A note about skills:

There’s a list of skills here so people searching for buzzwords can find what they’re looking for, but what I’m really good at is problem solving and reading the documentation of new technologies when I need to learn them.

Geographic Information Systems (GIS)
Relational Databases
Twitter API
Google Maps API
Amazon Product Advertising API


After working as a professional web developer in the late 1990s and early 2000s, I decided to finish the college degree that I had put on hold earlier. I may have overdone things a bit, as I earned a BS in Mathematics, then another BS in Physics, and I am about to defend my dissertation for a PhD in Materials Science and Engineering.

As it turns out, the thing that I really enjoy doing is web development, from lovingly hand-coded HTML all the way to relational databases. I’ve been scraping the rust off those early 2000s skills and bringing them up to date. If you need a team member who makes responsive, high-performance websites, who learns and uses the best tools for each job, have a look at my résumé, and let’s chat.

I am most easily reached by email at tmangan@gmail.com.
