Backend-focused Software Engineer.

Good design, clean code and scalable systems. Strong in .NET, passionate about Go, DevOps and self-hosting. I also have experience with Angular and BI with QlikSense, giving me a full-stack perspective when needed. I experiment (and break things) in my homelab to learn how systems really work.

• Build backend services in Go and .NET
• Design systems that are simple, predictable and observable
• Writing small tools that solve real annoyances
• Explore distributed systems, infra, and tooling that makes dev life easier
• Automate everything I can, improving workflows and automating the boring parts
• Breaking things in my homelab just to understand them
• Keeping codebases clean, consistent, and enjoyable to work on
• Learning new tech deeply, not just “using it until it works”

• cutter: 🔪 A lightweight, fast URL shortener built with Go, HTMX and SQLite
• dotfiles 🗃️ Nix-based dotfiles and dev environment setup
• homelab-infra 🏡 IaC for my homelab: servers, VMs and self-hosted services automated with Terraform & Ansible
