I have a diverse and extensive background in software engineering, with experience in full-stack development, backend engineering, system administration, and DevOps. I started building websites as a full-stack developer while studying software engineering at university. Upon graduating, I transitioned to a full-time role as a Backend Engineer where I developed and maintained robust server-side applications. Later, I expanded my skillset by taking on the challenging position of System Administrator due to my proficiency in Linux operating systems. In this role, I ensured the optimal performance and security of our infrastructure. Over the years, my career has evolved as I adopted modern DevOps practices, allowing me to develop, test, and deliver software more efficiently and effectively. I am continuously seeking new challenges and opportunities to learn and grow. As a developer, I'm not just writing code, I'm building tools that directly improve the stability, usability, performance, and security of our software and services.
Hello! I've used a lot of different technologies for work (Python/Django, PHP/Wordpress, git, SQL, AWS, HTML/CSS/Javascript) and constantly seek new programming experiences on my own, so I'm prepared to help with a wide variety of languages and topics. Code is a tool for communicating not just with computers, but with humans too - I care a lot about testing code and making it understandable.

I'm currently a full-time startup managing director with main focus in technology, where provide two solutions: 1) driving behavior evaluation based commercial fleet management 2) rolling stock based digitalized railway infrastructure inspection based on our dual edge-AI camera and enterprise cloud platform. I spend most of my time on managing developers or developing myself for the industrial design, AI engine, computer vision application, hardware (10 layer PCB with 3 subsystems), imaging system and camera, cloud application and a custom Linux kernel where I develop some of the basic kernel drivers as well business development and some communications. Last year I had 5 masters thesis students in - AI, embedded systems and cloud - where I was their industrial advisor and indeed that was great fun for me.
