Summary
Since my first lines of code in 1983, my passion for technology has never waned and has taken me through diverse roles from developer to CTO at international corporations and agile startups. My technical foundation lies in highly available cloud and microservice architectures.
Since 2022, I have been dedicating myself intensively to the practical application of generative AI. I am convinced that our industry is on the brink of a monumental shift. I want to help my clients effectively leverage the resulting opportunities through innovative yet pragmatic technology solutions.
