About Me
I am Javier Riera, a Computer Engineer and Unity Programmer from Valencia, Spain. I develop gameplay mechanics, tools, and reusable codebases for games and interactive applications. I focus on maintainable architecture that helps teams iterate quickly, and I enjoy collaborating with talented people on interesting projects. Game jams are a particular passion of mine.
Game Developer and Unity Programmer
I have more than 5 years of experience with Unity3D. My work spans gameplay programming, design patterns, code architecture, rapid prototyping, tools for designers, and interactive XR and VR experiences.
- Email: javierriera97@gmail.com
- Degree: Master's Degree in Videogame Programming and Design
- City: Valencia, Spain
I specialize in applying reliable, well-known design patterns and adapting them to Unity in a way that game designers can use easily. This helps me iterate quickly on gameplay decisions and reduce implementation effort because the code is prepared for the inevitable changes of game development.

Master's Degree in Videogame Programming and Design
2020 - 2021
Universitat Oberta de Catalunya, Spain
Degree designed to be coursed for two years, in which Unity was used as the main tool to make videogames. I learned about level and game design, effective player feedback, videogame AI and behaviours, and improved my speed at quick prototyping.
Engineering Degree in Computer Science
2015 - 2020
Universitat Politècnica de València, Spain
College engineering degree in Computer Science, specifically in Software. This degree helped me understand complex concepts about programming, as well as cimenting the proper use of design patterns for bigger projects with multiple people working at the same time. Scalability, legibility and upgradability of code was a very important focus of this degree. On my thesis, I got a 9'5 out of 10. I coursed this degree in English for the first two years, being part of the High Academic Performance group.

Recommendations from people I have worked with across programming, game development, art, and data engineering.
Javi is, without a doubt, one of the most professional people I know. Not only does he meet
deadlines and expectations, but he also proposes creative solutions and is a great support and
reference for the artistic team of any project. The only bad thing is that, since he grew a beard, he
is so handsome that it is difficult to focus at work, so it takes us twice as long to do everything.
And I have my idea notebook full of portraits of Javi in different alternative realities. Today
I drew him as pirate.
Jaime Martínez Fernández
Storyboard, animatic, and 2D Animation Artist
Javi is a wonderful professional, both in a work environment and in his personal life. In every
opportunity I have had to work with him, he always manages to pleasantly surprise with his agility and
ease in leading projects, not only thanks to his quality as a programmer, but also because of his
great quality as a person. A work team with Javi is always a pleasant environment, where you feel
valued and motivated.
We could also add that he knows an absurd amount of The Simpsons references, which I
believe is a highly valuable job skill.
Sam González Morote
3D Animator / Game Artist
Working with Javi is always such a delight, like taking a bite from your favourite meal. He is
constantly eager to improve himself by experimenting with new tecniques and projects. Javi always does
what he loves with a big smile on his face and, with his energy and enthusiasm, he is able to inspire
everyone around him.
But most importantly, he has if not the best, one of the best laughters out there.
Ferrán Devesa Marco
Lighting and Technical Artist / Environmental Artist
I've known Javi for quite some time now, and we have worked together in many different scenarios, such
as studying our degree, working for the same company in the same team, and even sharing a flat for a
little while. Through each of these phases, which have been very different in themselves, a few
aspects from him have stuck with me: his innate passion for improving and exceling at his craft, his
kindness, and his soul-warming spirit. Throughout this time, we have helped each other both
professionally and personally, and I have learned a lot from him by having him teach me something new,
or just by merely paying attention to how he does certain things and adapting them for myself.
His programming and computer engineering knowledge are some of the most in-depth I have ever come
across, although he is constantly expanding and happy to share them. Javi also has a gift for
uplifting the room without losing focus on any goals, leading in a very natural way. He is definitely
someone I would always want to have on my team.
Alejandro Mor Michael
Data Engineer / Software Developer
I don't know a single person more passionate about his work than Javi. From a very young age he knew that he wanted to be a computer engineer, he has always been clear about it and has worked for it. So much so, that his favorite hobbies are programming his games, tinkering with new mechanics that could help him program faster, and watching videos that explain things related to his work. An anecdote that is especially funny to me is that, one time, he was quietly watching a movie online with his friends while programming, and no one even noticed! In short, Javi is a person who knows what he wants, works hard to get it and who does not settle for less than what he deserves.
