My masters degree was in chemical engineering. My computing skills were started with Computational Fluid Dynamics for a commercial company. These codes often have tens of millions of lines of code and are challenged by computational resources such that numerical methods of various kinds are used. I then moved into a job at Diamond Light Source as a scientific software engineer and a data acquisition expert. I worked with scientists to collect data using robotics and analyse data using various algorithms. After this I worked on machine learning for an oil company. The task was to validate the computational science and deploy it to the cloud software as a service or SaaS.
