I started in healthcare IT, where downtime isn't an inconvenience, it stops clinics from treating patients. That environment taught me to design for reliability first: segmented networks, hardened firewalls, tested backups, and documentation someone else can actually follow.
At Taj Medical Center I owned the full stack: five VLANs connecting PACS, NAS, lab machines, Avaya telephony and every endpoint in the building. When the facility hit a vendor lock-in crisis during an HMS migration, I extracted the proprietary database myself, restructured the data, and handed a clean dataset to the incoming team on time, at no extra cost.
Now I build the other side of it: cloud infrastructure on AWS and GCP, workflow automation, and custom applications that remove the manual work teams shouldn't be doing. Same instinct, newer tools.
