What I Do

⚡

PHP Backend Expert

13+ years building scalable backend systems. In love with Laravel and the entire ecosystem. Doctrine? Not so much.

  • → Laravel ecosystem
  • → Redis, MySQL/PostgreSQL, RabbitMQ/SQS/Pub/Sub
  • → API design & queue-based architectures
  • → SendGrid, Pusher, Docker
🎯

Tech Leadership

7+ years leading engineering teams. Building high-performing teams and shipping products that matter.

  • → Team building & mentoring developers
  • → Technical strategy & architecture decisions
  • → Agile methodologies & sprint planning
  • → Code reviews & engineering culture
🚀

Current Obsessions

Recently discovered the joy of self-hosting everything on my VPS. Who knew infrastructure could be this fun?

  • → Self-hosted stack: Traefik, Docker, Umami, Portainer, Netdata
  • → Building static sites with Astro + AI (brutally fast)
  • → Everything lives in GitHub - infrastructure as code

My Philosophy

"Code should be simple. Teams should be empowered. Products should solve real problems. Everything else is noise."

I believe in building things that work, leading with honesty, and cutting through the bullshit that slows teams down. No corporate jargon, no over-engineering, no politics. Just good code, clear communication, and shipping value.
