I will build a full stack web application or saas platform with nextjs
Samuel Mwanga
About this gig
Need a web app that actually works in production, not just a pretty prototype? I build full-stack web applications and SaaS platforms from idea to deployment.
WHAT I BUILD
- SaaS platforms and MVPs
- Client portals and booking systems
- Admin dashboards and internal tools
- Marketplaces and membership sites
- Business websites with a real backend
WHAT'S INCLUDED
- Next.js + React + TypeScript frontend
- Backend APIs (Node.js or Laravel)
- PostgreSQL or MySQL database with Prisma
- Login, user roles and permissions
- Payments: Stripe, PayPal, M-Pesa and mobile money
- Responsive, fast, SEO-ready pages
- Deployment to Vercel, VPS or your cloud
- Clean source code in your GitHub repo
WHY ME
I founded NinoPOS, a live SaaS point-of-sale platform, so I know what it takes to run real users, real data and real payments, not just demos.
Message me with your idea before ordering. I'll confirm scope, stack and timeline so you know exactly what you're getting.

I'm a full-stack developer building SaaS platforms, business websites and custom systems: POS, ERP, inventory, invoicing, CRM and admin dashboards.
I work in Next.js, React, TypeScript, Node.js, PostgreSQL and Prisma, plus Laravel, PHP, Vue, MySQL and WordPress, covering frontend, backend, auth, APIs and deployment.
I founded NinoPOS, a point-of-sale platform for African businesses, and run Primezone Web Host in Dar es Salaam. I build production-ready systems, not mockups.

FAQ
Which tech stack do you use?
Mostly Next.js, React, TypeScript, Node.js, PostgreSQL and Prisma. I also build in Laravel, PHP, Vue and MySQL when that fits your project or existing code better.
Do I own the source code?
Yes. You get the full source code in your GitHub repository, and everything I build for you is yours.
Can you deploy and host the app?
Yes. I deploy to Vercel, a VPS or your cloud account, and I can also host it on my own company, Primezone Web Host.
Can you integrate M-Pesa or mobile money?
Yes. I integrate M-Pesa, Tigo Pesa and Airtel Money, as well as Stripe and PayPal for card payments.
What do you need to get started?
A description of your idea, the main features, any designs or reference apps, and your timeline. If you don't have designs, I can build a clean UI for you.
Do you offer support after delivery?
Yes, 30 days of bug-fix support. After that I offer monthly maintenance or per-task work.
