About Me

Who Am I?

My background is in Electronics Engineering and I have worked as a Software Engineer and Data Scientist in various contexts.
I have experience using statistical modelling and machine learning to extract valuable insights and build useful products from data.
As much as I revel in autonomy, collaborating in a multi-disciplinary team is where I am most useful.
In both personal and professional projects I tend to zoom in on the details and work meticulously.
What I love about science and technology is that there is a near endless amount to learn, which makes it easy to stay curious and see everything as a learning opportunity.
