Data Analyst + Developer

I make complex things
feel straightforward.

Hi, my name is Justin, I’m just a guy who likes turning dumb ideas and mildly inconvenient problems into apps. Lately, I’ve been building apps for iOS and macOS.

Always curious

A bit about me

The through line is curiosity.

I made my first mobile game at 14. Since then, I’ve moved between code, analytics, operations, and customer experience—following interesting problems wherever they lead.

I graduated cum laude in December 2024 with a degree in Business Analytics. That background taught me to look past the surface of a problem: understand the system, find the useful signal, and build something people can actually use.

Today I’m most interested in focused software, thoughtful product decisions, and the small details that make technology feel less like work.
