About Me

Get to know me!

Hi, I'm Melvin He, from Massachusetts! I enjoy solving challenging problems, and I do it with the use of code! I'm a junior at Brown University, where I'm studying Computer Science. In particular, I love working with AI and Systems, and I do a bunch of Full-Stack development too.

Besides coding, some of my other passions are the following:

  • Brown CSA : I'm a current Family Head for Brown's Chinese-American Students Association where we hold events and panels to introduce Chinese culture to members of the Brown community!
  • Sports: Whether it's watching or playing, you can catch me cheering on the Celtics and Boston teams, or playing a quick pick-up game of football, tennis, or basketball!
  • Hobbies: Some of my other hobbies include scenic biking & hiking, playing Super Smash Bros & board games with friends, and learning a new recipe/dish to cook (and eat)!

Software Engineer Intern @Fidelity Investments

June 2023 - August 2023

  • I worked on an agile development team to migrate Fidelity Institutional's JSP-based website to Angular with Sitecore as a CMS, contributing to ETF bricklet design, RESTful API development, Jenkins & Terraform CI/CD pipelines, cloud architecture, and unit/integration testing.
  • Through rotational roles, I also developed APIs for SwiftUI blockchain app for Fidelity Labs (Fidelity's startup incubator) as well as assisted with quantitative equity trading and UI/UX platform design with Fidelity Capital Markets (Fidelity's innovative trading arm).
