I will build a full stack saas web application with frontend and backend
Mahin Anowar
About this gig
Need a Full Stack SaaS Developer who ships, not one who just writes code?
I build complete web applications end to end frontend, backend, database, and deployment. You get a working app on a live URL, not a folder of files.
WHAT I BUILD
- SaaS MVPs, dashboards, admin panels, internal tools, portals
- Frontend: React, Next.js, TypeScript, Tailwind CSS
- Backend & REST APIs: Node.js, Express, Python FastAPI
- Databases: PostgreSQL, MongoDB, Supabase, Redis
- User authentication, roles and permissions, admin access
- Stripe payment integration (Premium)
- AI features chatbots, smart search, automation
- Deployment on Vercel, Docker, CI/CD
WHY ME
I don't just write code I run products. I built and maintain an AI-powered platform used by 3,800+ students, solo. I currently do contract work on a live housing platform (frontend and backend), with my code reviewed and merged by their in-house developer.
HOW IT WORKS
- You send your idea I reply with a written scope, stack and timeline, free
- You approve it before I write a single line
- Regular progress updates plus a live staging link
- Full source code, documented, yours to keep
Message me before ordering. I'll tell you honestly what your project needs.

Hi, I’m Mahin — a full-stack developer with 2 years of experience and a CSE background from North South University.
I build modern, reliable web apps using React, Next.js, Node.js, Python/FastAPI, PostgreSQL, and MongoDB. I created NSU Insights, my own AI platform used by 3,800+ students. I specialize in solving complex bugs, finding root causes, and delivering clean, production-ready solutions. I’ve also contributed fixes to 35+ open-source projects including React Router, ESLint, Axios, Node.js, and Jest.
Have a project or tricky bug? Send me the details — I’ll handle it.

FAQ
What kind of websites can you develop?
I build full stack web apps — SaaS products, dashboards, admin panels, internal tools and customer portals. React/Next.js and TypeScript on the front, Node.js or Python FastAPI on the back, PostgreSQL or MongoDB. Need a landing page only? I have a separate gig for that.
How do we get started?
Message me with what you want to build. I'll send back a free written build plan — the stack, the screens, a timeline and a fixed price. You approve it before I write any code, so we both know exactly what's being delivered.
How long will it take to complete my website?
Basic is 7 days, Standard 14, Premium 21 — and those are real dates, not estimates. I delivered my last project three days early. If your scope needs longer than 21 days, message me first and I'll quote a custom timeline.
Will it work on mobile and tablet?
Yes. Every package is fully responsive across desktop, tablet and mobile — it's built in from the start, not bolted on at the end. You'll get a live staging link during the build so you can check it on your own phone.
Can you add specific features or third-party integrations?
Yes — payment gateways, email services, analytics, storage, auth providers and AI features like chatbots or smart search. Each package includes a set number of integrations; extras beyond that are quoted before we start, never mid-order.
What does your service include, what is not?
Included: frontend, backend, database, user login, deployment, and full documented source code you own. Not included: content writing, logo design, paid subscriptions (hosting, APIs), and app store publishing. Anything outside the agreed scope is quoted separately.
Do you offer revisions?
2 on Basic, 3 on Standard, 4 on Premium. Revisions cover fixing and refining what we agreed in the written scope. Genuinely new pages or features aren't revisions — I'll quote those separately so the price stays honest both ways.
Can you work with my existing design or codebase?
Yes. Send me a Figma file, a GitHub repo, or a site you want extended, and I'll match your existing setup and conventions. I currently do exactly this on a live platform, with my code reviewed and merged by their in-house developer.
How do you ensure website security?
Passwords are hashed, never stored in plain text. Secrets live in environment variables, never in the repo. API routes are protected and access is checked per user role. Inputs are validated server-side. Data travels over HTTPS.
