Web app development

When you need an app, not just a site

If you answer the same enquiries by hand every day, send the same documents over and over or wait for someone to change a price on your site, the site can take that work over. Anything that repeats can move into an admin panel, a calendar or an automatic email.

What it can do

• Bookings and calendars for appointments or departures
• An admin panel in Serbian or English for prices, offers and dates
• User accounts and sign-in
• A database
• PDF documents and email notifications
• Training on how to use it, so you don’t need a developer for every change

Example: the Na Izlet agency

The old WordPress site of the Na Izlet agency was slow on phones and hard to keep up to date with new departures. The new site has an admin panel where the agency adds trips, dates and prices on its own, a departure calendar, trip sign-ups and a booking system with a bus seat map.

What we like most is that we add new departures and prices ourselves and don’t wait on anyone. And the site finally opens properly on a phone.

Technologies

I build apps with Next.js, React and TypeScript, with the database and user sign-in handled by Supabase. For you that means a site that’s fast on phones, secure sign-in and easy to extend with new features later.

Price and timeline

A web application costs €1,200 to €2,500, and the timeline is 4 to 8 weeks, depending on the features. If you only need a site you can edit yourself, without bookings and user accounts, that’s €500 to €1,000.
