 148
 149 - Helped develop and test the product's Python-based management daemon which was responsible for starting and stopping virtual machines.
 150
 151 - 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.
 152

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.
 158
 159 - 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.
 160
 161 - 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.

 176 Cisco Systems
 177 -------------
 178 | **Herndon Virginia**
 179 | **November 2000 – September 2006**
 180
 181 ..........................
 182 Lead Engineer(LMP Feature)
 183 ..........................
 184
 185 Led development LMP (RFC 4204) feature on the 15454DWDM multi-service transport platform.
 186
 187 - Wrote design document and test plans for the LMP feature.
 188
 189 - Implemented the IDL, CORBA layer, and TL1 (Transaction Language 1 – a widely used telecommunications management protocol) interface code for LMP feature
 190
 191 - Tracked incoming defect reports for the LMP implementation
 192
 193 - 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.
 194
 195 - Trained support engineers in the LMP feature during technology transfer
 196
 197 .................................
 198 Lead Engineer (15600 TL1 Feature)
 199 .................................
 200
 201 Led development for the TL1 interface for the 15600 multi-service transport platform.
 202
 203 - 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.
 204
 205 - 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.
 206
 207 - Worked closely with other Cisco sites in Texas, North Carolina, and California, as well as offshore developers in India, and Italy.
 208
 209 ________________________________________________
 210 Software Engineer(15327, 15454, 15600 platforms)
 211 ________________________________________________
 212
 213 Provided full life cycle support across a number of Cisco’s multi-service transport platforms
 214
 215 - 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.
 216
 217 - 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.
 218
 219 - 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.
 220
 221 - 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.
 222
 223 - 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.
