Frontend/Full Stack Software Development / Medical Device R&D

I worked in medical device R&D for three years, and I successfully launched a cardiovascular implant that saves lives. However, the medtech industry was falling behind in adopting new technologies so I decided to take it upon myself to pivot and take up a tech stack so that I may take part in modernizing healthcare and medical devices from the tech side.

JavaScript NERP stack: Node, Express, React, PostgresSQL
