JeffLS Connect

A full-stack social media platform built with the T3 Stack, featuring authentication, user profiles, social interactions, real-time content feeds, and end-to-end type-safe APIs.

The project was developed to demonstrate modern full-stack software engineering practices using TypeScript, Next.js, Prisma, and tRPC while exploring the architectural patterns commonly used in social networking applications.

---

Project Overview

JeffLS Connect simulates a modern social media platform where users can create profiles, interact with content, build connections, and engage with a dynamic community feed.

The application leverages the T3 Stack to provide end-to-end type safety across the frontend, backend, database, and API layers while maintaining a scalable and maintainable architecture.

Engineering Highlights

Full-Stack Architecture

Designed and implemented a complete social platform spanning frontend interfaces, backend services, authentication systems, database models, and API communication layers.

End-to-End Type Safety

Utilised tRPC and TypeScript to provide fully type-safe communication between frontend and backend systems, reducing integration errors and improving maintainability.

Relational Data Modelling

Designed database schemas using Prisma ORM to support users, profiles, posts, social interactions, and future platform expansion.

Authentication & User Management

Implemented secure user authentication and account management workflows to support protected content and personalised user experiences.

Scalable Component Architecture

Built reusable React components and modular application structures to support future feature development and maintainable code organisation.

Why I Built This Project

Social media platforms combine many of the challenges encountered in modern software development, including authentication, database relationships, user-generated content, scalable APIs, and responsive user experiences.

This project was built to strengthen my understanding of full-stack architecture while exploring how modern social applications manage data, users, and interactions through a type-safe development workflow.

The application demonstrates practical experience with technologies and patterns commonly used in production SaaS products and large-scale web applications.
