I will build custom ai middleware and secure API integrations with fastapi

In 2026, simply connecting an API is not enough. Direct frontend-to-LLM calls are a security nightmare and impossible to scale. If you want a production-ready AI application, you need a Robust Middleware Layer that handles the heavy lifting between your users and the AI models.

I build high-performance AI Backends and Custom Middleware using FastAPI and Node.js. My systems act as a secure gateway, ensuring your application stays fast, costs stay predictable, and your API keys remain hidden from the world.

Why Your Business Needs This:

• Cost and Rate Control: I implement advanced Rate Limiting to prevent expensive overages and 429 errors.
• Bulletproof Security: Your API keys are never exposed. I use secure vaulting to protect your credentials.
• Data Transformation: My middleware cleans and validates data, reducing token waste and improving quality.
• Ultimate Scalability: Built on asynchronous architectures, your backend will handle thousands of concurrent requests.

I focus on Error Propagation Handling, Caching Strategies to save you money, and Async Task Queues for background processes.
