Develop Spiritual Networking App and Website

I want to launch a platform in India that helps users discover holy places, follow respected spiritual leaders and book time with them—all in one seamless experience across web browsers and mobile apps.

The core of the project is a social-network-style environment where people can:
• Search for temples, ashrams and other sacred sites by location or tradition
• Explore public profile pages created by spiritual leaders, complete with photos, teachings, events and live-stream links
• Secure an appointment through an in-built booking system that handles available slots, confirmations and reminders

I will need both the website and the companion Android / iOS apps designed, developed, tested and deployed. A clean, multilingual interface, secure authentication, real-time notifications and an intuitive admin panel are essential for launch.

If you have experience delivering social networking or community apps in the Indian market—especially those that integrate calendars or appointment modules—please outline your recommended tech stack, an estimated timeline for an MVP and examples of similar work.
