API Rate Limit Exceeded After Changes
After Cursor refactored your API request code, the application suddenly exceeds rate limits and receives 429 Too Many Requests errors. API calls that were working are now being rate limited.
The refactored code may be making redundant requests or not implementing proper batching.
Error Messages You Might See
429 Too Many Requests
Rate limit exceeded
Quota exceeded
Too many requests from this IP
Common Causes
- Removed request caching or memoization
- Loop making duplicate API calls instead of batch endpoint
- Removed debounce/throttle on frequently triggered requests
- Polling interval set too short or continuous
- Retrying failed requests too aggressively
How to Fix It
Implement caching: store responses and return within TTL. Use debounce for search/filter: debounce(fetch, 300). Batch requests to single endpoint. Reduce polling interval. Implement exponential backoff for retries: delay = baseDelay * 2^attemptCount.

Caio Rodrigues
I'm a full-stack developer focused on building practical and scalable web applications. My main experience is with **React, TypeScript, and modern frontend architectures**, where I prioritize clean code, component reusability, and maintainable project structures.
I have strong experience working with **dynamic forms, state management (Redux / React Hook Form), and complex data-driven interfaces**. I enjoy solving real-world problems by turning ideas into reliable software that companies can actually use in their daily operations.
Beyond coding, I care about **software quality and architecture**, following best practices for componentization, code organization, and performance optimization.
I'm also comfortable working across the stack when needed, integrating APIs, handling business logic, and helping transform prototypes into production-ready systems.
My goal is always to deliver solutions that are **simple, efficient, and genuinely useful for the people using them.**

I am a technologist and product builder dedicated to creating high-impact solutions at the intersection of AI and specialized markets. Currently, I am focused on PropScan (EstateGuard), an AI-driven SaaS platform tailored for the Japanese real estate industry, and exploring the potential of Archify.
As an INFJ-T, I approach development with a "systems-thinking" mindset—balancing technical precision with a deep understanding of user needs. I particularly enjoy the challenge of architecting Vertical AI SaaS and optimizing Small Language Models (SLMs) to solve specific, real-world business problems. Whether I'm in a CTO-level leadership role or hands-on with the code, I thrive on building tools that turn complex data into actionable value.

What's debounce?
Waits for pause in activity before executing. Useful for search: only fetch after user stops typing for 300ms.
How do I cache API responses?
Store in variable with timestamp. Check if data is fresh before fetching. Clear on mutation (POST/PUT/DELETE).
