Hired, trained, and led a team of eight senior, mid-level, and co-op software engineers:▪ Created a clinical (GCP) data analysis and conversion system that supported a single sign-on web-browser interface. The interface was designed for use by people of all skill levels. ▪ Developed software to fulfill the needs of a half-dozen clinical (GCP) data conversion projects to use the web-interface; requirements definition, prototype design, implementation, unit and regression testing, documentation, validation team training and support.▪ Modified existing bioinformatic pipelines for clinical (GCP and CLIA) validation.▪ Created pipeline meta-data collection and reporting programs for clinical validation.▪ Developed a tool that detects and removes duplicate read alignments based on molecular barcodes. The tool reads a specially annotated BAM/SAM file, and produces a condensed BAM file, as well as statistical information and a Pileup file upon request.▪ Used the C++, Python, and R languages to implement software based on how well the language fit the problem at hand; all programs tested with the same custom framework.▪ Helped define the company standards for calculating values to support gene expression analysis. Designed software that uses these standards to produce clinical datasets for clients that do not want to incur the cost of custom development.Developed an effective software development process that employs:▪ Requirements communication documents and reviews, a validation process check-list.▪ A makefile system that requires all tests to pass before releases can be built.▪ A program-level test mechanism that has proved its worth a thousand times over by supporting test-driven development, and nightly and on-demand regression testing.▪ Standard methods to apply run-time coverage analysis, memory utilization, and memory leak analysis (using GCOV and Valgrind).

Development: C++ and Bash in Linux. Perl and R script conversion. Use of gcov and Valgrind.Responsibilities: Applied object-oriented software engineering principles to improve the efficiency, reliability, maintainability, and scalability of data processing pipelines.Created programs for data exploration, and translated scripts to C++ programs:▪ Utilized the bioinformatics data formats BAM, BED, FASTA, FASTQ, Pileup, and SAM. Used HTSLIB to work with BAM files.▪ Manipulated data to speed alignment, feed variant and CNV calling scripts, and to create reports for clients.Designed and supported infrastructure changes:▪ Planned for a future with bigger data and more customers.▪ Proposed a new SDLC process specific to NGS pipeline work.▪ Designed a framework that involved Git, a branching model, Gitolite, Virtual Machines, DEB release packages, Docker Containers, and Slurm. The framework was not adopted by the company, but two years later most of its components were in use.Wrote the Detailed Design document and Function Requirements Specifications for the Quintiles Comprehensive Cancer Panel (QCCP).

Development: C in Cygwin for VxWorks target, some C++ in Linux. Also Clearcase and Doxygen.MNP For India: Technical team lead on new development to support multimillion dollar Mobile Number Portability (MNP) project for customers in India. Detected and corrected flawed customer requirements. Feature framework designed for reuse. Requested and delivered ahead of schedule.MNP For Brazil: Technical team lead on all development for a multimillion dollar MNP project for a customer in Brazil. First use of the new Number Conditioning Framework. Requested and delivered ahead of schedule.Number Conditioning Framework: Engineer in charge of implementing the engine for a new number conditioning framework used for redesign of prominent past features and all new features of the main company product. Data-driven design. Object oriented implementation. Common user and coding interfaces save time in development, testing, documentation, and customer training.Subject matter expert for the TCAP, MAP, and CAP protocols.Author of several high-level and detailed design specifications.Problem Report coordinator for the protocol software group.

Development: C++, Java, and Bash in Linux. Also ANTLR parser generator, XML and XSD.Protocols: GSM/UMTS MAP and CAP (CAMEL), ANSI IS41, ANSI WIN, ITU TCAP, SCCP, MTP, SNMP.Detailed System RFP: Wrote highly detailed document that my customer could provide as an RFP to unknown and untrusted vendors to specify the desired product precisely. Requirement analysis and many discussions with customer management and engineers.System Log Monitor: Created a system log monitoring tool that reported SS7-over-internet link quality.
