From these tests, students critically analyzed different structural coverage criteria in terms of fault-finding effectiveness and contrasted it with both requirements coverage and different test input selection criteria.Software Engineering I: Overview, Requirements, and Modeling (SEng 5801) -- Fall 2013, Fall 2016Software Engineering I (CSci 5801) -- Spring, Fall 2012* Introduced Agile processes and practices (e.g., Scrum and planning poker) to classes of 30-60+ students, showing them how to select and apply the techniques best suited to their project goals.* Redesigned the course assignments to provide practical experience in producing a product using test automation to replicate realistic developer-tester interactions.* Taught design patterns to a class of 80+ students and inspections to a class of 30+.* Tutored students in the use of NuSMV to model and verify requirements.

Quality Assurance and Process Improvement (SEng 5852) -- Spring 2016, Spring 2017* Taught objectives-based process evaluation, metrics-driven process improvement, and Agile/Lean techniques to professional masters students seeking to become leaders in the field.* Coached students in Agile and Lean practices; helped students apply these practices in their current jobs.* Wrote assignments to get students to critically analyze processes, including those they use at work, and develop improvement plans.* Tutored students in technical writing to improve their communication and reasoning skills.

* Developed RESTful services (Spring) to migrate customer data to new Configure, Price, Quote (CPQ) software.* Improved product quality by reviewing, testing, and refactoring other parts of the code base. Identifying potential sources for data inconsistencies, I paired with other developers to improve input validation and data integrity.

* Created tool (Python3) to construct new programs from code clones to detect server attacks.* Developed iNeuron, an iOS app (Swift) that teaches high school students neuroscience by experimenting with neural circuit construction.* Designed and crafted means to discretely map a network using a widely-deployed embedded controller, providing compelling support for our proposed security improvements.* Explored means of securing and re-purposing an embedded controller to monitor the integrity of a server.

* Developed RESTful services (JAX-RS) for data extract-transform-load product (InfoSphere DataStage).* Established team quality practices---including automated testing (JUnit) and regular code reviews---and integrated additional quality checks/metrics into the build (SonarQube, Checkstyle, JaCoCo).* Trained globally-distributed team in Agile practices and test input generation strategies.

* Devised new CPU utilization metrics that account for simultaneous multi-thread (SMT) loads to simplify customer system capacity planning on IBM i. Using knowledge of POWER8's processor pipeline, I devised test programs (C++) that would replicate different pipeline loads, then executed, collected, and plotted the utilization of each (Python2, matplotlib, numpy) against the known pipeline load (the oracle).* Evaluated the potential market for FPGA accelerator support on IBM i, leading to product offering changes.

Existing test coverage tools instrument the application in order to assess coverage, potentially introducing faults. This poses a risk for safety-critical systems. Using a novel, multi-core processor architecture (Ex-Mon simulated in SIMICS), we showed how to non-intrusively measure the test coverage of an uninstrumented application; allowing us to test the actual application to be deployed. We initially demonstrated the architecture's ability to non-intrusively measure Modified Condition/Decision Coverage (MC/DC) and later expanded it to include other forms of coverage like statement coverage.

* Produced IBM i storage debug and diagnostics tool (C++) to improve customer-site support.* Created prompt program (ILE C++) to enhance the high availability product’s command-line user experience.* Developed command-line tool for cluster resource manipulation and management.

* Led team and developed Java tool to package and release the IBM i OS and product images (the golden masters) to distribution centers; reducing release times by 1-2 months per product set and saving 2 person-years of effort annually.* Proposed unified installation tool for IBM i, AIX, and POWER Linux network installs using VIOS to bootstrap the process. Defined IBM i network install requirements and designed new tool.* Supported organization-wide Agile process adoption effort by aiding in the process selection, advising on tool capabilities, and training developers.* Led a university capstone team and intern in creating a new web client for managing software images.* Trained department to use Scrum (Agile) by convincing stakeholders of its benefits, instructing developers one-on-one, and demonstrating the process on my own team.* Enhanced and maintained business-critical software image management system (C++), its clients (Java, JSPs, EJBs), and OS modules that packaged and automatically installed IBM i systems over the intranet.* Area's (directorate's) top performer in 2009.

* Enhanced and extended business-critical software image management system (C++), its clients (Java, JSP, EJB), and OS modules that packaged and network-installed the IBM i OS and middleware (DevOps).* Led team and developed IBM i OS and middleware packaging and release tool (Java); reducing release times by 1-2 months per package and saving 2 person-years of effort annually.* Engineered Java web service to transform and transmit support information to customer distribution centers, resulting in faster dissemination of critical information such as defective fixes.* Supported organization-wide Agile process adoption effort; aiding in process selection, advising on tool capabilities, and training developers (Scrum, TDD, Planning Poker).

Introduction to Programming I (CSE 231)Semester: Spring 2008* Taught and tutored first-year students in Python2 programming.* Led weekly lab sessions consisting of over 25 undergraduate students. During these sessions, I guided students through an exercise to improve their understanding and answered questions related to the homework and exams.* Graded assignments (code inspections) and managed the course website.College Algebra and Trigonometry (MTH 116)Semester: Fall 2007* Led twice-weekly recitation sessions consisting of over 25 undergraduate students. During these sessions, I instructed students using practice problems to reinforce their understanding of the concepts taught in class.* Tutored students both in office hours and at the math learning center.* Graded assignments

* Automated the installation of groups of fixes during lab-system install, saving time by eliminating the need to manually install fixes.* Integrated bug-fix process support system with new requirements management tool (ClearQuest).

* Designed and implemented a Java web service (and modified clients) for guiding developers through the fix process, improving fix quality and eliminating our need for a legacy mainframe system. * Translated prior fix process guidance to work with the new tool. * Generated program specifications from an existing fix tool—using exploratory testing and code examination—to support a web-based re-implementation.* Debugged and repaired the image management system's administrative tool.
