About Markus Lindner

My Background

I’m Markus Lindner, a 27-year-old and dedicated IT freelancer based in Berlin. I am currently pursuing a B.Sc. in Engineering Embedded Systems at BHT Berlin with a strong focus on technical informatics and applied software engineering. I grew up bilingual in German and Polish, have excellent English skills, and work with international clients on a daily basis in different business contexts.

My Experience

From May 2019 to March 2024 I worked as a student employee at Siemens AG, where I gained valuable hands-on experience in IT infrastructure, cybersecurity, and software development. Since 2020 I have also been freelancing, building modern, user-friendly websites with WordPress, TypeScript, and React, offering personalized IT coaching, and handling sensitive cybersecurity incidents. In addition, I have set up IT infrastructures for lawyers and real estate agencies, implemented cloud systems, performed data recovery, and carried out reliable network installations for SMEs such as Bullet Shop Berlin.

My Approach

I start every project with a thorough assessment of your IT needs in order to identify risks and opportunities in detail, and then design scalable solutions such as secure networks, professional websites, and effective cybersecurity measures. I implement these solutions efficiently with a clear focus on reliability and long-term stability, while also offering continuous support, optimization, and personal consultation. The combination of my Siemens background and diverse freelance projects ensures that your IT systems are not only professional but also practical and well aligned with your business goals.

Why Choose Me

For every project I bring a practical, solution-oriented mindset. With industry-recognized certifications in cybersecurity, data privacy, and IT management, I deliver secure, reliable, and growth-driven IT solutions tailored to the needs of SMEs. I combine deep technical expertise with strong client orientation, ensuring that your business IT runs not only smoothly but also securely, sustainably, and efficiently over the long term.
