You will get a production-ready SaaS web app (React + Node)
Top Rated
Project details
I've spent 5+ years building web applications that people actually use — not just code that works on localhost and breaks in production. From a 30-app enterprise ecosystem serving millions of users (PaintNite/Yaymaker) to a SaaS platform generating $60K/month in revenue (Vonza), I build things that matter.
I don't just write code — I think about your product. Before touching a single line, I understand your business, your users, and what success looks like. Then I design architecture that won't fall apart when you scale from 100 to 100,000 users.
My stack: React/Next.js frontend, Node.js/NestJS backend, PostgreSQL, and AWS. I've shipped production systems with Stripe payments, real-time WebSockets, multi-tenant architecture, and AI integrations — not side projects, but products serving real customers.
What you get that most freelancers won't give you:
— Clean, documented code your next developer can actually read
— Weekly demos so you're never in the dark
— Architecture that scales with your business
— Honest communication — if something won't work, I'll tell you early
Send me a message — no commitment, just a real conversation about what you need and whether I'm the right fit.

Web Developer – Subscription Portal (Stripe + Supabase Integration)
Went far and beyond the expectations that were set: in fact, he did such a stellar job that we continued on for a few months on additional backend work and additional features, and we continue to roll out to my users. Not only was he able to answer my questions, but he provided detailed feedback and resolutions to additional projects that we added on. I was more than happy to work with him, and for any other future development, we will definitely be bringing him back on for our projects.

Stripe Credit and ACH Payment Links
This is my second time working with Zohaib on a similar project, and would happily work with them once again in the future!

Experienced developer required to create custom code to send survey data to ConvertKit using API
We had a kind of gnarly project with a clear desired outcome but a complicated middle. Zohaib understood all the necessary pieces and now to put them together for a well-designed and functioning widget that we can continue to adapt as needed for our always evolving products. He's an excellent communicator, friendly, helpful and quite adaptable to our frenetic schedule and thinly stretched attention. Hire him!

Need Full Stack MERN Dev w/ knowledge AWS/Amplify/Twilio/Apify
⭐⭐⭐⭐⭐ Finally, a team that gets it
After getting burned by a few big offshore shops with too many PMs and not enough actual progress, working with this team has been a breath of fresh air.
They jumped right in on our MERN stack and just... got things done. Clean code, minimal QA headaches on our end, and they're actually online during our PST hours when production issues pop up. No more waiting 12 hours for a Slack reply.
They work quickly using the latest AI tools, and know API's inside and out, and they handled our Twilio, Apify, Stripe, and Salesforce integrations without needing their hands held. Communication in English has been excellent across the whole team.
Honestly, if you've been frustrated with offshore agencies that overpromise and underdeliver, give these guyt a shot. We're sticking with them and are working on ongoing projects.
Highly recommended. 🙌

Job Success
Sialkot, Pakistan - 9:19 am local time
I've earned $300K+ on Upwork across 100+ jobs and 3,400+ hours of web development work with a 100% Job Success Score, and I'm a Top Rated Plus full stack developer in the top 3% on the platform. As a SaaS Developer I've shipped 20+ production SaaS platforms with live users and real revenue, and I modernized and maintain 30+ interconnected Node.js applications for PaintNite on multi-cluster Kubernetes. My work as an AI SaaS Developer is in production today, not in demos: RAG pipelines, AI chatbots, and AI agents running inside revenue-generating products.
"Finally, a team that gets it" — client review on an $18K, 855-hour full stack React Node project.
WHAT I BUILD AS A FULL STACK DEVELOPER
AI SaaS products and AI integration — As the AI SaaS Developer teams hire when prototypes aren't enough, I ship production RAG pipelines, AI chatbots, and AI agents — applied artificial intelligence and machine learning on Node.js and Python backends inside revenue-generating platforms — using OpenAI, Claude, AWS Bedrock, Cohere embeddings, and Google Vertex AI. GovDoc.ai: a multi-tenant RAG system turning federal contracting PDFs into 50+ extracted data points with semantic search. Patrol6: AI-powered video incident analysis inside an enterprise IoT security SaaS.
SaaS platforms and MVPs — As a SaaS Developer I handle end-to-end SaaS development — from database schema to Stripe billing to production monitoring. Vonza alone includes a course builder with LMS, website builder, sales funnels, e-commerce, email marketing, and CRM — architected end to end as a Full Stack Developer on multi-tenant Node.js microservices. If you need a SaaS Developer who has already made the mistakes on his own product, that is the experience Vonza bought me.
React and Next.js frontends — I build Next.js dashboards, Next.js admin portals, and multi-tenant component libraries — production web application work, including AI interfaces in React: chat UIs, streaming responses, and AI-powered analytics. I led the full React 16 to Next.js 15 / React 19 / TypeScript modernization across 30+ live PaintNite applications, and I work daily with the Next.js App Router — server components, streaming SSR, and edge middleware. Under the hood that means modern JavaScript, semantic HTML5, and maintainable CSS, not framework magic.
Backend and APIs — As a Node.js Backend Developer working in NestJS and Express, I design authentication, business logic, background jobs, and APIs (REST, GraphQL, tRPC) built to scale, with PostgreSQL, MongoDB, MySQL, DynamoDB, Supabase, and Redis — API integration with Stripe, PayPal, Twilio, HubSpot, SendGrid, Mapbox, and 25+ third-party services. I also take on PHP and Laravel work when a project needs integration into an existing PHP system — my team at Innovation Insight delivers both.
React Native mobile — Three production apps live on the App Store and Google Play with in-app purchases, push notifications, and offline-first architecture. I own both the mobile frontend and the Node.js APIs powering it.

HOW I WORK
I respond within hours during business days. I send proactive status updates. I flag risks early instead of at the deadline — if something in your spec will cost you money down the line, I tell you before we start, not after. I run a small senior team at Innovation Insight and take ownership of the full-stack development end to end. No hand-offs, no disappearing after onboarding.
Message me with your project details. Within one business day you'll get a real estimate, a suggested approach, and 2–3 relevant examples from my portfolio — whether you need a Full Stack Developer for long-term product work, an AI SaaS Developer for your next launch, or a React Node team to take over an existing Next.js or Node.js codebase.
