Some things I built

aptlens.fyi ↗ live site

apartment listings make you guess whether a building is exempt from WA's 2025 rent stabilization law and how good the noise insulation is between units. I built a site that pulls county assessor data for residential buildings in King County and answers both on a map.

Map of Capitol Hill apartment buildings colored by rent control coverage Building card showing a rent control exemption, a noise score breakdown, and raw county records

task-queue ↗ github repo

a task queue for agent work built on Postgres.

1 · the problem
one process · identical capacity for all
fetch io summarize llm price api draft llm send smtp

need 3× the llm work? clone the whole thing

no pool per task type, no dial per task type.

2 · how it works
ONE KUBERNETES DEPLOY agent orchestrator enqueue · never twice Postgres queue retry routed by type llm ×3 io ×1 smtp ×1 notify done
