Vivek Vellaiyappan’s Technical Achievements (few among many he is proud of)

• Saved $1.18M annually at Tesla. Vivek, as a Full Stack Developer/Data Scientist Intern developed a real-time web app which reduced the employee headcount from 7 to 3 in General car assembly line. The app logs issues faster than the typical system they were using. Because of this, more data being logged which in turn gave more data insights to make data driven decisions. It is now used in GA3, EOL and discussions going on to use this on China Gigafactory. The app is heavily adopted and replacing the typical one they were using prior. (Calc: if $35 per hour is GA line technician Salary, then for 4 (members) * 35 $/ hr * 24 hr/day * 350 days/year = $1.18M annual).
• During his Express scripts internship, Vivek built the foundation of the company’s official Developer portal website which will be exposing the approved sensitive APIs information to external or internal clients. He self learned a new WCM platform language, Drupal within a short span of time to build the foundation. He thrives to master software architecture and have huge interest over it too. He had an amazing opportunity to shadow senior architects at ESI to learn the best architectural patterns and participate in the architectural road map strategies too.
• Vivek loves to improve his team’s working efficiency. At Athenahealth, he created an UI tool for his team to update the Database settings easier in UI rather than frequent manual query typing. At Marist College, as a Full Stack Developer, he developed a dashboard to automatically send email to the recipients every morning based on the workshop information instead of them manually sending those email daily.
