 244 | **Herndon Virginia**
 245 | **November 2000 – September 2006**
 246
 247 ..........................
 248 Lead Engineer(LMP Feature)
 249 ..........................
 250
 251 Led development LMP (RFC 4204) feature on the 15454DWDM multi-service transport platform.
 252
 253 - Wrote design document and test plans for the LMP feature.
 254
 255 - Implemented the IDL, CORBA layer, and TL1 (Transaction Language 1 – a widely used telecommunications management protocol) interface code for LMP feature
 256
 257 - Tracked incoming defect reports for the LMP implementation
 258
 259 - 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.
 260
 261 - Trained support engineers in the LMP feature during technology transfer
 262
 263 .................................
 264 Lead Engineer (15600 TL1 Feature)
 265 .................................
 266
 267 Led development for the TL1 interface for the 15600 multi-service transport platform.
 268
 269 - 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.
 270
 271 - 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.
 272
 273 - Worked closely with other Cisco sites in Texas, North Carolina, and California, as well as offshore developers in India, and Italy.
 274
 275 ________________________________________________
 276 Software Engineer(15327, 15454, 15600 platforms)
 277 ________________________________________________
 278
 279 Provided full life cycle support across a number of Cisco’s multi-service transport platforms
 280
 281 - 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.
 282
 283 - 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.
 284
 285 - 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.
 286
 287 - 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.
 288
 289 - 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.
