FAQ
Can you build a complete full stack website from scratch?
I build full stack websites from scratch using reactjs, nextjs & nodejs. I handle frontend, backend, database & deployment. Message me with your project for a clear plan.
What tech stack do you use for custom web applications?
I use the MERN stack — MongoDB, expressjs, reactjs & nodejs — or nextjs for SEO-friendly full stack websites. PostgreSQL for databases. Every project is clean, scalable & production-ready.
Do you build web apps with API integration and backend?
Yes — I build REST APIs using nodejs & expressjs, connect third-party services, set up payment gateways & admin panels. Available in Standard & Premium packages.
What is included in your full stack website packages?
Basic: 3-page reactjs/nextjs site. Standard: 7-page business website with API integration. Premium: full stack web app with nodejs backend, admin panel, database & payment gateway.
Can you redesign or rebuild my existing website?
Yes — I rebuild outdated websites into modern full stack websites using reactjs, nextjs & nodejs. Share your URL and I'll give you an honest review & clear rebuild plan.
Will my website be mobile-friendly?
Yes! Every reactjs and nextjs website I build is fully responsive — desktop, tablet and mobile — using modern frontend frameworks and clean scalable code.
Can you integrate third-party APIs into my project?
Yes, as a full stack developer, I integrate RESTful and GraphQL APIs to connect your site with third-party tools such as CRMs, payment gateways, or AI services — perfect for AI-based websites and custom web apps.
Will I get the complete source code?
Yes, you will receive full source code with documentation — complete ownership, easy to maintain and scale your web app or SaaS platform.
How long does it take to build a full stack web app?
Basic reactjs/nextjs website: 2-4 days. Standard business web app with API: 5-7 days. Premium full stack SaaS platform with nodejs backend: 7-10 days. Timeline depends on scope — message me with details for an accurate estimate.

It was a small task but Mustafa has done with complete honesty. It required some code refactoring which was not a part of a deal but he has shown full commitment. Already, hired him for a next job!
