Professional History

KAYAK, Concord, MA - Reverse Engineer

• 2/2004 - 10/2013.
• I started my career at KAYAK by building low-level components for Java web applications (configuration, logging, error handling, servlet lifecycle event listeners, and such). I also authored KAYAK's first build and deployment framework, which scaled by a factor of 30x before we had to rearchitect it.
• Built a distributed log processing system called "scrub". On a typical day, scrub performs log processing over 300-400 machines, and ingests 1.1TB of log data. Why not Hadoop? We needed a log processing system, Google had barely published their first paper on Map-Reduce, and Hadoop didn't exist yet. Scrub has worked well and it's still in active use today. (KAYAK uses Hadoop for data analytics, but not to produce core business metrics.)
• Architected KAYAK's data warehouse, and the surrounding ETL processes. This system loads ~ 40 million rows/day into 43 fact tables. As of last count, our data warehouse contained 18 billion rows and a couple terabytes of data. I've also learned a lot of database tuning tricks, to get efficient query execution on large tables.
• Built a piece of middleware called "Business Broker". Business Broker (aka "BB") is a Java web service that automates data exchange between Salesforce.com, Doubleclick, KAYAK's internal ad engine, and our data warehouse. This automation has significantly improved the efficiency of KAYAK's commercial team.
• Finally, I've done the usual set of things that you'd expect employee #9 at a startup company to do: firewall and VPN configuration, Linux administration, Drupal development, submitting bug fixes to open-source projects, babysitting httpd, bind, MySQL, and a variety of different mail delivery subsystems.
• Why is my title "Reverse Engineer"? It's a play on words: I like to tinker with things to figure out how they work, and I'm a fairly proficient debugger.

Intuit, Waltham, MA - Software Developer, Release Engineer

• 1/2000 - 2/2004.
• Designed, implemented, and tested low-level component libraries for use by business units across Intuit.
• Established a standard Apache build for use throughout Intuit, including source modifications to meet specialized business needs.
• Responsible for administration and configuration of 60+ Solaris machines in 6 deployment environments.
• Wrote a collection of tools for harvesting and analysis of application logfile data. (Gathering business data, operational performance, state-flow analysis). These tools were used to process 4-6 GB of log data per day.
• Served as a member of the development team for QuickBooks Site Solutions. Wrote APIs for domain registration and domain management. Managed domain name renewals for 75,000 web sites.
