About

Frontend & Infrastructure Engineer based everywhere with a laptop.

I build web applications from pixel to infrastructure — Next.js UIs to GCP deployments. I care about developer experience, clean APIs, and tools that just work. When I'm not coding I'm shipping open-source utilities that solve problems I ran into myself.

DBMigrator

Database migrations, done right.

A .NET 10 CLI tool that migrates PostgreSQL databases between servers and sanitizes sensitive data with declarative YAML rules — locally, in Docker, or on Cloud Run.

  • Migrate between any two PostgreSQL instances — local, Docker, or Cloud Run
  • Declarative YAML sanitization — 5 strategies: static value, null, template, faker, SHA-256
  • Pre-migration validation — checks tables, columns, and constraints before touching the database
  • Real-time progress tracking during dump and restore operations

dns-sync

One binary. All your DNS.

A lightweight alternative to OctoDNS built on .NET. A single compiled binary that synchronizes your DNS records across providers and zones — no Python runtime, no complex setup, no lock-in.

  • Plan before applying — preview every create, update, and delete across all zones before a single record is touched
  • GitOps workflow — open a PR, get a diff comment, merge to apply; one uses: line in GitHub Actions
  • Multi-zone, single source — define records once in a zone file, deploy to every domain automatically
  • Multi-provider targets — sync to Cloudflare, Route 53, GCP Cloud DNS, Porkbun, and GoDaddy simultaneously
