Define IP pool strategies to protect email reputation for different types of emails. Lead the development of single-page web application for administrators to monitor and take action on abusive email usages on our platform.

Working with a team of talented, passionate, fun engineers and designers to build the next generation of email experiences. Mailbox apps are running on millions of iOS devices and Android devices. The efficient and intelligent cloud servers for email syncing are developed in node.js, MongoDB, RabbitMQ and are deployed in AWS.

Using Node.js, I have built a load testing framework that helped identify performance bottlenecks in the multi-tiered servers before Mailbox was launched. I also enhance the error reporting and handling system for Mailbox to better recover runtime errors. After researching email threads from various email providers, I have co-invented and developed a patented solution to extract relevant conversation from an email thread. I also implement cloud search to let user quickly narrow down for the emails that they are interested in.

I led the development of an Android solution for HP's ePrintCenter to allow user to print documents from any cloud connected printers. The Android application authenticated user through OAuth 2.0 into HP’s cloud-based, RESTful web services that allowed user to upload/browse/select/print documents from HP printer that was discovered based on user’s location or preference.
