Seongju Lee

I'm a software engineer with 9+ years of experience building and scaling healthcare platforms, real estate tools, and data pipelines. Currently at Berry Street. Before that, I was at Thirty Madison (acquired), where I helped scale the platform from Series B to $250M ARR serving 2M+ patients.

My principles are simple — stay practical, stay curious, execute. Lately, I've been pretty excited about how AI is changing the way we build software. I don't think I've handwritten a function in a while.

For the full rundown, here's my resume. You can also find me on GitHub and LinkedIn, or send me an email.
