React & Node BugFixing | Code Debugging

$12/hr Starting at $25

I fix bugs and debug issues in your React and Node.js projects FAST.


WHAT I FIX:

✓ React component bugs (state, hooks, rendering issues)

✓ React Native mobile app issues

✓ Node.js/Express API errors (routing, middleware, validation)

✓ Database query issues (PostgreSQL, MongoDB)

✓ Authentication & authorization problems

✓ API integration issues (third-party services)

✓ Performance bottlenecks (slow components, heavy queries)

✓ Build & deployment errors

✓ TypeScript compilation errors


HOW IT WORKS:

1. You describe the issue & share error logs/code

2. I investigate & identify root cause (not just band-aids)

3. I provide complete fix + detailed explanation

4. We test together to confirm resolution

5. I explain prevention tips for future


MY APPROACH:

✓ Systematic debugging methodology

✓ Root cause analysis (fix the problem, not just the symptom)

✓ Clean, maintainable solutions

✓ Code explanation & learning

✓ Fast turnaround (usually within 24-48 hours)

✓ Proactive communication


EXPERIENCE:

- Production issue resolution at RetailLine (SaaS platform)

- Debugging complex multi-tenant systems

- Performance optimization of bulk processors

- API integration troubleshooting

- React component debugging (state, hooks, rendering)

- Database query optimization


DELIVERABLES:

✓ Fixed code (clean & tested)

✓ Detailed explanation of the issue

✓ Prevention tips for future

✓ Code review if needed


COMMON ISSUES I SOLVE:

✓ "White screen" or blank component renders

✓ API responses not showing up

✓ State not updating correctly

✓ Memory leaks & performance issues

✓ Build errors & compilation issues

✓ Authentication/authorization failures

✓ Database connection errors

✓ Weird edge cases & race conditions


TIMELINE:

- Simple bug fix (obvious error): 2-4 hours

- Medium issue (requires investigation): 4-8 hours

- Complex debugging (system-wide): 8-16 hours

- Can work faster for urgent issues


WHY CHOOSE ME?

✓ Experienced with real-world production systems

✓ Logical, systematic debugging approach

✓ Explains the issue so you understand

✓ Provides solutions, not temporary fixes

✓ Available for quick turnaround

✓ Helps you prevent similar issues in future
