About Kamran
Backend Node.js Developer | SaaS, React, Multi-Tenant APIs & AWS
Lahore, Pakistan - 11:13 am local time
With over 4+ years of hands on experience, I have worked on SaaS platforms, insurance systems and real estate applications where performance, reliability and maintainability are critical. My focus is not just writing code but building production ready systems that deliver real business value.
☑ What I can help you with:
• Full Stack Development using React, Next.js and Node.js
• Scalable SaaS and multi tenant application architecture
• Clean and efficient REST API development
• Secure authentication systems including JWT, session based auth and SSO
• AI powered features using OpenAI, Azure AI Search and modern LLM integrations
• Payment gateway integration with Stripe and Chargebee
• Performance optimization and backend bottleneck resolution
• Cloud deployment on AWS with CI CD pipelines
• Pixel perfect UI development from Figma or Webflow designs
☑ Tech Stack and Tools:
🗸 Frontend technologies include React.js, Next.js, TypeScript, Tailwind CSS and Material UI.
🗸 Backend expertise includes Node.js, Express.js, microservices architecture and API design.
🗸 Databases include MongoDB, PostgreSQL and MySQL.
🗸 Cloud and DevOps tools include AWS EC2, Amplify, Docker, GitHub Actions, PM2, Vercel and Netlify.
I also work with modern AI development workflows such as retrieval augmented generation, semantic search, vector databases, prompt engineering and AI driven automation to build smarter applications.
Recent work includes building a multi tenant asset tracking platform, developing insurance systems with complex pricing and payments, creating real estate platforms with scalable APIs and integrating AI powered search systems.
My approach is simple clear communication, clean maintainable code and a strong focus on delivering results that actually matter. I aim to build long term partnerships and support products beyond initial development.
