I build backend infrastructure for things that need to stay running.
I'm Inderjit Singh — a backend & infrastructure engineer, and co-founder of credChains. I work in Go, ship behind HTMX, and run my own goquorum homelab on Proxmox & OPNsense.
I pick problems that look like fun and work in the open where I can.
credChains — credentials, made portable.
A platform for verifiable credentials and trust networks. We're building the infrastructure that lets credentials move with people, not paperwork. Secured by goquorum blockchain, Services in Go, HTMX-powered admin, NATS for messaging, OpenBao for secrets.

credChains & tech I work with
What I'm building, and the open-source tools that show up in my stack — NATS, OpenBao, Proxmox, OPNsense, GoQuorum.
What I reach for
The languages, runtimes, and tools that survived the curve. Small, sharp, boring things that compose.

The product. Verifiable credentials infrastructure. Have a look at what we're building.
Projects & what I build with
credChains is the main thing. Below it: open-source tools I run, lean on, or like to explore in my own homelab and side work.
// shipping
Verifiable credentials and trust networks — letting credentials move with people, not paperwork. Go backend, HTMX admin, NATS for messaging, OpenBao for secrets.
credChains for the US market. Same platform, regional tuning for compliance and integrations.
// open-source I work with & explore
Lightweight, high-performance messaging. JetStream is my default for anything that needs durable, ordered delivery.
Open-source fork of HashiCorp Vault. The secrets backbone in everything I deploy — auth, PKI, transit.
Daily-driver hypervisor for everything I run at home. KVM + LXC + ZFS, managed with Ansible.
FreeBSD-based firewall & routing. Edge of my network — VLANs, WireGuard, captive portals, the works.
Permissioned Ethereum fork. Interesting territory for trust networks and credential anchoring.
My default for anything UI-shaped. Server-rendered HTML, partials over the wire, no SPA tax.
Working stack
Tools that survived the curve. I prefer small, sharp, boring things that compose.
