IT services and electronics repair from a single source.
ABC Systematik develops custom software, repairs electronics and computer systems and protects local networks – with solutions that run entirely on your own hardware.
Services
Three fields of business, one point of contact.
We are currently prioritising selected in-house developments. Project inquiries from new clients are welcome – delivery follows an individual review of availability and feasibility.
How we work
How an engagement works.
Fixed steps, no surprises – you know the cost and the outcome before work begins.
Inquiry
You describe your request – using the inquiry on this page or by e-mail.
Analysis
Review of the device or requirements, clarifying questions, feasibility.
Quote
Written quote with scope, price and timeline.
Delivery
Delivery, documentation and provision. Source code and rights are transferred once the project agreement has been paid in full.
Two rounds of revisions are included
Once the work is finished or close to hand-over, you look at the result and tell us what should be changed. Two such rounds are included in every engagement. Coordination during the work itself does not count towards them – that is part of the job anyway. As long as it stays within reason, it costs nothing. If it turns into a permanent state of affairs, we will tell you beforehand – not afterwards on the invoice.
Any further round of revisions is charged separately. We name the cost in the quote.
Shinsa
Developed and delivered by ABC Systematik
Shinsa
From idea to implementation, together.
Shinsa is for people who have an idea but not the technical know-how to build it – or who have already hit a wall with AI-generated code and need help. Two options lead to us:
New idea
You have a project idea but no development experience. For a fixed analysis fee we assess whether the idea is technically and economically viable. You get a clear yes or no – no empty promises.
Broken code – “vibe coding” rescue
Your AI-generated project no longer works, or you don’t know how to continue. We analyse the existing code and tell you honestly whether and how it can be saved.
What happens next
If the analysis is positive, you commission the implementation as a regular project. If there is no budget, Shinsa may in individual cases take on development in exchange for a stake in your project – whether and on which terms is decided by ABC Systematik after its own review. All details are agreed in writing before a project starts.

In developmentVom Handwerk ins Netz: Für einen Kfz-Fachbetrieb begleite ich die digitale Neueröffnung. Neben der technischen Umsetzung der Website stand vor allem das Ergebnis im Vordergrund: Mehr Anfragen für Werkstattleistungen über die organische Suche. Mit klarem Design, optimierten Ladezeiten und strategischem Local Marketing sorgt der neue Auftritt dafür, dass aus Suchenden in der Region verlässliche Stammkunden werden.

About
ABC Systematik
ABC Systematik is a registered business for software development, system analysis and IT services, repair of electronics and computer systems, and hardware trade. It is owned by Alexander Barwig, a certified software developer (Fachinformatiker Anwendungsentwicklung).
The common denominator of all three fields: technology that stays with the customer. Data is processed locally, devices are repaired instead of replaced, and source code belongs to the client.
