My love for technology began early. As a child, I was fascinated by how things worked. By the age of four, I had taught myself DOS commands before I could even read. I used to watch my father using his PC and, once he was at work, I began experimenting on my own using trial and error. That’s how I gradually learned how to launch programs and games. At 11, I wrote my first programs and developed both text-based and graphic games in C and Delphi. By the age of 14, I had created my first website featuring an interactive assistant – naturally within the technical limits of the time and far from what we now call artificial intelligence.

My professional journey has taken me through various industries and areas of specialization:

• Since 2009: IT support (1st & 2nd level) and CISCO system installation and maintenance for a Europe-wide pet supply distributor
• Since 2010: Application development & server administrator for an international media service provider
  – Here I automated the majority of server-side tasks
• Since 2011: Entered the field of industrial robotics – from installation and programming to customer handover for an international industrial service provider
  – I developed a cavity protection dosing system achieving 0 mg underspray and a maximum of 0.2 mg overspray
• Since 2012: Team lead for robotics & PLC programming, specializing in cycle time optimization & process control
• 2014: Expert in simulation & robotics, trainer for new employees, process optimization in multiple areas
• 2016: Project lead engineer for simulation & robotics
  – Additionally, I handled on-site part design using CATIA V5 during construction phases at client locations
• 2018: Founded Sitter Technical Solutions – initially focused on robot simulation & programming, later expanded into web design, online marketing, and digital media due to the COVID-19 pandemic
• Today, I combine my technical expertise with digital innovation to provide custom solutions for businesses of all sizes.
