Software Engineer

Hi, I'm Jeffrey.

I'm a software engineer who enjoys solving problems with code. These days I'm mostly living on the frontend, however I have experience across the whole stack. I'm always happy to put on any hat when the need arises. In the words of Ryder, “No job is too big, no pup is too small!” (Why do I know this?)

Currently, I lead frontend at ProtonLabs, where I've helped ship AI products such as a PDF Chat app ( AskYourPDF), Cursor for document writing ( CoWriter) and others to hundreds of thousands of users. Previously, I've worked at Embrace Technologies and Mako Studios. In my spare time, I like to work with my mechanic on restoring my dad's J150 (Toyota supremacy baby). I also like to play video games (currently playing God of War 2018 - RDR2 was robbed btw).
