Provide data analytics, data management and visualization to data-enabled projects. Evaluate existing systems and recommend upgrade paths.● Build back-ends and visualizations for water quality and water usage data. These projects collect data from IoT devices and REST APIs, store it in MongoDb, and expose REST APIs to serve the data in various ways to browser-based dashboards. ● Wrote an image generator that creates smooth heatmaps from sparse, non-uniform data. For example, to visualize dissolved oxygen levels as a function of both depth and time, a 2-D heatmap is created. The source data has approximate sample periods of one hour and one meter, but they are neither exact nor consistent, so the data points do not fall on a regular grid. To shade the heatmap, the data points are triangulated using Delaunay or a heuristic. The points are assigned colors according to their dissolved oxygen levels, and the triangles are shaded with linear interpolation using barycentric coordinates.● Evaluate SCADA and industrial control systems and recommend upgrade paths. Evaluated C/C++ process control code to assess the difficulty of porting to IEC 61131-3.

Software engineer and management veteran with a passion for hands-on engineering. I draw my energy from creating and teaching. I like to be able to see a direct line between my contribution and how it provides value to the customer, generates revenue for the company, and grows the people in the organization. My ideal job is one where I get to work closely with the end user across all phases of the project. I thrive on the energy that comes from being part of a high-functioning team, both as a leader and as a peer. My ideal environment is working shoulder-to-shoulder with other engineers, scientists, marketers and management.

● Wrote machine-control and user-interface software for Illumina's sequencing instruments. All were developed with .NET and written in C#. Earlier solutions used Windows Forms, while later ones used WPF and MVVM.● Rewrote aging codebases using modern practices, including SOLID principles and TDD. Added mocks and unit tests, achieving test coverage as high as 90% in certain modules.

Director, Software DevelopmentAssociate Director, EngineeringSenior Manager● Lead a department of 50+ highly-skilled software developers with diverse expertise. My group developed the software that runs Illumina's instruments, designs assay probes and performs the data analysis. The team developed two of Illumina's web-based applications: DesignStudio and BaseSpace. In addition, the team developed numerous systems that Illumina uses internally, including their own LIMS, manufacturing automation robotics and tools for instrument manufacturing.● In 2014, Illumina shipped the HiSeq X—the DNA sequencer that ushered in the $1000 genome. The programmers on my team wrote all the HiSeq X software, including the user interface, motion control, chemistry automation and image analysis.● In 2011, I introduced Scrum to the Software Engineering department. I brought in instructors and, over the course of the year, got over 150 people trained as Scrum Masters and Product Owners. Active projects were transitioned to Scrum, and all new projects used it.● Acted as a Chair of the Peer Technology Review Committee. In addition to convening the review, the chair is responsible for writing and publishing the minutes. This requires assimilating and understanding information across the full range of technical and scientific disciplines that go into Illumina’s products. The information must then be digested into a succinct summary that is published to C-level executives.

● Authored image-assembly software used for failure analysis during product development of new microarrays and their assay kits. As the density of Illumina’s microarrays increased, I was forced to write all my own pixel-level image-manipulation code because of Microsoft’s 32k-pixel limit on image dimensions.● Software Architect and Project Lead for a five-person team that implemented control software for Illumina’s Big Bird DNA synthesizers. These machines perform automated wet chemistry for high-throughput synthesis of oligonucleotides. Hardware devices include a motion controller, an I/O controller, custom-built electronics, pneumatics, fluidics and cameras. The software provides the user interface as well as the top-level control over the hardware. It was written in C#.    • Designed the overall architecture of the software and documented it in UML, Visio, PowerPoint, and Word documents.    • Led the development of version 2 of the software. The improvements in this version increased reliability and utilization to the point that Illumina was able to scale back from running the Big Birds 24/7 down to a single, five-day shift.● Designed and implemented many of the core framework libraries that have gone into Illumina's products for over a decade:    • Finite state machines for communication with the hardware. These provide multithreaded access with guaranteed handling of error responses and timeouts. An interactive, graphical state diagram viewer provides flexible runtime testing and troubleshooting.    • Finite state machine-backed user-interface library for complex wizards.    • Custom touch-friendly GUI controls including buttons with pluggable look-and-feel, and interactive, graphical representations of parts of the Big Bird machinery.    • Boolean logic classes that allow circuits to be built and output to a Visio diagram.    • User-interface controls that, when disabled, provide an auto-generated tooltip explaining why.

● Software Architect for a five-person team that implemented the control system for OMM’s 3D photonic cross-connect switch. This project was a hard-real-time, multiprocessor application. It was written in C/C++ and ran under VxWorks on Motorola MCP750 PowerPC boards in a CompactPCI chassis:    • Designed the overall architecture of the software and documented it in UML.    • Wrote modules that implemented the real-time control, multitasking, interprocessor communication, online numerical optimization, signal processing, and polynomial fitting.    • Resulting software successfully controlled the optical subsystem to switch fiber-optic signals.     • Demonstrated the system to customers and strategic investors.● Set up and ran optics-bench experiments at the outset of the 3D project. Control systems were prototyped using MATLAB and dSPACE. Set up a variety of data-gathering stations using National Instruments cards and LabVIEW.● Contributed micro-electromechanical systems (MEMS) designs to R&D runs for OMM’s 2D product line. Evaluated CAD/CAM software for modeling and simulation of MEMS.

● Part of a four-person team that implemented next-generation control software for CNC machine tools. The user-interface was designed using the Contextual Inquiry methodology. It was written in Java and it communicated through a DLL written in C to control the hardware.     • Wrote original GUI controls, filesystem support, and hardware I/O.    • Implemented the product’s text-editor and the 3D wireframe graphics display. Both were written from scratch entirely in Java.    • Project team received the Yaskawa President’s Award for Outstanding Achievement and a cash bonus.● Wrote the expression parser and symbol table of an integrated development environment for motion control. That software was written in Visual Basic and C++. The parser was generated with Anagram.
