Hello, my name is Nicholas Leong.
I am a data scientist, currently working in an online classifieds tech company. In my years of experience, I have fully designed batch and streaming pipelines, improved data warehousing solutions and performed machine learning projects for the organization.

During my free time, I like to work on my own projects to improve my skills. I also write about my work, projects and experiences to share them with the world. It's been a great journey so far.

My goal is to provide value to society.
Data is my pathway towards that goal.
