ClosFrends

Overview

ClosFrends is an internal DevCore Labs project — a modern social networking platform built with Next.js. The platform is designed for close-knit social circles, focusing on privacy and meaningful connections rather than public broadcasting.

The Challenge

We wanted to explore building a social platform from scratch that prioritizes private sharing over public feeds. The technical challenges include real-time messaging, media handling at scale, and building a feed algorithm that surfaces relevant content from small networks.

Our Approach

The frontend is built with Next.js and React with a focus on real-time interactions. The backend uses Express.js with TypeScript for type safety across the stack. The architecture is designed to scale — separating concerns between content delivery, real-time communication, and media processing.

Technical Breakdown

Next.js App Router with server and client components optimized for different page types. Express.js backend with TypeScript for end-to-end type safety. Real-time communication layer for messaging and notifications. Tailwind CSS for rapid UI iteration during the design phase. Vercel deployment with edge functions for personalized content delivery.

Key Features

• Private sharing within close friend circles
• Real-time messaging and notifications
• Media sharing with automatic optimization
• Personalized feed algorithm
• Privacy-first architecture
• Cross-device responsive experience

Results

Currently in active development. This project serves as both a product and an internal engineering exercise for DevCore Labs.
