I will fix bugs in nodejs or laravel applications
Saikat Sen
About this gig
Need a bug fixed in your Node.js, Laravel, or MERN app? I debug backend, frontend, database, and deployment issues, then explain the fix. I'm a senior backend engineer with 5+ years of experience across Node.js, Express, NestJS, Laravel, MongoDB, PostgreSQL, and Redis, and I maintain a live fintech platform serving thousands of users. I can help with API errors, authentication, React state and integration issues, PHP and Laravel bugs, slow database queries, Redis and queue failures, server and deployment errors, and broken Docker or CI/CD pipelines. I trace the issue, confirm the agreed scope, implement the fix, and summarize what changed. Package limits vary by tier. Please message me before ordering with the error, relevant logs, stack, and a short description of what you expected to happen. Do not send secrets or production credentials; share only the code or access needed for diagnosis.

FAQ
What types of bugs do you fix?
I handle Node.js, Express, NestJS, Laravel/PHP, React/MERN, database, Redis, and deployment issues. Share the error and expected behavior so I can confirm the scope.
Can you fix urgent bugs or issues in my live app?
I can take urgent issues when my schedule and the scope allow. Message me with the symptoms and impact first, and I’ll confirm availability before you order.
Will you explain the fix you applied?
Yes. Every package includes a brief summary of the issue and fix. A more detailed findings report or code review is included only where listed in the selected package.
What if the bug is not fixed in my first order?
Each package includes the revisions listed. If the reported issue remains, share the test results and I’ll review it within the agreed scope. New issues or additional work may need a separate order.
