-..............................................
-Senior Software Engineer (Test Center Product)
-..............................................
-
-Designed, developed and maintained StackSafe's flagship Test Center product, which was awarded the 2008 ITIL Innovation of the Year.
-
-- Designed, implemented, maintained, and documented the product's TurboGears-based licensing system, including the design of its PostgreSQL database, and the sqlalchemy-migrations needed between releases.
-
-- Designed, implemented, and maintained the licensing and upgrade portions of the product's Rails-based GUI, including a Ruby-based cron job which would occasionally poll the upgrade server for new releases.
-
-- Designed, implemented, and maintained the product's Ruby-based command line interface.
-
-- Developed and maintained the products Python-based storage daemon, which was capable of surfacing a virtual machines QEMU disk image over the network by using qemu-nbd and nbd-client.
-
-- Helped develop and test the product's Python-based management daemon which was responsible for starting and stopping virtual machines.
-
-- Performed root cause analysis after build failures, sometimes having to dig pretty deep into code I was not written , including Python, C++, Ruby , and Perl code and bash scripts Many times these failures turned out to be locking/synchronization issues between various system components.
-
-- Maintained the Debian packages and apt-get repository using reprepro.
-
-- Implemented and maintained the installation scripts associated with the products deb-based packaging.
-
-- Customized the Debian install process to install our product along with the normal Ubuntu server installation, and to verify that the host machine supported virtualization. Since the Debian install process is not documented very well, this usually involved having to walk through the Debian-installer source to find out how it worked.
-
-- Designed, implemented and maintained the product's build environment, including a Python based nightly-build script which built all the source, loaded it onto the appropriate test machines, and run the smoke tests.
-
-- Acted as the primary QA engineer until a full time tester was hired, leading bi-weekly bug scrubs, and making sure all the outstanding issues were resolved before cutting a release.
-
-- Championed unit testing as an integral part of the normal development environment
-
-- Participated in code reviews, and monitored the SVN commit notices for questionable commits, especially after build failures.
-
-- Used Puppet to maintain the configuration Engineering lab's collection of build and test machines.
-
-- Submitted patches and bugs against the open source projects we were using on the product.
-
-- Worked closely with off-site engineers in California and New Jersey.

-| **Herndon Virginia**
-| **November 2000 – September 2006**
-
-..........................
-Lead Engineer(LMP Feature)
-..........................
-
-Led development LMP (RFC 4204) feature on the 15454DWDM multi-service transport platform.
-
-- Wrote design document and test plans for the LMP feature.
-
-- Implemented the IDL, CORBA layer, and TL1 (Transaction Language 1 – a widely used telecommunications management protocol) interface code for LMP feature
-
-- Tracked incoming defect reports for the LMP implementation
-
-- Participated in successful interoperability tests with the Calient PXC at the KDDI research labs outside Tokyo. Fixed and retested minor issues on-site during testing.. KDDI was very impressed with the quick turnaround time, saying it had taken a competitor months to make similar changes.
-
-- Trained support engineers in the LMP feature during technology transfer
-
-.................................
-Lead Engineer (15600 TL1 Feature)
-.................................
-
-Led development for the TL1 interface for the 15600 multi-service transport platform.
-
-- Assigned priorities for TL1-related bugs on the 15600 platform to a team of 7 engineers located in California, Texas, Italy, and India. Remove roadblocks associated with fixing the problems. Adjusted workloads to keep engineers from becoming swamped or burned out. Participated in most code reviews related to the 15600’s TL1 interface.
-
-- Removed 100K SLOC by aligning divergent code bases between the 15454 and 15600 platforms. The common code base freed up engineers who had previously been dedicated to either the 15454 or 15600. Fixing a bug or extending one platform also ended up being reflected on the other platform as well.
-
-- Worked closely with other Cisco sites in Texas, North Carolina, and California, as well as offshore developers in India, and Italy.
-
-________________________________________________
-Software Engineer(15327, 15454, 15600 platforms)
-________________________________________________
-
-Provided full life cycle support across a number of Cisco’s multi-service transport platforms
-
-- Wrote and maintained an extensive TL1 regression test suite in Expect. The test suite originally was meant to provide early testing for OSMINE deliverables. The tests were so successful, they began being used as a stability metric after branch syncs or merges. Before the tests were available, it might be weeks before a sync error was discovered. After the tests were implemented, sync errors were noticed within a day.
-
-- Implemented Telcordia’s COPY-RFILE feature. This was the first time the feature was developed by a vendor. Worked closely with Telcordia engineers to work out the kinks in their specification.
-
-- Resolved 800+ defects over 5 years, making me on of the top 5 contributors on the team. Wrote 700+ defect reports over 5 years despite not being a QA tester. Posted more defects than most of the dedicated testers.
-
-- Participated in multiple OSMINE certification cycles. The OSMINE testing cycle forced code delivery to Telcordia months before the software went through formal QA. This test suite guaranteed high quality software was delivered despite the lack of QA. OSMINE certification cost ~6M, so an unsuccessful certification effort would have been extremely expensive.
-
-- Had to carry a pager once or twice a year on a rotating basis in case any serious problems happened in the field that the regular support engineers couldn't resolve.
