the precursor of the current official Unity UI.

  • Asteroids (Development)

    Asteroids clone with multiplayer features. Developed in Unity, multiplayer synchronization is achieved using Photon, high scored are saved in a PHP backed with a mongo database.

  • Space Race (Development)

    Lunar lander clone game. Developed natively for iOS using objective C, physics using box2. It also integrates advertising services and in-app purchases.

  • iFighter (Development)

    Experiment to see how a mobile street fighter game would feel using finger gestures instead of virtual joysticks to control the characters.
