Client: Molina Healthcare, Irving, Tx April 2021 Mar 2023 Role: Sr. React/NodeJS Developer Project Description: The project entails creating a user-friendly appointment platform that enables remote medical consultations. Hospitals register doctors with unique IDs, allowing people to search for and book appointments depending on their specialism. One of the primary problems with the current situation is that hospitals have to deal with a high volume of patients. To keep patients at ease, we created a user-friendly appointment platform that offers medical services and allows users to interact and chat with doctors. Hospitals can register their doctors in the portal using their IDs, and patients can then search for doctors with various specialties for consultations. The intent was to create a basic user interface for the system that individuals of all ages could simply navigate. Both physicians and patients can benefit greatly from this system. The automated method will reduce the amount of manual work that hospital employees must perform. Maintaining patient health records is possible, and these records can be used in medical research.
