I build real apps & fast websites.

Eight years and 30+ projects shipping production iOS apps and hand-coded websites — eight this year alone, four of them launched publicly. The next one could be yours.

Hi, I'm Sean.

I've spent eight years turning ideas into things people actually use — production iOS apps and websites that load fast and look sharp. No agencies, no hand-offs, no templates. You talk to the person who writes the code.

Over the years I've shipped 30+ projects — eight this year alone, four of them launched publicly: three iOS apps and a website, each one designed and built by hand. I care about the details most people skip — the animation that feels right, the page that loads instantly, the feature that just works.
