I’m Karl! I help build software products for a living, and try to make sense of the world by writing, and sharing it to see what resonates.

Most recently I founded a procurement software startup, built global payroll 0 to 1 at Rippling, and built out the checkout suite at Xendit. I also helped build Vaccinate California during the pandemic.

Here’s some of my writing that’s resonated with people:

Career advice for people with bad luck (Hacker News discussion)

Commenting vs. making (Hacker News discussion)

The job status cycle

Weird stuff

How to kill a project
