// How to build Live 1:1 Tutoring Platform for K-12 Students
The Indian K-12 tutoring market is $10B+ and shifting online post-COVID. A two-sided marketplace needs a solid booking engine, reliable video (100ms is the best-priced WebRTC SDK for India), and a shared whiteboard. PostgreSQL handles scheduling with timezone-aware timestamps; NestJS manages the complex session lifecycle (booking, reminders, live, review, payout). Parent dashboards drive retention.

## What to build in the MVP
—Tutor profile, subject tags and availability calendar
—Student search, filter and instant / scheduled booking
—Live video session with shared whiteboard (Excalidraw)
—Session recording stored to S3 for 30-day replay
—Automated tutor payout via Razorpay Route
—Parent dashboard with session history and progress notes

## Engineering risks to plan for
!100ms charges per minute of video — model the cost at 50k monthly sessions before launch or margins will surprise you.
!Scheduling across IST + other time zones needs UTC storage with display conversion; bugs here erode tutor trust fast.
!Razorpay Route requires a separate KYC process for marketplace payouts — start it in week 1.
