Hi there! I'm
Koh Wyhow
Data Scientist and Web Developer.
Data & analytics, automating boring work, machine learning, data visualization, web development.
Currently at Roche Services & Solutions (RSS) Asia Pacific.
I enjoy solving problems using technology, focusing on data and analytics, cloud computing, and web development. I also like to work on projects which have positive impacts on society:)
Trained as a mathematician, I've been passionate about technology since self-studying Microsoft Excel and R back in 2015.
My background as a former Further Mathematics lecturer helped me build my communication skills, for me to explain my work in non-technical terms, while guiding developers in technical matters. I currently focus on building using Python, SQL, and JavaScript.
