• Developing a constellation of globally distributed, highly available indexing services that enable advanced access to (1) Meta's social graph database and (2) Meta's data warehouse.
• Rewriting the multi-pathed pipeline that tails and distributes millions of database writes with zero dataloss and bounded staleness to keep these indices consistent

• Built systems that track realtime events from millions of servers, process many billions of events per minute, perform aggregation and anomaly detection.
• Designed next-generation user experience for Facebook's mission-critical monitoring system

• Implemented a C++ API that records the total CPU and wall costs of processing each request received by News Feed's thrift server. Visualized and optimized an earliest-deadline-first scheduling algorithm used by News.
• Simplified allocation and deallocation of resources for News Feed's request context which contributed to 0.3% CPU gain and prevented potential memory leaks.
• Automated the collection of performance data from production machines which enables compiler optimization via increasing page size and pre-ordering hot functions.

Redmond, Washington, US

• Streamlined the report generation workflow in Microsoft Dynamics AX 7 by implementing a cloud-based report generator via the SysOperation framework which supports dialog input, reliable asynchronous execution and batch.
• Reduced customer's dependence on the obsolete report designer and as a result improved ease of use tremendously by simplifying a multi-step process while also making the user experience more logical.
• Navigated 3 new languages in X++, C#, and Typescript, new test frameworks, multiple architectures and multiple development environments.

Mountain View, CA, US

• Implemented schema support for one of Google's largest distributed data processing systems. Enhanced 3 internal debugging tools and introduced SQL-based filtering logic with improved flexibility and type safety.
• Contributed over 3000 lines of C++ to Google codebase. Released features for production use by over 100 Google employees. Refactored and improved test coverage for existing modules via extensive benchmarking, unit and.

Hanoi, VN

• Designed data loss prevention tool that identifies sensitive data at rest from bank servers. Integrated Perl-compatible regular expressions and Luhn algorithm to expedite detection and validation of unencrypted credit.
• Created text parser capable of extracting raw content and metadata from over 50 file extensions to accelerate PCREs-based pattern matching.

Singapore, SG

• Worked in a professional laboratory as part of A*STAR Outstanding Scholar Program.
• Collaborated with researchers on various experiments and lab procedures.
• Delivered a presentation on acoustic calibration system in a nationwide convention.
