Custom software
Web applications and portals that mirror how you work, instead of bending how you work to fit a standard product.
Software Development from Erfurt — Across Germany and Worldwide
RHINEC builds custom software for companies that need more than an off-the-shelf product. We work remote-first: our base in Thuringia is where we sit, but our projects run across Germany and beyond its borders. Whether you are in Hamburg, Munich or Zurich makes no difference to how we work together — an afternoon on site in Erfurt does.
We build web applications, interfaces and mobile apps from the first sketch to day-to-day operation. That includes the infrastructure: containers, Kubernetes, automated delivery, monitoring. You do not get a handover document and then silence, but a system somebody actually runs.
What we build for you
Interfaces and APIs
Connecting existing systems, breaking up data silos, making your ERP and your shop finally talk to each other.
Mobile applications
One codebase for iOS and Android, including delivery to both stores and the connection to your backend.
Cloud and operations
Kubernetes, automated delivery and monitoring, so nobody has to wonder who restarts the server after launch.
SaaS products
From the first idea through multi-tenancy and billing to a product your customers can sign up for themselves.
Modernisation
Replacing legacy systems step by step, without stopping the business — piece by piece rather than in one leap.
Erfurt, the surrounding region and everywhere else
Erfurt is closest to us, and for clients in the region a meeting on site is a matter of minutes rather than travel expenses. We regularly work with companies from Erfurt and the surrounding towns. For everyone else: video call, shared screen, shared repository — that carries a full project, and most of our clients are not based in Thuringia anyway.

How a project runs
First conversation
No strings attached. We listen and tell you honestly whether we are a good fit.
Concept and quote
In writing, with scope, timeframe and price — before anyone writes the first line of code.
Delivery in stages
Something you can look at on a regular basis, instead of one big reveal at the end.
Operation and care
Monitoring, updates and further development, for as long as you want us to.
Frequently asked questions
Do you work outside Thuringia?
Yes. The majority of our projects run entirely remotely — across Germany and internationally. Our base near Erfurt is where we sit, not the area we serve.
What does custom software development cost?
It depends on the scope. After the first conversation you receive a written quote with scope, timeframe and price, so that you have something to compare.
Which technologies do you use?
Angular and TypeScript on the frontend, Node.js and .NET on the backend, Docker and Kubernetes for operations, PostgreSQL and MongoDB for data.
Where is the data stored?
In Switzerland by default. If your project calls for a different location we settle that before the project starts, not in the small print.
Do you take over existing projects?
Yes. We take on maintenance and further development of code written by others, after a review that establishes what we are dealing with.
How long does a project take?
A well-scoped application is usually ready within a few weeks; larger projects run over months. We state the timeframe in the quote.
