About this gig

Need a fast, secure Node.js backend or REST API built or fixed? I specialize in Node.js, Express, MongoDB, and JWT authentication, whether you need a bug squashed or a full backend built from scratch.

What I can do for you:

  • Build REST APIs with Node.js & Express
  • MongoDB & Mongoose schema design & queries
  • JWT authentication & role-based authorization
  • Fix backend bugs, crashes & server errors
  • API integration with third-party services
  • Middleware, error handling & validation
  • Performance optimization & security hardening
  • Deployment-ready code (clean & documented)

Why clients choose me:

  • Secure, scalable code not spaghetti fixes
  • I document what I build so you understand it
  • 5+ years full-stack experience
  • Fast response & clear progress updates
  • Root cause fixes, not surface-level patches

How to get started: Describe your project or bug, share any relevant code or error logs, and I'll respond with a clear plan within 1 hour.

Please message before ordering so I can confirm scope and timeline.

    Suliman gave me a great experience, definitely will be working again with him. He responded swiftly to updates and changes, tried to understand my needs, and was able to produce exactly what I wanted in the agreed-upon time frame.
