Overview
A complete medicine inventory management and POS system built for a clinic with corporate clients including AQUA (Danone). Used daily in production by real staff with zero downtime.
The Challenge
The clinic needed a reliable system to manage medicine stock, handle transactions accurately, and serve corporate clients with different billing requirements — all running on minimal hardware.
The Solution
Built a full-stack application with Go backend, PostgreSQL, and React frontend. Designed the database schema from scratch. Deployed on a VPS with Nginx, fully self-managed including domain. After a security incident on first deploy — an exposed database port — hardened the entire infrastructure: database moved off public network entirely, zero public exposure since.
