National dental support

Full-stack Developer

Jan 2024Jun 2024 · 5 mos · Virginia, United States · Remote

  • As a Full Stack Developer contracted by National Dental Support (NDS), I spearheaded the development of Sync Engage, an innovative solution designed to streamline the processing of dental claims from over 1000 dental offices nationwide. Leveraging a robust tech stack including React, Node.js, Express, and MongoDB, I engineered a scalable and efficient system capable of synchronizing vast volumes of data into a centralized repository.
