Work include:- Improve the efficiency of Integer Linear Program Solver.- Enhance data piping and improve infrastructure's complexity while resolving tech debt.- Implement algorithms, models and do data analysis during verification.In the past, I worked under Geo (Google Maps) for 3 years as a fullstack engineer. Projects includes building a centralized metadata system and integrate it with the current workflow for the Google engineers. I've also worked on an internal application that's based on NLP, which uses substitution to generate different strings and sentences.

Modify the original Java Zookeeper components and enhance internal monitoring and watchdogs. Work as a Zookeeper DRI and solve live site issues.2. Design and complete the cross-environment feature for the new service AutoZK.3. Work on internal machine moves to re-organize our host machine's configurations.By the end of the year 2017, our ZKaaS service's SLA improved from 99.9% to 99.95% and occasionally hits 99.99%.AutoJava1. Fix bugs and provide alternative versions. Enhance monitoring, add watchdog service and solve live site issues. Updated several Java packages regularly and solved issues related to package release.2. Add new application that uses Java and C++ to show application's internal use of JVM via MBeans. Expanded the internal library via JNI calls.3. Customer support.From the end of 03/2017 to end of 04/2017, the number of environments using the service increased from 67 to 83, showing good customer satisfaction. The project's scope expanded from 1 application to 3 with better monitoring and new watchdog system.AutoIIS1. Adopt the service AutoIIS by solving live site issues and bug fixing in C# and Shellscript. Updated the old codebase for OS image compatibility. 2. Partner with another teammate to re-design and deliver this shared service in our new engineering system. We also answered internal customer questions.Results: Live site issues significantly reduced from about 1/week to 0-1/month. We ensured safe rollout the application after all the new changes.
