THEUNIS DUMINY

building—thinking—writing

Hey, welcome. I'm Theunis.

My North Star is seeking the truth, which embodies an insatiable curiosity. I question relentlessly until I've gained a deep understanding or find another connection elsewhere.

You'll find me working on hard, technical problems with smart, driven people. I believe the whole is greater than the sum of its parts. Especially true for people.

For me, good is the enemy of great. This doesn't mean perfectionism at all costs, but if you're in the business of building, strive to build something great.
