Full-Stack Developer

Howdy, I'm
Tom Cat

I build apps from the ground up – blending data, design, and blockchain. Currently crafting Expensei, a bilingual smart budgeting app for iOS (alpha on TestFlight, Android coming soon), while diving into Solana's Rust + Anchor world.

About Me

I'm an indie dev focused on building tools that I actually want to use – practical apps that make life easier and creative projects that spark imagination. From financial tech with Expensei to creative AI apps like Magic Story Buddy, I love crafting experiences that feel both functional and fun.

I'm soon to be active in hackathons, constantly learning new stacks like Solana, and always experimenting with ways to bring ideas to life across mobile, web, and blockchain.
