📝 Notes & snippets

75 public gists — a decade of things I had to figure out the hard way, kept so nobody has to twice:

• JWT auth + refresh tokens in Rails
• OpenResty (nginx + lua): redis connection pooling
• Measuring Ruby GC · Unaccent in PostgreSQL
• Let's Encrypt for Nginx (IPv6 + HTTP/2)
• SSH into Proxmox containers

_{Everything else — experience, stack, projects, contact — lives on the CV.}
