Project History
I-Ching Application in Google Play
https://www.codeserk.es/project/i-ching/A React Native application I created for consulting the I-Ching oracle.
The main goal of this application was to learn a new way to develop mobile applications, but the result has exceeded my expectations. It's currently the first result for I-Ching applications, with more than 10,000 downloads and a score of 4.8 with more than 1500 reviews.

Codeserk Portfolio
https://www.codeserk.es/My personal portfolio, used to highlight and promote my work.
The implementation of this website marks an evolution in Avellana Colorá's performance. This public website uses a library that I built in TypeScript and reads all the content from the local filesystem (mostly from markdown files) and provides all scaffolding to build a public website. This application is built using Nuxt.js, and the content is generated and uploaded to Firebase.

Avellana Colorá Public Website
A public website to promote the products of an artist.
This application uses a WordPress instance to create content and a Nuxt.js application to show it. The public website is generated with every change in the content and served using Firebase. The media I used on the website is optimized to ensure we can maintain good performance.

Arena Heroes Game on Google Play
A game made using Unity, with some assets made by myself and some of them purchased. It was a collaboration with a friend from college.
The main mechanic of this game involves reaction time; you need to act fast to defend yourself from your foes correctly. Your fighter learns from your play style and reproduces it in online fights against other players. The game reached the Google Play store, and we increased the volume of players soon after. We even started to generate revenue. The back-end side of this project was initially parse.com, but that project was deprecated in favor of Firebase. That was why we removed the game from the store since we didn't have time to migrate.
