Modulus prepares people for interviews in consulting, product, finance and other non-tech roles, with cohorts, mentorship, live sessions and peer practice.
As its frontend engineer I built the product from the first screen: the pages that sell a program, booking and payment, scheduling with a mentor, and live sessions with chat beside the stream.

What I built
The product, from the first screen
47 routes, from the first page a visitor sees to the session they booked.
Cohorts and programs
The pages that sell and run them, with every filter kept in the URL.
Razorpay booking
Enrollment paid with credits or card, with verification left to the server's webhook by design.
Scheduling
Sessions booked through Cal.com without leaving the product.
Live sessions
HLS streams with Firebase chat running beside them.
Fast, and measured
Code split by route, and PostHog funnels so the team could see where people dropped off.
