I will build a fullstack web app with react and csharp net backend
About this gig
Looking for a developer who actually understands both frontend and backend not just someone who copies templates?
I build complete web applications using React (frontend) and C# ASP.NET Core (backend) with PostgreSQL database. Every project includes real authentication, secure API, and clean architecture not just a pretty UI with no logic behind it.
What I've built: ClassConnect a full SaaS EdTech platform with anti-cheating system, AI assistant integration, real-time class leaderboard, role-based access (teacher/student), and secure data storage. Live at classconnect.com.ua
What you get:
React frontend (responsive, modern UI)
C# ASP.NET Core REST API
PostgreSQL database with proper schema
JWT authentication and authorization
Deployment-ready code
Clean, documented codebase
️ Message me before ordering to discuss your project I want to make sure I deliver exactly what you need.
