I turn messy data into
something useful.

Data engineer and builder. I scrape it, pipe it, chart it, and ship it, usually because I was curious about something.

Bar chart of daily water use per billing period, with the landscaping and leak fix marked

Water Leak Detective

My water bill jumped to 9× normal after a new lawn went in. Five years of billing data showed it was a leak, not the lawn, dated its start to early March, and put the savings from fixing it at $860–$1,740 a year.

About me

Josh holding a camera

I'm Josh. I got into software because I had an idea for a business and couldn't stand letting someone else build it. The business was a highlight of my life, but the bigger takeaway was finding out how much I love writing code.

Since then I've worked at startups and larger companies in increasingly technical roles, mostly in data engineering and support engineering. My favorite problems involve pulling data out of awkward places, cleaning it up, and turning it into something a person can actually act on.

Away from the keyboard you'll find me playing basketball and tennis, cycling, hiking, or deep in a euro board game.
