$ whoami — software engineer / infrastructure nerd / builder
I build backend systems, home infrastructure, and things that make life run smoother. 10+ years writing PHP for fintech platforms by day. Nights and weekends I'm wiring up a Proxmox homelab and automating everything that'll hold still long enough.
