Dec 2022 – Jun 2023 · 6 mos · Noida, Uttar Pradesh, India

Worked on creating a Referral System which incentivizes users who join the platform with an existing user’s referral code This is expected to have 45% more user registrations on the platform. Used React for frontend and Nodejs for backend and MongoDb for database.
Developed a 2-factor authentication system that logs the user only if he provides the generated OTP (sent over mail) and current password. This secures the system as even if the password is leaked, email puts a second of authentication.
Worked on creating an npm package that was used across different projects using Nodejs.
Implemented a captcha on the user login and registration process to prevent bot interference with the platform.
