This project aimed to digitize the process of DAK management for increased transparency and efficiency internally in the Jaipur Collectorate. I built the complete set of REST APIs for the portal by following layered approach for easy maintenance, developed authentication schemes and logic for extensive calculations and ensured proper handling of errors and edge cases for both frontend and backend. Designed and implemented the portal under the guidance of the Deputy Collector of Jaipur. Received a 'Letter of Appreciation' from District Magistrate of Jaipur.
