EXPERIENCE
SENIOR RUBY ON RAILS MANAGEMENT CONSULTANT San Francisco, CA 2015-Present
 Hired by Vice President of Engineering at well-known AdTech startup to diagnose and fix
dysfunctional Ruby on Rails development project. Redefined responsibilities of each team member;
appraised off-shore development team and identified alternative human resources; implemented code
review process, test-first TDD, automated code quality standards, instituted new issue tracker, and
delegated migration to Continuous Deployment (CD); inspired team around common goal of
“Textbook Development.”
 Hired by boutique EdTech content management system (CMS) to provide architectural insight into
junior Ruby on Rails and Backbone/Marionette Javascript development team. Identified and reported
on root issues including: problem employees, feasibility of corporate deadlines, migration to cloud
platform Amazon Web Services (AWS), conversion of monolithic codebase into microservices
Service Oriented Architecture (SOA), technical debt of legacy ColdFusion codebase and strategies to
accelerate its porting into Ruby on Rails, flattening of unscalable multi-tenant design into monotenant VMware stack, and cutting costs by simplifying and prioritizing objectives using Six Sigma.
SENIOR RUBY ON RAILS TEAM LEADER, COMCAST Philadelphia, PA 2014-2015
 Founded & managed the X1 Special Ops team to rapidly prototype new software to solve highprofile, high-visibility projects; led team of 4 developers and 1 project manager
 Conceived solution to $100MM+ problem in Comcast’s X1 division; successfully designed,
prototyped, pitched to vice presidents, and received funding to launch “XIST” project
 Architected, coded, and led team to develop XIST software, a massively distributed, concurrent,
multithreaded enterprise JSON API; XIST can identify if a Comcast cable box is experiencing a
known issue (i.e., a “bug”); built using Ruby on Rails and vanilla Ruby, Oracle 12c, MemSQL,
Percona SQL, OpenStack, Splunk, Capistrano, and a custom Ruby concurrency engine; API is
capable of 120 requests per second, for integration into all X1 Tier 1 support tools, including
Einstein call center software and Tech Nucleus iOS in-home technician app; XIST eliminates
dispatching technicians and replacing hardware caused by known issues, which executives estimate
to be half of Tier 1 support cost for X1

Architected and coded “Big Blue,” an enterprise Rails app capable of restarting all 30+ million
Comcast cable boxes in less than 1 hour; Big Blue was used in dozens of disaster recovery scenarios

multithreaded Ruby, Rails, Redis, Resque, and Splunk code running on 150 worker servers
Architected, coded, and led team to develop “Truck Roll Workbench” app, which illuminated
$100MM+ ITG (Interactive Troubleshooting Guide) problems in Comcast call centers; successfully
met emergency request from Comcast VP to build the app with my team in 4 days using Ruby, Rails,
Resque, and Bootstrap
Concieved, architected, and led development of OmniDevice, an Oracle-to-Pentaho-to-distributedRedis, map-reduced, sub-millisecond database to find any Comcast device, keyed by over two dozen
device identifiers. Rapid adoption of the OmniDevice API will save Comcast decades of man-hours.
