Custom development
From a client portal to a full SaaS product, I plan, design, build and ship web apps end to end. You work directly with the person writing the code, see progress every week, and get an app built on proven tools that any good developer can maintain.
Custom web application development by Harsh Prajapati, freelance web developer in Ahmedabad, Gujarat, India, working with clients across India and worldwide.

FAQs
Web apps vary a lot in size, so I quote after a short call. You get a fixed written quote for a clear first version, and later features are quoted separately, so costs never creep up quietly.
A focused first version usually takes 4 to 12 weeks. I deliver in weekly steps with a demo link, so you can use and test the app long before launch.
Usually Next.js and React with TypeScript, Node.js, and PostgreSQL or Supabase. These are mainstream, well-supported tools, so you are never locked in to me.
Yes. I help you decide what goes into the first version, map the main user flows and remove what can wait, so you launch sooner and spend less.
You do. The code, database, designs and accounts are yours, and at handover you get everything with documentation.
