About Me

Mobile developer focused on building apps that solve real problems

Hey! I'm Billy, a mobile developer who gets excited about turning ideas into apps that people actually use. I've been building mobile applications for over 8 years, working on everything from health tracking apps to video messaging platforms.

What I love most is the challenge of taking a complex problem and creating a simple, intuitive solution. Whether it's helping people manage their health goals or making video communication effortless, I believe good apps should feel natural to use.
