Business software I've built: billing, POS, pharmacy, workforce and ERP

Real systems for real operations. Each project has a case study that covers the problem, the architecture, the decisions and what I did.

The work behind the interface

Business workflows become software when the details are made explicit.

A checkout has to agree with stock and tax. An approval must survive a change of shift. A staff login should lose access when a session is revoked. These are the problems that shape my work across retail, restaurants, accounting, workforce operations and developer infrastructure.

The case studies show the data models, security boundaries, deployment choices and tradeoffs behind each product. Where source code is public, I link to it so the implementation can be examined directly.
