My name is David. I have a lot of interests, but mostly I just like to figure out how the world works.

What I’ve done for money

I started my professional life as a US Sailing–certified instructor at Longshore Sailing School.

Once I finished school, I went to work at a small federal contractor in the world of cybersecurity. They have leaked into the private sector a bit in the form of Carbon Black, Red Canary, Randori, and a few others.

After a brief stint as a quant, I now work with ThreatKey to help companies manage the overwhelming amount of shenanigans that go down in their SaaS products.

In case it’s not obvious, this is a personal blog. Eveything I write here is my own opinion.

What I’ve done out of the kindness of my heart

I made a tic-tac-toe AI using only the Python standard library.

I made a nonogram solver in Python and wrote a post about it. I also made a similar solver in Rust and wrote a post about that one too.

I scraped Reddit because r/random wasn’t random enough for my taste and I wanted numbers to back up that feeling. I wrote a post about that as well.

I made a toy dataset about an imaginary railroad company.
