I love creating!

Software Engineer/Web Developer/Game Developer

I have 7 years of professional experience on Web Development. Most of my work on the web has been on the front end, programming user interfaces using JS, CSS, VUE, REACT and GSAP for doing (or what I think it is) pretty stuff.

As a Game Programmer, I've worked as a freelance and some personnal projects for around 3 years, mainly using UNITY and PHASER . I've done work ranging from Game Design, to Character Controllers , to AI programming .

As a programmer I excel at and love to work on developing stuff that can be animated; for the users to interact with; that requires certain level of aesthethics and some notions of design.

WEB DEV

I hate boring websites.

Dynamic, amusing and different content; it's 2025, and I think we can do so much better than static websites.

I love making different and fun content, that also fulfill its porpuse of sharing information, but capable of enriching the user experience.

Skills

  • CSS - Since 2017
  • JavaScript - Since 2017
  • HTML - Since 2017
  • Git - Since 2018

I'm still learning new things everyday, but I consider that I got a good expertice on front end development fundamentals

  • Gsap - Since 2020
  • Vue - Since 2019

I have experience with different JS frameworks like Vue and React, content creators like Elementor (1 year) and other frameworks and libraries like BS, JQuery and Gsap.

Game Development

Game Development and Game Design is what I love the most. As you see, I love making interactive and visually stimulating things, and games are all about that.

I love thinking on Gameplay Mechanism's, Game Architecture and learning about Unity, C# and game related stuff.

As I told you, all my work have been from freelance and personal projects, but I'm proactive with my Game Dev Learning and I always aim for the best practices and making fun and visually good games.

Here, take a look
