My Story

I’ve been a “developer” unofficially since around age 12. In the old days of RPG Maker and Game Maker, I’ve always strived make games for the rest of my life.

I never got into coding directly from there, but after learning a bit about the game making process in general, and creating some tutorials for specific game engine mechanics, I’ve felt the need to compile my content under one website which I would attempt to grow into a community (spoiler alert: it didn’t), so in that spirit, I’ve learned to create websites.

And it hooked me.

Ever since, I’ve been ironing my skills in HTML, CSS and JS, while keeping game development and other coding areas as side-hobbies.

Today, I am a freelance full stack and app developer, ready to make things for you.
