About

I build practical systems with a polish: web apps, data pipelines, and automation that ship and scale. I like pairing strict structure with bursts of creative energy—think tidy architecture splashed with a bit of Jackson Pollock.

  • Full‑stack development (JS/TS, Python)
  • Data & BI (SQL, Power BI)
  • Automation (n8n, APIs, Webhooks)
  • Cloud (AWS, GCP)
