• 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 Feed's services to aggregate and rank user stories.• 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 processing.• 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 load tests.

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 card data.• 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.
