A few projects from over the years. Some are still running, some taught me a lot, most did both.
Video consultation platform, HIPAA compliant
A video consultation product I've been working on at Spring. It uses WebRTC for the calls, and media is stored on S3, Azure Storage, or GCS depending on the client. I rewrote the API layer and tuned the queries behind it, which brought response times down by about 40%. For HIPAA we handle encryption at rest, access controls, and audit logging.
Diagnostic tests, patient and ops portals
A platform for managing diagnostic test bookings. I built the REST API middleware and rewrote a lot of the SQL behind it to get better throughput. There are two portals, one for patients booking tests and an internal one for the team managing them.
Education platform with affiliate tracking
An education platform with affiliate tracking, lead management, and self-serve enrollment. I wired up Stripe for recurring subscriptions and invoice generation.
Vehicle rental marketplace
Built end-to-end on the Zend framework over a LAMP stack. Search, booking, inventory, and payment — the whole thing.
Clinical operations system
A multi-module system with role-based access for doctors, nurses, and admin staff. I set up SMS triggers for appointment reminders, which helped bring patient no-shows down.
