Worked on a critical internal security project from scratch to protect customer and corporate data inside AmazonInnovated an out-of-process daemon solution to reuse the existing Java code to minimize the development time from months to weeks to support C++, Ruby, and Perl languagesLed the team from 10+ beta customers in Java to 400+ production customers (over 15% production hosts) in 4 languages over 4 months Fixed scalability issues to unblock amazon.com website rollouts, using only 80 hosts of EC2 M1 Extra Large Instance to support North America region as a resultImproved scalability of the internal security service to meet the demands of auto-scaling of the amazon.com websiteImplemented and deployed an emergent fix in 8 hours to stop publishing security policy updates to all tier-1 Identity service on Thanksgiving day in 2012, right before the year-end traffic peak

Worked with in-house distributed memory object caching team to support latency based routing, retry, and jittering to better tolerate transient network issues, cutting false alarms in halfOverhauled availability and latency alert monitoring on the critical path to automatically pin point the problematic machines that have impacted overall performance while minimizing noises Simplified alert enabling and disabling process from days to 5-minutes, winning a Gold Star Award for top performers at MicrosoftInnovated a pod-level alert that identifies problematic pods causing sporadic latency spikes and helped dramatically smooth out 99.9 percentile latency

Co-designed a lock-free mechanism to keep track of profiler code remaining on the stack, which is 17% faster than the interlocked approachAssisted to deliver attach and detach profiling APIs to allow profilers to be loaded and unloaded dynamically in a running managed application Developed GC attach, in-proc SxS pick-one, and multiple runtime features for v4 CLRProfilerHandled customer facing activities including resolving the system-level issues such as tracking the nested exception being rethrown from native code and dealing with the implementation changes during stack walkingWorked with Windows team to implement an out-of-process error reporting mechanism for v4 CLR applications running on Windows 7 (more robust, and safer error reporting solution than the previous in-process model)Invented an in-proc SxS error reporting solution for v4 CLR running on preWin7 OSes, resulting in a US patent number 8,429,454Investigated and fixed various managed error reporting, mini-dump and IL stepping issues for both internal and external customers
