ABOUT ME
resume
I have been working as a freelance database expert for over 30 years.
My specialism lies in Microsoft SQL Server across all versions –
from design and development through to administration
and performance optimisation and migration.
During this time, I have supported companies across a wide range of sectors
and sizes: from medium-sized manufacturing firms
to international corporations such as Bosch and Telefónica, right through to
public sector organisations.
What drives me: making complex data problems tangible
and delivering solutions that work in the long term.
Outside of work, I am active in CrossFit and competitive shooting –
there, too, I value accuracy and precision.
