a builder, mostly.

cal is a pseudonym for someone who likes systems that don't fall over. distributed execution engines, fault-tolerant pipelines, the kind of infrastructure that stays quiet because it's doing its job.

most of what shows up here started as a problem worth solving once and turning into a tool: a download CLI that handles every source, a graph that maps how MCP tools depend on each other, a job-hunt pipeline that hits public APIs instead of scraping.

the throughline is taste — minimal surface, honest defaults, no magic. ship it, document it, move on.
