$ 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.
