Project details

You will get your backend API issues fixed quickly and reliably.

I specialize in debugging backend systems, fixing API errors, and automating processes using Java and Python. Whether your API is failing, returning errors, or your system is slow, I can identify the root cause and deliver a clean solution.

What sets me apart:
• Strong backend and API debugging skills
• Fast turnaround and clear communication
• Clean, secure, and scalable solutions
• Experience working with real systems in a banking environment

I focus on solving real problems, not just writing code. Every fix is tested to ensure your system works as expected.

If you need a reliable developer who can quickly understand your system and fix issues efficiently, this project is for you.

I fix broken APIs, slow backend systems, and automation bottlenecks fast.

If your system is throwing errors, running slowly, or wasting time on manual processes, I step in and deliver a clean and reliable solution.

What I can help you with:
• Build and fix REST APIs using Java, Spring Boot, Node.js, and FastAPI
• Debug backend issues and resolve errors efficiently
• Automate workflows using Python including Selenium and custom scripts
• Integrate third-party APIs and authentication systems
• Optimize performance and clean up backend code

Relevant work:
• Built an identity verification system with fraud detection and secure API integration
• Developed a backend system for AI-driven health analysis and structured data processing
• Created an emergency response platform with real-time backend communication

I build secure, scalable, and maintainable systems. My experience in a banking environment means I understand reliability, performance, and data security at a high level.

How I work:
• Analyze your system and identify the root cause
• Fix issues or rebuild unstable components
• Optimize performance and code structure
