Custom Development & Integrations

Full-Stack & Web Development

We develop web applications and backend services with a modern stack, clean architecture and complete documentation, from database to API to user interface. So you don't depend on a single vendor.

Web development at a glance

A good web application is more than a pretty frontend. It needs a well-thought-out data model, a robust API, meaningful tests and an automated path into production. We deliver the complete stack from one team — avoiding the typical friction between frontend, backend and DevOps disciplines.

In the frontend we rely on TypeScript with React, Next.js or Astro and Tailwind; in the backend on Node.js/NestJS, .NET or Python (FastAPI), with PostgreSQL, MS SQL or MongoDB as the data layer. Operation runs in the cloud (Azure, AWS, Hetzner) with CI/CD via GitHub Actions. These technologies are deliberately established and well documented — so other developers can maintain your application later too.

Whether a new application, replacement of a legacy system or extension of an existing platform: we work iteratively, with regular reviews and traceable architecture decisions. You receive working increments instead of a black-box mega-project.

Use cases

Web development in practice

// 01

Replacing a legacy system

A grown Access or Excel solution is replaced by a web application several sites can use at the same time.

// 02

Customer portal

Customers see their orders, deliveries and documents themselves instead of asking service.

// 03

Backend for an app

API and data layer for a mobile application, including permissions and operation.

How we proceed

Web development: step by step

1

Clarify the requirements and the user groups

2

3

Build, test and ship in iterations

4

Set up operation and monitoring, then hand over

FAQ

Web development: frequently asked questions

Still have open questions? We're happy to clarify them in an initial call.

Which technologies do you work with?
At the core TypeScript, React/Next.js/Astro in the frontend and NestJS, .NET or FastAPI in the backend, plus PostgreSQL and cloud operation with CI/CD. We choose the stack to fit your requirements, not fashion.
Can you replace an existing legacy system?
Yes. We analyse the legacy system, plan a step-by-step replacement with data migration and keep operations stable during the transition — instead of switching with a risky big bang.
Do you also run the application afterwards?
If you want, yes, including updates, backups and monitoring. You can equally hand operation to your own IT or a third party. We set up deployment and documentation so that both stay possible.
