Bug Fixing for Laravel & MERN Stack Applications
Whether your app is built with PHP Laravel or the MERN stack (MongoDB, Express.js, React.js, Node.js), I can quickly identify and fix bugs that affect performance, security, or user experience.
Common Issues I Fix:
- Laravel route errors, controller bugs, and Blade template issues
- Broken API endpoints or failed integrations (Stripe, Twilio, Google Calendar)
- React component crashes, state management bugs, and UI glitches
- Node.js server errors, Express routing issues, and MongoDB query failures
- JavaScript console errors and slow page rendering
- Form validation problems and data submission failures
- Payment gateway failures and transaction issues
- Authentication and session handling bugs
My Approach:
- Deep code inspection and error tracing
- Live debugging and testing in staging or production environments
- Clean, documented fixes with version control (Git, GitHub, Bitbucket)
- Post-fix validation to ensure stability and performance
