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.

Your tools are disconnected. Your team repeats the same manual work every day. Your backend slows down when the system grows. I help fix these problems with reliable automation and backend systems.

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.
