Dailyy App | Social Network
Role:
Founder & Technical Lead of Dailyy
Focus:
Social Network Architecture & Development

Overview

I conceptualized, designed, and implemented "Dailyy," a dynamic social networking platform dedicated to organizing activities, coordinating meetups, and sharing experiences with friends. As the founder and technical lead, I oversaw the entire development process, ensuring a scalable, secure, and engaging solution.

The platform's back-end was built using Node.js, Fastify, and MongoDB to support efficient data handling and real-time interactions. On the front-end, I employed React Native to create an intuitive, mobile-first user interface. Leveraging a serverless architecture enhanced scalability, reduced operational overhead, and ensured smooth performance under varying loads.
