Projects

A selection of things I've built. Each one has a short write-up covering the problem, the approach, and what I'd do differently.

Lead engineer

  • Go
  • OpenTelemetry
  • ClickHouse
  • Grafana

Engineer

  • PostgreSQL
  • Python
  • Terraform

Engineer

A small CLI that took deployment from a fifteen-step runbook to one command, and made rollbacks something people were willing to do.

  • TypeScript
  • Docker
  • GitHub Actions
