About Me

Curious. Problem-solver. Empathetic.

I am a strong believer of the need of Data Science and Machine Learning in today's industries. Data Science is known to be a buzz terms, but undeniably will be part of our future. My interest mainly lie in the intersection between Data Science and Data Engineering, such as productionizing model code, creating data pipelines, and developing real-time analytics dashboard. I am currently pursuing a M.S. in Data Science degree at Columbia University to solidify my foundation in Machine Learning and improving my Engineering/Coding skills through projects and internships.

When I'm not solving data science problems, I love to create websites, webapps, and interactive data visualizations for organizations I believe in (and sometimes just for fun!).

I am currently looking for an internship for Fall 2019 and a full-time job starting January 2020, so contact me for any kind of work opportunity. If you just want to connect and talk about tech, send me a message too!
