Summary

Since my first lines of code in 1983, my passion for technology has never waned and has taken me through various roles from developer to CTO at international corporations and agile startups. My technical foundation is in highly available cloud and microservice architectures. Since 2022, I have been focusing intensely on the practical application of generative AI. I believe our industry is on the brink of a major transformation. I want to help my clients seize the resulting opportunities with innovative yet pragmatic technology solutions.
