Work Experience

May ~
August 2009
Yahoo! Inc.

Tools Developer Intern - Burbank, CA

  • Developed priority 1 features for a test manager web application in JSP, javascript
  • Learned how a controller based performance testing system (yPerf!) worked (written in Perl)
    • Did a couple of bug fixes to support load testing of an advertising server
    • Created a plugin to the system to gather statistics through a script and format results back to the controller
  • Wrote several unit tests for three modules of the yPerf! which caught relevant bugs.
  • Gained strong background in Linux

May 2005
Azeus Systems Philippines, Inc.

Summer Intern - Manila, Philippines

  • Performed code inspection on a module of an Electronic Licensing System
  • Wrote comprehensive Java documentation and created JUnit tests for the assigned module

Academic Projects

Spring 2009
Peer-to-Peer File Sharing Application

C++, POSIX Pthreads

  • Developed p2p server and client object that allows user searching, downloading, and uploading on established network. Pair project
  • Implemented bit-vector for optimized keyword searching

Spring 2009
Folksonomy Visualization with Relation Extraction on South Africa Flickr Tags

Java, Opennlp, Stanford parser

  • A pair project where we used flickr tag data to generate folksonomy tree and label links with relationships between two entities
  • I worked on the relation extraction module. Relationships are extracted from web page results using Google Search API. Potentially relevant sentences are parsed using stanford parser to generate a dependency tree. Heuristics are then used to extract the relationship (noun and verbal).

Spring 2009
Client and Multi-Threaded Server Communication

C++, UNIX TCP Sockets, POSIX Pthreads, OpenSSL MD5

  • Developed client that sends 3 types of requests: get file, get filesize, and resolve ip address
  • Implemented server that handles client requests, with strict error checking and graceful shutdown

Fall 2008
USC Campus Spatial Database Application

Java Swing, Oracle 10g, Spatial Database Java API

  • Created a graphical interface which lets users draw polygons on the campus map and the system marks the locations of tram stops and students (stored in a database) within the drawn area

Fall 2008
A* and Theta* search on a Maze

C++, STL heap algorithms

  • Implemented A* and Theta* search algorithm on a text file maze
  • Analyzed the limitations of both algorithms and came up with examples to demonstrate sub-optimality
