Over 30 years of technical experience
Technology has been a constant thread throughout my life. Over the past 30 years, I have worked as an installer, service technician, and product specialist across a wide range of technical disciplines. In doing so, I have gained experience with electrical, precision mechanical, and pneumatic systems, ranging from industrial equipment and marking systems to medical displays and payment terminals.
Given my passion for technology and years of hands-on experience, the move to self-employment was a natural choice. Markus Techniek was founded in December 2014: a company where craftsmanship, quality, and personalized service are our top priorities.
Today, I assist both residential and commercial clients with electrical installations, renewable energy systems, troubleshooting, service, and maintenance. In doing so, I always prioritize one principle above all else: delivering a solution that both the client and I fully support.
One point of contact, a strong network
In addition to my own expertise, I work with a network of trusted professionals and specialized suppliers. This allows me to respond flexibly to a wide range of projects, while you benefit from a single point of contact throughout the entire process.
