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

Production Server & Hosting Issue Resolution

If your live website is down, slow, or misconfigured — I can help. I’ve resolved critical hosting issues on DigitalOcean, Plesk, cPanel, and custom VPS setups.

Server Problems I Solve:

  • PHP version conflicts and redirect loops
  • Apache/Nginx misconfigurations and .htaccess errors
  • MySQL permission issues and database crashes
  • Queue job failures and cron job misfires
  • SSL certificate errors and HTTPS redirection problems
  • SSH access, firewall blocks, and security hardening
