State Management Not Working After Refactoring
After Cursor refactored your state management code (Redux, Context, or other), state changes are no longer reflected in the UI. Components aren't updating when state changes.
The state management integration or store configuration may have been broken.
Error Messages You Might See
Error: Could not find "store" in either the context or props
State is undefined
Action not dispatched
Component not updating
Common Causes
- Store not provided to app via Provider component
- Direct state mutation instead of immutable updates (Redux)
- Action/reducer refactored incorrectly, not returning new state
- Selector function broken after store shape changed
- useSelector/useDispatch hooks removed or context not passed down
How to Fix It
Verify Provider wraps app: <Provider store={store}><App /></Provider>. Use Redux Devtools to inspect actions/state. Return new state objects: return {...state, property: newValue}. Test selectors separately. Add console.log in reducer.

I’ve watched the tech landscape evolve over the last decade—from the structured days of Java Server Pages to the current "wild west" of Agentic-driven development. While AI can "vibe" a frontend into existence, I specialize in the architecture that keeps it from collapsing.
My expertise lies in the critical backend infrastructure: the parts that must be fast, secure, and scalable. I thrive on high-pressure environments, such as when I had only three weeks to architect and launch an Ethereum redemption system with minimal prior crypto knowledge, turning it into a major revenue stream.
What I bring to your project:
Forensic Debugging: I don't just "patch" bugs; I use tools like Datadog and Explain Analyzers to map out bottlenecks and resolve root causes—like significantly reducing memory usage by optimizing complex DB joins.
Full-Stack Context: Deep experience in Node.js and React, ensuring backends play perfectly with mobile and web teams.
Sanity in the Age of AI: I bridge the gap between "best practices" and modern speed, ensuring your project isn't just built fast, but built to last.

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.**

Get HelpFrequently Asked Questions
Why isn't component updating?
Check if you're mutating state directly. Redux requires new object: {...state, x: y}. Use Redux Devtools to verify action fires.
What's a selector?
Function that extracts part of state: const name = useSelector(state => state.user.name). Makes store shape changes easier.
