Pietro Giuseppe D'Amico

Developer • System Architect • FreeBSD Enthusiast

I develop native solutions for FreeBSD, Apple ecosystem applications and manage FreeBSD servers. I have worked with Debian, Ubuntu and CentOS, created radio servers and managed complete infrastructures. In love with Unix/BSD systems (FreeBSD, OpenBSD, macOS) for their solidity, stability and reliability.

About Me

Passionate developer of servers and Apple ecosystem

My Philosophy

I prefer native and performant solutions, avoiding containers when not needed. I build projects from scratch with attention to architecture and security. Experienced with firewalls (Cloudflare WAF, Hetzner Firewall, PF on FreeBSD).

Tech Stack

  • Backend: Java, C#, PHP (enthusiast), MySQL, Redis, Kafka
  • Frontend: Swift (iOS/macOS)
  • Server: FreeBSD 15+, OpenBSD, Debian, Ubuntu, CentOS
  • Cloud: Hetzner + Cloudflare
  • Security: PF, Cloudflare WAF, Hetzner FW
  • Tools: Homebrew, NMAP
  • AI: Claude (code review & architecture)

What I Build

  • Server management panels in Java
  • Native Apple ecosystem apps
  • Pixel-art multiplayer games
  • Development tools for macOS
  • Enterprise mail infrastructures

AI-Assisted Development

I use Claude AI as an advanced assistant for code review, architectural optimization and refactoring. AI doesn't replace expertise, but accelerates the development process and validation of complex technical solutions.

PHP Enthusiast

Passionate PHP enthusiast. I've been using it for years for web projects, REST APIs and backend services. I appreciate its versatility, mature ecosystem and how easily it allows creating effective solutions. An often underestimated but extremely powerful language.

Unix/BSD Lover

In love with Unix and BSD systems. Experience with FreeBSD (primary), OpenBSD, Debian, Ubuntu and CentOS. I've also managed complete radio servers in the past. I consider BSD and Unix systems (including macOS) incredibly solid, stable and reliable - systems you can truly rely on in production.
