Project details

Already have a web app but want to add AI to it? I will integrate one OpenAI-powered feature into your existing Next.js or Node.js application built properly for production, not a quick hack.

Whether you need text summarisation, content generation, a smart assistant, or a classification workflow, I will design the prompt, build the backend endpoint, connect the frontend, and hand you clean documented code.

Lahore, Pakistan - 9:33 am local time
Top Rated, 100% JSS. I build SaaS platforms and AI-powered web apps for startups. 30+ shipped products. 4 active clients right now. My team and I deliver on Next.js, Node.js, React, and OpenAI. Message me with your project for a free assessment.


I am a Top Rated Full-Stack Developer with a 100% Job Success Score, currently engaged with 4 active clients on live SaaS and web platforms. I specialise in Next.js, Node.js, PostgreSQL, and OpenAI API integrations building systems that are structured to scale from day one.


What I have delivered for recent clients:
1. Built a full SaaS platform with JWT authentication, role-based dashboards, and Stripe subscription billing delivered production-ready within the agreed timeline.
2. Integrated OpenAI API into a live business workflow, replacing a manual process with an automated pipeline that now runs without human intervention.
3. Refactored an existing MERN codebase, improving performance and maintainability while reducing ongoing bug frequency.
4. Architected a multi-module PostgreSQL backend with versioned API design, allowing parallel client feature development without schema conflicts.
5. Delivered a pharmacy delivery platform and an AI-powered lesson planning tool both shipped to production with full backend, authentication, and frontend integration.


My working style:
I send daily progress updates, flag blockers before they become problems, and I do not disappear mid-project. I work best on structured builds MVPs, SaaS platforms, and AI feature integrations where clarity, scalability, and clean code matter.

If you are building an MVP, scaling an existing product, or adding AI to a real workflow, send me a brief description of your project.

I will respond within 4 hours with a clear technical approach.
