Software Architect & Indie Builder

Lead Developer Local-First Architecture MIT Open Source

Hi, I'm Kamal Jit. I designed and engineered Open Inventory to solve the fundamental pain points small and medium retail businesses face — a modern, reliable, and subscription-free POS and inventory system that works completely offline, keeps your data on your own device, and is built for real business needs.

I built this terminal with a strict local-first philosophy. All databases, sales history, and customer ledgers are stored securely on your own hardware with zero cloud dependency. My mission is to give retail businesses an enterprise-grade POS terminal that is easy to use, fast, 100% private, and completely free forever.

Ultra-Fast & Reliable

Optimized POS with instant billing and barcode scanning.

100% Local & Private

Your business data stays on your device. No cloud, no tracking.

Open & Customizable

Built for the community with MIT license and full source code.
