About

I like clean architectures, observable systems, and UIs that feel effortless. Tooling I reach for: React, Node, Docker, Terraform, AWS ECS, and Grafana/Loki.

Highlights
  • Built a secure homelab with DNS‑01 LE certs and per‑app subdomains
  • Containerized services with Compose; production targets on ECS
  • Designed spaced‑repetition learning flows for geography trainer
