You will get your SaaS MVP with secure auth, dashboard, and a database
Project details
I build production-ready web apps and SaaS MVPs that stay fast and stable as they grow — not prototypes that break the moment real users arrive.
I'm a full-stack developer and the founder of a small product studio. I work on the MERN / Next.js stack (MongoDB, Express/Node, React) and I've designed and built a full multi-tenant SaaS from the ground up — complete with secure authentication, role-based access control, dashboards, invoicing, and notifications.
What sets my builds apart isn't just that they work — it's that they're built to last: clean database architecture with proper indexing, a real security pass (validated inputs, protected APIs), and performance tuning that keeps load times low. You get software a developer can actually maintain and extend later, not a tangle you'll need to pay someone to rescue.
Tell me what you're building and I'll recommend the right tier — or a custom scope if your idea needs it.

About Marina
Full-Stack MERN Developer | SaaS, Web Apps & E-Commerce
Dhaka, Bangladesh - 10:24 am local time
Most founders don't have a coding problem — they have a "build it right the first time" problem. You've either been handed messy code that breaks as you grow, or watched a quick build turn into months of patching. Either way, the product stalls and so does revenue.
I design and build complete web applications end to end on the MERN stack (MongoDB, Express, React, Node.js). I've shipped real systems across three domains:
- A multi-tenant SaaS platform — role-based access, dashboards, and invoicing, built for full data isolation between organizations.
- A full e-commerce store — secure auth, cart, wishlist, checkout, and an admin dashboard.
- A real estate platform — advanced search and filtering, image management, and a multi-role admin panel.
What I can build for you:
✅ Custom SaaS platforms and MVPs
✅ Admin dashboards and internal tools
✅ E-commerce stores and online platforms
✅ REST API design, development, and integration
✅ Authentication, roles, and secure user systems
✅ Database design and performance optimization
✅ Responsive web apps from your idea or a Figma file
How I work: I tell you the real timeline, not the one you want to hear. I flag problems while they're small, write clean code another developer can actually maintain, and run a security pass on every build — validated inputs, protected APIs, no shortcuts.
Tech stack: React, Next.js, Node.js, Express, MongoDB, MongoDB Atlas, REST APIs, JWT authentication, Redux, Tailwind CSS, TypeScript, Cloudinary, Vercel.
If you're building or scaling a web app and want a developer who treats it like their own, send me a message with a few lines about what you're working on — I'll reply with an honest take on the best path forward.
