About this gig

Is your Node.js backend failing, crashing, or blocking payments

and API requests?


Heres what I can do:

  • Debug and fix backend bugs in existing Node.js and Express code
  • Resolve API errors, logic issues, and authentication problems
  • Fix payment or third party integration issues already present
  • Identify the root cause by checking logs and request flow


Experience:

I have 3+ years of experience working on real production backends

and fixing issues that break live systems.


Please message me before ordering so I can review the issue first.

Hi, I’m Shahid, a backend focused developer with hands on experience in building scalable and high performance systems using Node.js and Express. I specialize in API development, performance optimization, Redis caching, JWT based authentication, and asynchronous processing using RabbitMQ. I have worked on production systems handling millions of records and improving response times from seconds to milliseconds. I can support React and Next.js when needed, but my primary focus is building reliable, efficient backend systems.
