Born in Granada, Spain, I found my passion about software development and start self-learning programming. After completing a bachelor in Electrical Engineering, I jumped into software development positions in Granada and then I moved to Switzerland where I currently live.
During my career I’ve worked in projects related to: distributed systems with pub/sub protocol DDS; sport timing and live TV production; DevOps projects; backend frameworks; and collaboration workflows, quality assurance and release management.
Apart from software development, I was able to grow on operational skills by having the role of senior technical operator of timing and scoring systems in the Olympic Games at Tokyo 2020 and Winter Olympic Games Beijing 2022. I did setup of network infrastructure, hardware and software and operation of software during sport competitions. I was the last level of support engineer helping teams to troubleshoot network protocols and software issues in critical moments.
As a hobby I maintain several open-source projects and frameworks for game reverse engineering (ROM hacking) and fan-translations. I study and analyze low-level details of game consoles and debug and write assembly code (ARM). I help teams to translate video-games acting in a role usually known as Localization Engineer. I make programs to edit proprietary formats of text, image, font and audio files.
I also love to give technical talks at conferences and online.

Talk at the DevFest 2018 organized by the GDG Jaén (Google Developer Group). The presentation is about a Twitter thread I did on July. For a week I was figuring out how the game Pokémon Mistery Dungeon Explorers of Sky from Nintendo DS generate and validate a kind of password for rescue missions, special events and object sharing. It almost a study of the assembly code of the game with some notes about the implementation. Code repository
Live streaming from Twitch requested by the TraduSquare community. This time I talked about the file format of the images, sprites and textures in video-games and all the kind of compression and techniques used in the Nintendo DS. Slides
Live streaming from the virtual reality platform AltspaceVR. The talk explains different topics and concept related to text formats like encodings, tables, fonts and compression. Slides
Talk at the JASyP (Jornadas de Anonimato, Seguridad y Privacidad). Organized by the group Interferencias in the University of Granada. I talked about the security mechanisms like encryption that we can find inside of the video-games with the goal to obfuscate their files to avoid hacks, mods and fan-translations.
Talk at the IEEE Developer Days organized by the association IEEE Student Branch of Elche. I talked about the Industrial Internet of Things (IIoT) and the main network protocols and framework in the market. I gave details on how one of them, DDS, works with a demo.
