Full Stack Developer Needed for SaaS Platform Development
Great working with Zubair. He maintained clear and consistent communication throughout the project and delivered the work on time. He has strong skills in React and Node.js and demonstrated good experience in SaaS application development. Zubair also has a solid understanding of database design and management, which helped ensure the system was well structured and scalable. Overall, a reliable developer, and I would definitely work with him again in the future. 👍
About Zubair
Node.js Back-end Developer | Supabase | Next.js | MERN
Gilgit, Pakistan - 7:20 am local time
automation systems that scale with your business.
Hi, I'm Zubair - a Full Stack Developer specializing in scalable
backends, SaaS architecture, and AI integration, with 4+ years of
experience delivering systems that drive measurable business results.
Here's what I've shipped:
- A tourism marketplace now serving 800,000+ active users
- An HR management system that reduced administrative workload by 60%
- Multiple SaaS platforms, REST/GraphQL APIs, and AI-integrated
workflows for startups and growing tech companies
I focus on three areas where I deliver the most value:
SaaS PLATFORMS AND BACKENDS
Full-stack SaaS builds using Next.js, NestJS, Node.js, and PostgreSQL
from architecture design to production deployment. Clean code,
scalable structure, and secure from day one.
AI AND AUTOMATION SYSTEMS
OpenAI and LangChain integrations, n8n automation workflows, and
intelligent backends that reduce manual work and unlock new product
capabilities.
APIs, AUTH AND PAYMENTS
Production-grade REST and GraphQL APIs, OAuth 2.0, JWT authentication,
and Stripe/PayPal payment systems built for performance, security,
and reliability.
TECH STACK
Frontend - Next.js, React, TypeScript, Tailwind CSS, SvelteKit
Backend - Node.js, NestJS, Express, FastAPI, Python, Django
Database - PostgreSQL, MySQL, MongoDB, Redis, Prisma, TypeORM
AI - LangChain, OpenAI, n8n
APIs - REST, GraphQL, WebSockets
DevOps - Docker, CI/CD, AWS, Vercel, Firebase, NGINX
Payments - Stripe, PayPal, JWT, OAuth 2.0
WHAT YOU CAN EXPECT
- Architecture designed for your next 50,000 users, not just launch day
- Clear communication with regular progress updates, zero ghosting
- Honest scoping - I'll tell you what you need, not what sounds impressive
- On-time delivery, or I flag issues early before they become problems
- Code you (or your next developer) can actually maintain and extend
I work best with founders and product teams who have a real problem
to solve and need a developer who thinks beyond the ticket.
Message me with your project details - I respond within a few hours
and offer a free 30-minute discovery call to scope your project properly.
