Back to original languageAbout Nhat Tai
With an engineering background, formerly a doctor in NanoPhysics, I retrained as a fullstack web developer in Ruby on Rails after an intensive bootcamp at Le Wagon Lyon. I worked for nearly a year at Artoche SAS to evolve their web application for managing quotes and invoices for building tradespeople. Available from July 2020 after the end of my contract, I am looking for new opportunities to boost my technical skills and career.
