Cooking
Tell you a secret, I'm a good cooker, specialized at Chinese cuisine. Only my friends know the taste of the dishes that I made. Maybe I'll open a restaurant in the future to invite more people to enjoy, who knows?

ABOUT ME
I Transform Data Into Value.
I led the data engineering team and architected the enterprise-level data center from scratch, which reduced the cost for data ingestion, data transformation, data integration and communication, accelerated the data query efficiency, and increased the data usage rate.
I applied expert strategies and machine learning algorithms to save the cost of more than $2 millions and contribute 10% of the profit. I addressed all kinds of issues and incidents, which indirectly saved the cost of more than $1 million.
