Myself

Software Engineer & Game Maker

Ever since I learned how to program in college, I loved making games and playing them with my family and friends. Listening to their compliments and feedback is what motivates me to make better and more fun games.
One of the reasons why I love programming in general is the aesthetics of code. Scalability, decoupling, optimal structuring, and focusing on human readability. These are what I pay really close attention to when I code to make it clean and concise.
