# Hi, I'm PRB

[RSS](https://prberg.com/rss.xml "RSS Feed")

I'm a software engineer and open-source developer with 12+ years of experience, now on sabbatical. I co-founded [Sablier](https://sablier.com/), a VC-backed crypto payments startup, and ran it from 2022 to 2026. I also created [PRBMath](https://github.com/PaulRBerg/prb-math), the most popular fixed-point math library in Solidity.
