About this gig
Have an app idea but need someone who can build the whole thing, not just a page? That's what I do.
I'm Sonjoy, a full-stack developer with 6+ years of experience and 250+ projects delivered for clients in the USA, UK, Europe, and Asia. I handle everything: the interface your users see, the backend that powers it, and the database behind it.
What I build:
- SaaS platforms and customer portals
- Admin dashboards with charts and analytics
- E-commerce systems with cart, checkout and orders
- Booking, RSVP and management tools
- AI features like chatbots and smart assistants
How I work:
I use Next.js or Astro with TypeScript, Node.js and MongoDB or PostgreSQL. Login, user roles, secure APIs and SEO are built in from day one. You get clean, commented code that you fully own.
Recent work includes an AI resume analyzer with 500+ beta users, an AI finance dashboard, and an e-commerce platform scoring 95+ on Lighthouse.
Before ordering, message me a short note about your idea. I'll tell you honestly which package fits.
Let's build it properly.

FAQ
What exactly do you build in a full stack web app?
The frontend, backend, database and APIs, all connected. Depending on your package that includes login, user roles, an admin dashboard, payments and AI features.
Which technologies do you use?
Next.js or Astro with TypeScript on the frontend, Node.js/Express on the backend, and MongoDB or PostgreSQL for data. I pick what fits your project and explain why.
I only have an idea. Can you help me plan it?
Yes. Send me a short description and I'll suggest the features, the right package and a clear scope before you order. Please message me first, it saves us both time.
Will I own the source code?
Yes. You get the full source code with clear comments and simple setup notes, so you or any other developer can continue the work.
Do you deploy the app for me?
Standard and Premium include deployment on Vercel or AWS. For Basic, I can deploy it as a gig extra or guide you through it.
Can you add features to, or fix, my existing app?
Yes. Send me the repo or a short description. I work with existing Next.js, React and Node.js projects. For small bug fixes, see my Bug Fix gig.
Do you offer support after delivery?
Premium includes 30 days of bug-fix support. For Basic and Standard, I can offer support or maintenance as a separate custom offer.
How do delivery and revisions work?
I share progress at key milestones so you can give feedback early. Revisions depend on your package. If the scope grows, I'll send a custom offer, no surprise charges.
