Tutor Booking App & Website

I want to build a seamless platform—mobile app (iOS and Android) plus a responsive website—where students can quickly search for qualified tutors, see real-time availability, and confirm a booking in just a few clicks. Core flow is simple: search ➜ compare profiles ➜ select time slot ➜ pay ➜ receive confirmation. Everything on both the web and the app must stay in perfect sync through a single backend.

Key functions I have in mind
• Robust search with filters (subject, price, level, location, language).
• Individual tutor pages showing bio, credentials, ratings, calendar, and messaging.
• Secure booking and in-app payment (Stripe or similar).
• Automated notifications and calendar sync for both parties.
• Admin dashboard to verify tutors, manage disputes, issue refunds, and pull analytics.

Tech is flexible, yet I lean toward a modern stack such as React / React Native or Flutter paired with Node.js, Django, or Laravel and a scalable database (PostgreSQL or MongoDB). Clean, well-documented API endpoints are essential because I plan future integrations.

Please attach a detailed project proposal outlining:
1. Architecture and chosen tools
2. Milestone breakdown with timelines
3. Feature list mapped to each milestone
4. Post-launch support plan

I will review proposals primarily on clarity of approach, past builds of comparable complexity, and realistic timelines. Strong UI/UX sensibility and secure coding practices are non-negotiable.
