Episode 128

I spoke with Sergiy Nesterenko about:

* Developing an automated system for designing PCBs

* Difficulties in human and automated PCB design

* Building a startup at the intersection of different areas of expertise

By the way — I hit 40 ratings on Apple Podcasts (and am at 66 on Spotify). It’d mean a lot (really, a lot) if you’d consider leaving a rating or a review. I read everything, and it’s very heartening and helpful to hear what you think.

Enjoy, and let me know what you think!

Sergiy is founder and CEO of Quilter. Sergiy spent 5 years at SpaceX developing radiation-hardened avionics for SpaceX's Falcon 9 and Falcon Heavy's second stage rockets, before discovering a big problem: designing printed circuit boards for all the electronics in these rockets was tedious, manual and error prone. So in 2019, he founded Quilter to build the next generation of AI-powered tooling for electrical engineers.
