About me

I build software the same way engineers design systems: starting from fundamentals, understanding constraints, and scaling solutions into reliable architectures.

My focus is writing clear, maintainable systems that remain understandable as they grow.

  • 🔭  Currently building Sheep (inventory micro-SaaS) and contx (dev tooling)
  • 💡  I believe clean architecture is a competitive advantage
  • 🧩  I enjoy tackling domain complexity head-on
  • 🌱  Always exploring patterns that make systems more predictable
