Measurement • diagnostics • repair

When something stops working, I find the cause.

From heavy equipment electronics and industrial controllers to IT networks: engineering-based diagnostics, clear communication and documented results.

How can I help?

One coordinated solution for complex faults.

From on-site assessment through workshop repair to commissioning, the same person follows the job from start to finish.

Heavy equipment electronics and diagnostics

Targeted testing of controllers, instrument clusters, sensors, wiring harnesses and CAN bus faults.

  • JCB, John Deere, CAT and other machinery
  • PCB and controller repair
  • Communication and power-supply faults
µA

Electronic repair

Repair of industrial and custom electronics when complete unit replacement is expensive or no longer available.

  • Component-level troubleshooting
  • Firmware and memory backup
  • Soldering, component replacement and final testing
LAN

IT networks and system support

Reliable wired and wireless networks and day-to-day IT support for businesses.

  • Structured cabling and Wi-Fi
  • Point-to-point wireless links
  • Troubleshooting and documentation
SEC

CCTV, alarms and automation

Installation, repair and maintenance of security systems, with gate automation integration.

  • IP and analogue CCTV systems
  • Alarm and access-control systems
  • Reworking and stabilising existing systems

Transparent workflow

Measurement instead of guesswork.

I clearly distinguish what is proven, what is still a hypothesis, and which next test will narrow the fault down.

01

Symptoms

I collect the symptoms, history and available documentation.

02

Measurement

Targeted testing of power, signals, communication and loads.

03

Repair

A cost-effective, verifiable intervention based on the identified cause.

04

Final verification

Functional test, re-measurement and a clear summary of the completed work.

Repair log

Real faults. Traceable engineering reasoning.

These cases are more than references: they show the types of technical problems I can solve effectively.

Behind the name

Engineering thinking, direct communication.

As an electrical engineer and computer engineer, I approach a heavy-equipment controller, a failed PCB or a company network in the same way: understand it first, then repair it.

I also like restoring systems that have become difficult to understand over the years. The goal is not a flashy workaround, but a stable solution that remains traceable and serviceable later.

What is the symptom?

Briefly describe what is not working, what machine or system is involved, and what happened before the fault appeared. A photo, model number or fault code can greatly help the first assessment.
