I’m working on Google’s logging infrastructure, a distributed large-scale system that allows for the collection, storage, and management of business-critical event records for all Google products, and aiming to make them cost effective and accessible for business insights, in a manner that respects user privacy and complies with policy.

Project experiences on

Logs auditing: Designed and built a large scale Flume pipeline, which ingests 1% logging data of all Google’s products (~5PiB) and scans them against Google’s privacy policies daily.

Logs Access: Designed and implemented read access control of logs, to satisfy read permission management of data with different levels of privacy and security requirements.

Logs Launch Privacy: Design and built logs launch workflow with logs privacy review, which ensures logging plan compliance with Google’s logging policies.

I did a fulltime internship in Tuniu, which is one of the largest online travel package provider in China. I was assigned in the app development group and was responsible for developing Dyfoo iOS app. It is an app for travel tickets booking and based on Facebook React Native framework. It has been downloaded over a hundred million times once it has been published.
