Custom
Software Development

We develop web platforms, customer portals and SaaS products when standard software does not fit your processes.

Our platforms handle applications with digital signatures, SEPA payments, member administration and delivery logistics. They run on AWS or Vercel, connect to ERP and invoicing systems, and we keep developing them long after the launch.

Our References
Your Processes

the software follows your workflow, not the other way around

Open Stack

TypeScript, Next.js and PostgreSQL, no license costs

Your Code

the source code and repository belong to you

Long-Term

maintenance and further development over years

What we build

Portals & Platforms

Customer portals, member areas and internal tools with roles, permissions and multi-tenant separation

Interfaces

Connection to ERP and inventory systems, invoicing (e.g. Easybill, DATEV export), Stripe and industry APIs

Automation

Background jobs, PDF generation, document processing and email workflows replace manual routine work

Hosting & Operations

Deployment with Docker on AWS or Vercel, with monitoring, error tracking and backups

Our tech stack

We build on the React ecosystem from web to mobile: one technology family for platforms, portals and apps. That keeps your project consistent, fast to extend and independent of single vendors, because these are open, widely used standards.

Next.js & React

Web platforms, SaaS products, customer portals and dashboards. Server-side rendering for speed and SEO, built to grow with your product.

React Native & Expo

Native iOS and Android apps from a single codebase, built in the same React ecosystem as the web. One team, one knowledge base, from browser to app store.

Node.js, NestJS & PostgreSQL

The backend for business logic, APIs and data, connected to ERP, payment and industry systems. Hosted on AWS or Vercel, packaged with Docker.

TypeScript end to end

One language from frontend to backend. Type safety catches whole classes of bugs before launch and keeps the code maintainable for years.

Project Example: Member Platform for Freie Wildbahn

The Task

Freie Wildbahn e.V. supports its members around the Künstlersozialkasse, the German social insurance fund for artists. Membership applications with signatures, payment details and consultation appointments needed to run digitally, for members and administrators alike.

The Solution

  • Step-by-step application flow with digital signature
  • SEPA and card payments via Stripe
  • Appointment booking for member consultations
  • Statistics dashboards for the administration, hosted on AWS
  • A collaboration spanning years: the platform is in its second generation

We also built the public KSK contribution calculator for the association. View the project reference

Frequently Asked Questions

When is custom software worth it?

When standard software forces you to bend your processes, when you maintain data in several disconnected tools, or when a product idea needs its own platform. In the initial consultation we tell you honestly if an existing tool would serve you better.

What does custom software development cost?

That depends on the scope: an internal tool with a handful of views costs much less than a multi-tenant platform with payment processing. After the initial consultation we estimate the effort and quote a fixed price per project phase.

Which technologies do you use?

TypeScript across the stack: Next.js and React in the frontend, Node.js and NestJS in the backend, PostgreSQL as the database. We deploy with Docker on AWS or Vercel. These are open, widely used technologies, so you are not tied to us.

Who owns the code?

You do. The source code and the repository are handed over to you, including documentation. Any developer familiar with the stack can take over.

What happens after the launch?

We keep operating and extending most of the systems we build. Several of our platforms have been developed continuously for years, with regular releases.
