About
"80% thinking,
20% coding."

I'm Karan Mali, a backend-first engineer who believes the best software is built by thinking deeply before touching the keyboard.

Currently at Ajar, building production backend systems. Previously at Autonomis and PixelSaffron, shipping RBAC platforms, multi-tenant architectures, payment integrations, and AI features.

I write about backend engineering on Medium. Latest: "The ORM Trap That Cost Me a Backend Job."
