MMDM OpenEMR — Offline-First Clinical Platform

Medical Missionaries of Divine Mercy · Houston → Costa Rica · 2024–Present

Self-hosted EMR built to run a six-station volunteer clinic in a Costa Rican parish hall with no internet, no cloud, and no public DNS. Migrated off a corrupted XAMPP environment to a hardened Ubuntu / Apache / MariaDB / PHP stack with a private certificate authority, daily backups, and bilingual Spanish/English clinical forms.
