You will get MERN & Next.js Bug Fixes | New Features | Fast Support
Rising Talent
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 - 8:56 pm local time
I’m Abdul Hanan, a backend engineer and automation specialist. I build n8n workflows, API integrations, and Node.js/NestJS systems that connect tools, reduce manual work, and keep business operations running smoothly.
Recent work includes a high-traffic quiz platform serving millions of users and connected with 40+ external websites. I also built an enterprise-level NestJS backend with Redis caching, BullMQ queues, Firebase notifications, webhooks, rate limiting, and clean error handling.

n8n automation workflows for data entry, reporting, alerts, and follow-ups
API integrations between CRMs, payment systems, and internal tools
Node.js and NestJS backend systems with authentication, validation, and secure APIs
Webhook-based systems for real-time updates and event tracking
AI-powered workflows using OpenAI and GPT for support, lead handling, and document processing
Zapier to n8n migrations for teams that need more control and lower costs
𝗪𝗵𝘆 𝗰𝗹𝗶𝗲𝗻𝘁𝘀 𝘄𝗼𝗿𝗸 𝘄𝗶𝘁𝗵 𝗺𝗲
Many freelancers can connect two apps in Zapier or n8n. I go deeper than that. I think about queues, caching, error handling, webhook retries, logs, and the backend logic behind the workflow.
That is the difference between an automation that works in a demo and one that runs safely in production. My goal is to build systems that are simple to use, easy to maintain, and strong enough to grow with your business.

If manual work, broken workflows, or weak integrations are slowing your team down, send me your current process. I’ll tell you clearly whether automation can fix it or whether the backend needs to be improved first.
