Custom-built instead of off-the-shelf

Where ready-made software, public AI services and the usual content management systems reach their limits, we build the right thing ourselves – with more than three decades of programming experience.

Since the 1990s

Custom software development

Bespoke applications for your processes

Not every business process can be sensibly mapped with standard software. Where industry solutions are too rigid, too expensive or too cumbersome, we develop an application that maps your process exactly – from requirements analysis through architecture and implementation to testing, commissioning, documentation and ongoing further development.

The range extends from desktop, web and database applications through interfaces (APIs) and process automation to the orderly replacement of legacy systems that have grown over time. The source code and the rights of use for the solution created for you belong to you.

Offline CMS

Maintain your blog and news securely

The usual content management systems put a login screen on the internet – and that is exactly where most attacks on websites begin. Our offline CMS runs locally on your computer instead. You write and design your posts offline; only the finished post travels to the server over a specially set up, tightly restricted route.

No CMS software, no login screen and no database is left behind on the web server. The website stays static – fast, frugal and without the constant pressure to update.

  • No user account on the internet
  • No database on the server
  • Write posts even without an internet connection
  • Your content stays with you
  • The method in detail in a personal conversation
Runs in-house

Fine-tuning of open-source LLMs

Your own language model with your data

Public AI services are convenient, but they have two catches: your data leaves the company, and the model knows neither your terminology nor your processes. Open language models such as Llama, Mistral, Qwen or Gemma can be run on your own hardware and retrained specifically for your use case – efficiently, via LoRA/QLoRA.

We check honestly beforehand whether the effort is worthwhile: often a clean connection to your existing documents is enough. If fine-tuning is the right way, the result runs on a single GPU workstation at your premises – with no running costs per request and no dependency on a provider.

  • Pre-sort support enquiries automatically
  • Texts in your terminology and house style
  • Structured data from invoices and forms
  • GDPR-compliant: no request leaves your network

Are you ready?

Since 2023, the computing and technology landscape has changed rapidly, in particular through the development of large language models (LLMs).

Frequently asked questions

What services does Computer Heiler offer?

Computer Heiler covers eight areas: remote support over an encrypted connection, on-site service in the Kaiserslautern area, data recovery from hard drives, SSDs, mobile devices and databases, maintenance contracts for businesses, AI consulting and prompt engineering, custom software development, a locally installed offline CMS for blogs and news sections, and the fine-tuning of open-source language models. The first five services are billed at an hourly rate, the three project services by individual agreement.

How does Computer Heiler bill?

Billing is to the minute. There is no minimum duration and no basic fee, so you only pay for work actually carried out. For project services such as software development, there is a non-binding initial consultation at the start, followed by a written estimate of the effort involved, before anything is commissioned. The full terms and hourly rates are listed on the services page.

How quickly will I get help?

As a rule within 24 hours. For problems that can be solved by remote support, a solution is often possible on the same day, because no travel is required. E-mail enquiries are usually answered within one working day. For urgent cases, a direct phone call is also possible.

In which area does Computer Heiler operate?

The on-site service covers a 50-kilometre radius around Kaiserslautern. This includes Neustadt an der Weinstraße, Pirmasens, Zweibrücken, Landau in der Pfalz, Rockenhausen, Kusel, Homburg in Saarland, Landstuhl, Ramstein-Miesenbach and Lauterecken, among others. Remote support is independent of this and available throughout Germany, wherever there is an internet connection.

Who is Computer Heiler suitable for?

For private individuals, freelancers and small to medium-sized businesses. Private customers usually come with slow computers, virus infections or lost data. Businesses additionally use maintenance contracts, custom software development and running their own AI models in-house. Having an in-house IT employee is not a requirement – on the contrary: many customers have an external partner for precisely that reason.
