Personal information
I'm a customer-success driven IT-specialist in the fields of PostgreSQL, data engineering and application architecture. The last years I conducted several RDBMS design and data-presentation projects, alongside creating business opportunities in the field of IoT data-gathering, face regocnition, HR-facilities and computer directed natural dialogues. My software has applications in HR-businesses, several art projects, psychometric tests and large scale seismo-damage projects.
Most of this happened after concluding twenty years of running the IT and recruitment department of a mid-sized Unix consultancy company.
After years of combining database and software development with being part of the board of a company with 140 employees, I am foremost dedicated to use Data Science as a means to improve businesses. I'm exploring R and Go next to PostgreSQL as my tooling.
Last, but not least, circularity and sustainability grabbed my interest while being involved in some startups.
