About

I'm a problem-solver and that shows up in my interests too. I'll take a crazy route on a trip abroad if it means I get to see more — and I'll make it work. I will turn the smallest irritation in life into an automated solution if I can. I have always wanted to do things at the deepest level, whether that be planning myself instead of following a fixed tour, or rebuilding a workflow because the existing solution doesn't fit my needs.

My projects all start the same way: a real problem that needs solving, and the mindset to automate it rather than do it by hand.

This shows in the things I build. Whether it's saving myself five minutes checking for freebies, thirty minutes planning a trip or days of manual data processing, I like building tools that make life easier. I tend to work as close to the mechanics as possible — picking apart HTTP requests over using browser automation, or building my own processing tools so the solution does exactly what I need it to.
