Software Engineer @ From August 2013 to Present (2 years 5 months) San Francisco Bay AreaPerformance Engineer @ Performance analysis, optimization, modeling, simulation, JVM tuning, benchmarking, workload generation, stress testing, database performance. From June 2012 to August 2013 (1 year 3 months) San Francisco Bay AreaSoftware Engineer @ I was working with the Network Management Systems group under Amazon Web Services (AWS). I resolved stability issues with a legacy implementation of TACACS (an authentication protocol) being used in production. I also extended it with new features that improve logging, handling passwords in a more secure fashion, as well as adding capabilities to transmit information via UDP. I refactored and cleaned up legacy Perl code that manages TACACS deployments and related services. I prepared documentation that describes step-by-step how to extend and deploy TACACS and accompanying packages to new AWS data centers as they come online. I laid the foundations for a backend to an internal web service that will be used by network and systems administrators to query statuses and information about devices in the network (such as switches and routers). From April 2011 to April 2012 (1 year 1 month) Greater Seattle AreaSoftware Engineering Intern @ I worked on the Google Chrome web browser. I deployed A/B experiments to the Chromium dev. channel where the goal was to compare different network-stack parameters in reference to the status quo and set them to more optimal values if possible. This involved setting-up experiments, collecting, reasoning and analyzing data, observing trends, refining experiment ranges, and forming hypotheses based on these observations. I implemented miscellaneous bug fixes and feature additions, including extensions the V8 JavaScript engine. From May 2010 to September 2010 (5 months) DB2 Kernel Development Intern @ I was involved with the index manager and performance dev. teams under the DB2 DBMS kernel group. Optimized handling of query operations for the DB2 index manager. Implemented and extended performance monitoring infrastructure for the DB2 index manager. Involved in porting and extending an internal DB2 benchmarking utility. From May 2009 to May 2010 (1 year 1 month) Toronto, Canada AreaSoftware Developer @ I wrote a (Windows) DLL that was used as a component of a larger program to uniquely identify a host machine (for detection of copyright violations). From April 2007 to June 2007 (3 months) Intern @ Project involved modeling and analysis of wind data, and applying the results to compute and predict wind power. This would improve the ability to predict energy generated via wind turbines. From January 2006 to March 2006 (3 months) Master of Science (MS), Computer Science @ University of Toronto From 2007 to 2010 B.S., Computer Engineering @ University of Sharjah From 2001 to 2006 Ziad Hatahet is skilled in: Distributed Systems, Python, Parallel Programming, Java, Object Oriented Design, Software Engineering, Computer Science, C++, Eclipse, C, Databases, Linux, Software Design, Algorithms, Machine Learning, Git, Scalability, Web Services
