You will get REST API Development | Node.js | Express | NestJS Integrations
Project details
You will get fast and secure REST APIs built using Node.js, Express, or NestJS. I focus on clean code, strong validation, and endpoints that work exactly as your app needs.
I can build new APIs, add integrations with third-party services, or improve an existing backend. This includes database connections, authentication, and well-structured endpoints that are easy to use and maintain.
I take extra care with error handling, input validation, and security so your system stays stable and safe. Performance and clarity are always a priority, especially for production systems.
I’ve helped founders build reliable API layers that support growing applications. You’ll receive tested endpoints, clear documentation, and code that is ready to deploy.
This service is a good fit if you need a solid backend foundation or clean integrations. If you’re not sure what your API needs yet, you can message me and I’ll guide you before starting.

Faisalabad, Pakistan - 8:44 pm local time
I build AI automation and backend systems using n8n, APIs, and Node.js that save time and keep your operations running smoothly.
I’m Abdul Hanan, a backend-focused engineer working with Node.js, NestJS, and workflow automation. I design systems that connect tools, handle workflows, and run reliably without constant checking.
Recently, I built an enterprise NestJS backend with strong security, validation, and rate limiting. I’ve also created automation workflows that replace hours of manual work using n8n and API integrations.
What I help you build:
✔ AI automation workflows using n8n
✔ API integrations and backend systems
✔ Workflow automation to remove repetitive tasks
✔ SaaS backends and internal tools
✔ AI-powered features using GPT and automation logic
I don’t just write code. I design systems that work every day.
That means fewer manual tasks, faster operations, and a setup that scales as your business grows.
I’ve also mentored 100+ students worldwide in MERN and n8n, so I build clean systems and explain things clearly.
If you have a workflow problem or want to automate your backend, send me a message. I’ll suggest the best way to build it.
