(noun) a person who makes stuff, then makes a website to keep track of the stuff

I’m Eusa, a software developer in Calgary. I work on backend Java, Postgres, and the integrations that keep an oil and gas logistics platform talking to everyone else’s systems. Most days that means Java on Jetty and Guice, jOOQ and Flyway against Neon Postgres, and REST clients, webhooks and file workflows for partners whose formats I don’t get to choose.

Over three years and a few thousand commits on one codebase, the recurring themes have been shipping small correct changes into a large system, keeping production healthy from session-replay and error-monitoring alerts, migrating a live UI across two major framework versions, and lately wiring LLM and OCR extraction into a real document workflow. I have a soft spot for optimizing workflows: if a task gets done twice by hand, I’d rather spend the afternoon making it do itself.

I studied computer science at the University of Calgary. One of my final projects there was a data visualization about the semester I took seven courses at once, which is still on this site. Outside of work I photograph buildings, build things like a Discord bot that follows a friend’s Spotify, and start more side projects than I finish.

If any of that sounds like your kind of thing, say hi.

What you’ll find here

i·de·a

Half-formed thoughts I couldn’t leave alone. Some grow into projects, most stay as notes, and a few get written up here so I stop re-inventing them.

proj·ect

Where the ideas, the code and the photos collide. Usually a story about something that went sideways, told with charts, like the semester I took seven courses at once.

pho·tog·ra·phy

Mostly buildings, skies and whatever light I happened to catch on the way somewhere. No filters worth mentioning, just a lot of looking up.

code

Repos, experiments and the occasional tool I built because the existing one annoyed me. Java by day, whatever the idea needs by night.
