Propham shows how I think about real business operations.

This short walkthrough follows a normal pharmacy workflow: an admin manages staff, private records stay protected, inventory is prepared, a staff member starts a sale, products are selected, payment is recorded, and the receipt is ready to print.

About David

I build with the business process in mind, not just the interface.

My strongest work is practical business software: tools with logins, roles, dashboards, data entry, inventory, sales, reports, receipts, and workflows people use every day. I care about whether the product makes the work clearer, faster, and easier to trust.
