Infinite Loop Causes App Hang
After Cursor refactored your component code, the application hangs or becomes unresponsive. useEffect or state updates are causing infinite loops that never terminate.
A circular dependency or missing condition is causing the loop.
Error Messages You Might See
Maximum call stack size exceeded
App becomes unresponsive
Browser tab crashes
Warning: setState from render
Common Causes
- useEffect updates state that's in dependency array, triggering itself again
- Dependency array missing, useEffect runs every render, updating state
- setState called unconditionally in render path
- React.StrictMode double-mounting triggering loop detection
- Recursive function call with no base case
How to Fix It
Add dependency array to useEffect: useEffect(() => { ... }, [dependency]). Prevent setState in render. Break loops with conditions: if (condition) setState(). Use React DevTools Profiler to detect loops. Check browser console for errors.

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’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.

Get HelpFrequently Asked Questions
How do I find infinite loops?
Check React DevTools console warnings. Look for setState calls in effect dependencies. Add console.log to trace.
What's a good dependency array?
Include all values used in effect. If effect updates a dependency, use ref or separate effect. Never omit to 'fix' issue.
