Custom web application development

A web application is software your users or your team use in the browser with nothing to install: a booking platform, a data dashboard, an internal tool, a client portal or a SaaS product. We build them from the first sketch to launch.

Every application is built and supervised by one senior engineer with more than ten years on React and TypeScript systems, from large companies and institutions to startups. AI tools speed up the build, so you get a finished product faster.

If it can be imagined, it can be built. There is no requirement that cannot be solved, and for the more complex things we look for the best way together.

What you get

Analysis and scope
Together we decide what the application must do on day one and what can wait, so the budget goes where it creates value.
Interface design
Clear, fast and mobile-friendly. If you already have a design, we build to it.
Frontend and backend
The whole system in one place: interface, server side, database and user sign-in.
Integrations
Payments (Stripe), banks (Plaid), CRM, email, WhatsApp and the other services you already use.
AI features
Chatbots, text analysis, voice input and content generation, built in where they genuinely help.
Launch and maintenance
Cloud setup (AWS, Azure or simpler hosting), error monitoring and backups, and support after launch.

Who it is for

  • Companies running their work on spreadsheets and email that need one system for data, tasks and reports.
  • Startups that need a first version of the product (MVP), fast and on technology that can grow.
  • Service businesses that need online booking, payments or a customer portal.
  • Teams with an outdated application they want to modernise without stopping work.

How we work

A clear process with short cycles and continuous visibility. One person leads the project from the first call to launch, and AI speeds up development under the review of an experienced engineer.

  1. Discovery

    We define goals, scope and priorities. Before work begins, you get a timeline and a price range.

  2. Prototype

    We build a clickable prototype to confirm the direction early, while changes are still easy.

  3. Development

    We develop in short cycles, with regular releases you can test and review.

  4. Delivery

    We launch, hand over the code and documentation, and continue with maintenance and upgrades.

Technologies we use

Frontend
React, Vue, Angular, TypeScript, Next.js, Vite, Tailwind CSS
Backend
Node.js, NestJS, Python (Django, FastAPI), PHP (Laravel), Java and Spring Boot
Data and cloud
PostgreSQL, Supabase, AWS, Azure, Docker
Testing
Jest, React Testing Library, Cypress
Flexibility
The technology is chosen to fit the project, not the other way round: Python, PHP, Vue, Angular and more, or whatever you already use.

How much does a web application cost?

What drives the cost of building a web application: scope, integrations, design, security and maintenance. How to get an accurate quote and where to save safely.

Questions about web applications

How much does a web application cost?

Prices start from €1,800, and the hourly rate from €35 per hour. The final amount depends on complexity: the number of screens and features, integrations, design and security. After a short conversation you get a free scope estimate and a price range, with no obligation. Prices are indicative and exclude VAT.

What is the difference between a website and a web application?

A website mostly shows content: a company, its services, a blog. A web application lets users do something: sign in, enter data, pay, book or manage an account.

Can I add new features later?

Yes. We build modularly and with tests, so new features can be added with less risk of breaking what already works.

How long does it take to build a web application?

A simpler application can be ready within a few weeks, while more complex systems take up to a few months, depending on complexity. I work in short cycles, so you can test parts of the application long before the end of the project.

Who owns the code?

You do. After delivery you get the source code, access and documentation, so you can keep developing the application with us or with anyone else.

Does a web application work on phones?

Yes. Every web application we build is mobile friendly, and if needed it can be a PWA that installs to the home screen. If you need an app in the App Store and Google Play, see mobile app development.
