Hi. I'm David Horstman.

I'm a fast learner used to living outside my comfort zone. I've taken on many different challenges throughout my career. Now it's time for a new challenge: working for you.

Learn about what I do

Here's what I can do.

Scientist. Teacher. Programmer. Jack of many trades, master of some.

Adept Programmer

I started off learning Java for a teaching job. Then I taught my self PHP, SQL, and C. After Lambda School, I have another full stack under my belt. Learn more.

Teacher and Mentor

Before I was writing code full time, I was teaching others how to write code. And make games. And build robots. All on the Arduino platform. Learn more.

Trained Scientist

I've studied Biology. I've studied Chemistry. I earned a Master's from Columbia studying Biophysical Chemistry. Learn more.

Here’s my most recent work.

From janky videogames in Processing to full-fledged web applications. It's been quite a journey.

Breakout

With three days of coding experience, I wanted to see how far I could push myself. Turns out, it was pretty far.
