Mansimar was a software developer intern at Mozilla and as part of her internship, developed a PubSub channels based push microservice. She has spoken at FOSDEM 2017 and EuroPython 2017 about the webpush technology and has written a series of articles about her work and webpush technology. She worked on Brew as part of Google Summer of Code 2017 with Homebrew. Previously, she was also an intern with HackerRank. Being an ardent open source enthusiast, she has contributed to Kinto - a minimalist JSON storage service, Brackets - a code editor by Adobe and also has a string of self-projects that she’s proudly maintaining.
