Hi, my name is Phattharanat Khunakornophat(Chuan).

"I have an avid interest in data science and data visualisation"

I have a year of experience as a Data Scientist and Machine Learning Engineer. Most of my tasks are about providing analyses to support a strategy team.

I gained experience in the field of spatiotemporal data and time series analysis whilst working on my senior project.

I am keen on learning to create good data visualisation. I admire John Burn-Murdoch and David Spiegelhalter for their works. I have a goal to create high-quality analysis and visualisation that are comprehensible for non-chart people. In my free time, I enjoy watching videos from the Royal Institution to expanding my knowledge and practising English.

Experience

Data Scientist/Machine Learning Engineer
