You will get MERN & Next.js Bug Fixes | New Features | Fast Support
Project details
You will get bug fixes or new features added to your MERN or Next.js application without breaking your existing system. I focus on clean, safe changes that keep your app stable and running smoothly.
I review your code carefully to find the real cause of the issue. Whether it’s a backend error, frontend bug, or database problem, I fix it the right way so it does not come back.
If you need a new feature, I build it to match your current setup and code style. The goal is to improve functionality while keeping the logic simple and maintainable.
I’ve helped many founders fix production issues and ship features quickly in MERN apps. From API bugs to UI problems, I make sure everything works as expected before delivery.
This service is a good fit if you need fast, reliable help with an existing app. If you are unsure what’s wrong, you can message me first and I’ll guide you before starting.

Job Success
Faisalabad, Pakistan - 6:37 am 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.
