Scalable Event Booking Backend with Payments & Real-Time Chat
I built a scalable backend system for a social event booking platform that enables hosts to create events and guests to discover, join, and interact in real time.
The platform is currently generating over $60K+ in revenue, handling real users, payments, and live interactions.
🚀 Key Features & Contributions:
• Designed a multi-role system (Host & Guest) with secure authentication
• Built complete event lifecycle: creation, booking, participation, and reviews
• Integrated Stripe for payments, including wallet system for hosts
• Implemented payout flow allowing hosts to withdraw earnings
• Handled refunds, disputes, and transaction management
💬 Real-Time Communication:
• One-to-one chat between users
• Event-based chat for participants
• Group chat system for social interaction
• Media sharing (images, voice notes, events, reminders)
📈 Growth & Engagement Systems:
• Followers & following system (social graph)
• In-app notifications, email, SMS, and WhatsApp alerts
• Event promotion and user engagement features
⚙️ Performance & Scalability:
• Optimized backend to handle concurrent users and real-time messaging
• Designed scalable architecture for future growth
• Ensured secure and reliable payment processing
💡 Result:
A production-ready backend powering a live platform with thousands of users and $60K+ revenue, built for scalability, performance, and real-world usage.

🤩 This incredible animation easily demonstrates how the I2C, SPI, and UART communication protocols work.
I2C, SPI and UART are the invisible hearts that keep our interconnected embedded systems and peripherals operating optimally.
1️⃣ I2C (Inter-Integrated Circuit) is a serial communication protocol enabling multiple devices to communicate over short distances. It utilizes a bus system with master-slave communication.
2️⃣ SPI (Serial Peripheral Interface)is a synchronous serial communication interface. It is used for connecting multiple peripheral devices to a microcontroller or microprocessor.
3️⃣ UART (Universal Asynchronous Receiver-Transmitter) is a serial communication protocol commonly used for point-to-point communication between two devices.
