Web App Development

When a website isn't enough

Your client needs a booking system, a client portal or an internal tool? I build web apps that do exactly what's needed. Nothing more, nothing less.

What to expect

Custom built

No compromises with off-the-shelf solutions. Your client project is developed exactly to the requirements.

Integration with existing systems

The app works with what's already there. Databases, external services, existing software.

Real-time features

Live updates, notifications, collaborative workflows. Users always see the current state.

Scalable

Architecture that grows with the project. Whether 10 or 10,000 users, the app stays fast.

Security

Login systems, CSRF protection, input validation, secure database access. Standard, not an add-on.

Hosting and operations

I set up hosting and make sure updates are deployed without downtime.

How your web app is built

1

Requirements

What should the app do? Who uses it? What needs to be connected? We sort that out together.

2

Technical planning

I design the architecture and show you a prototype before real development starts.

3

Development

Step by step, with regular updates and room for feedback. No big bang at the end.

4

Launch and operations

After thorough testing the app goes live. I stay available if anything comes up post-launch.

Frequently asked questions

As soon as users need to log in, enter data or manage things. Booking systems, dashboards, client portals, internal tools. Anything where data needs to be stored or processed.

Mainly Next.js, React and TypeScript on the frontend, Node.js on the backend, PostgreSQL for the database. What makes most sense depends on the project, I explain that in the conversation.

We decide that upfront. I can set up and run hosting, or hand it over completely to you or your client. Both options are on the table.

Authentication, CSRF protection, input validation, secure database access. That's standard for me, not an add-on. Documentation available on request.

Yes, if that's what you want. I develop, you're the contact for your client. White-label development is the norm here, not the exception.
