Project details
🛠️ Backend Error Fixing & Performance Optimization
I help identify and resolve issues in Django and FastAPI applications, ensuring your backend is stable, secure, and high-performing.
🚀 What I Can Do:
🔧 Debug and fix backend errors, bugs, and API issues
⚡ Optimize performance using Redis caching and asynchronous processing
🗄️ Design, optimize, and manage databases: PostgreSQL, MySQL, MongoDB, Firebase
🔄 Build and improve real-time systems using WebSockets
🔒 Implement secure authentication (JWT, OAuth2) and proper access control
📈 Improve scalability and system architecture for growing projects
🧪 Test and debug APIs using tools like Postman and automated testing approaches
🐳 Assist with deployment, Docker setup, and server configuration
💡 I don’t just fix issues — I analyze the root cause and improve your backend for long-term stability, performance, and scalability.
⚙️ Tech Stack:
Python, Django, FastAPI, DRF, Redis, PostgreSQL, Docker, REST APIs
🚀 Let’s Work Together
If your backend is slow, buggy, or needs improvement — I’m here to help you make it fast, reliable, and production-ready.
