During my time as a Full Stack Developer at SMC National, I led the development of a HIPAA-compliant lead-to-patient tracking application. We started with PHP and MySQL but later switched to Node.js, Express, and MongoDB for better scalability.
In this project, we built essential features like a secure Multi-Factor Authentication (MFA) login system with Twilio and Sendgrid for SMS and email verification, XLSX record import/export, and efficient management of large datasets, exceeding 35 million records. We also implemented real-time Delta Syncs for processing 10,000+ records daily, Webhooks for data handling, and data visualization using Apex Charts and Datatables.
We automated tasks with Cron Jobs, improved performance with a caching system, and established a near real-time Lead to Patient Matching system. Secure communication was ensured through JWT/Session permission management and Socket.IO, and we seamlessly integrated with over 15 Patient Management Systems for efficient data retrieval.
