Things I've helped build.

Distributed object store backing internal analytics pipelines. Designed the replication protocol, led the migration from a third-party blob store, and cut storage costs by ~40%.

Internal job queue with strict ordering guarantees for financial transactions. Replaced a brittle cron-based system; zero missed jobs in 18 months of production.

A tiny log-search CLI that understands structured JSON logs without a schema. Pipe it anything; it figures out the shape and lets you query in plain English.

Embedded job queue for SQLite. No separate process, no network, no infra. Drop a Go package in and you have reliable background jobs in under five minutes.

A link garden — personal bookmarking tool that keeps URLs alive with snapshots and lets me tag and search them locally. Slow web philosophy.
