Managed a team of up to eight Software Developers doing Embedded LinuxTeam members are in Sunnyvale, India and Russia.Planned a major new feature and my team completed on scheduleOn change review board. Assigned bugs to developers and reviewed their workTaught new developers how to do work with Embedded Linux. Provided how-to documents covering everything from booting devices to GUI debuggingWrote functional specifications for new features

Ported and improved kernel drivers for Ethernet, WiFi, GPIO, USB, and SLICBrought up five new Embedded Linux boards.Wrote several applications from scratch including a custom network manager, health monitor, core dump manager, and reflashing tool.Designed and documented a development host to be used by all developers. Can be hardware or virtual machine. Can be ready to build code in just a few minutes.Combined two separate source code branches into one in order to build from common code. Used it to release new code on old Telo and new Telo at the same time. Development continues on the combined main branch. Supports six board models across three kernels and three toolchains.Set up and maintained an internal wiki. Wrote literally hundreds of topics.

Next Generation SmartServer The SmartServer is a versatile smart energy manager that connects control devices to IP-based applications Bootstrapped and implemented from the ground up a complete Debian system.Created an Ubuntu-compatible toolchain. Designed and built native Debian packages for proprietary in-house code.Implemented NFS-mounting root file system for development use.MCNA lower-end, low cost embedded Linux platform to provide point-to-point metering Implemented a buildroot/busybox root file system.Used PIC18F1450 to provide a composite USB/Serial Port bridge and remote general-purpose I/O. Wrote the Linux kernel driver to communicate with the microcontroller.Edge Control Node for Smart MeteringThe Edge Control Node is a modular Linux-based system that primarily collects billing data from Echelon Smart Meters over the power lines. Team leader for development of the product’s software platform. Company expert for Linux platform topicsManaged remote consultants working on network and raw NAND flash drivers. Wrote scope-of-work and tracked their progress. Integrated resulting drivers into the system.Selected the development tools.Documented best-practices and coordinated use of virtual machines by up to eight developers to develop application code. Performed processor board bring-up, including JTAG debugging, and u-boot bootloader.Designed, and implemented the root file system using buildroot/busybox and scratchbox2.Developed a build system to create the smallest possible delta upgrades using a union file system variant.Integrated and configured the Linux kernel to support application requirements.Wrote a Linux device driver to manage general purpose I/O, including i2c I/O expanders.Designed PXEBOOT and a web-based system to completely re-flash units from the network. This allows quick parallel updates to hundreds of units installed in System Test labs.Implemented utilities in C for Manufacturing Test.

Streetlight Bridge A ZigBee radio link is used to link power line segments for networked street lighting.Developed a monitor program on the TI MSP430 to allow manufacturing test to serialize, calibrate and configure the board and to exercise the RF Transceiver.Implemented a Windows DLL to interface the monitor to National Instruments TestStand. Provisioning ToolA Windows-based GUI with a database back-end to allow editing and managing Smart Meter configuration data. Designed and implemented:The user interface using Delphi;XML classes to model the meters;Forms for editing configurations and persisting to an Access database;ATL-derived COM objects for communicating with the product’s Data Concentrator engine;Command-line tools for testability.

NodeBuilderAn application development system for Echelon Neuron ChipsPrototyped the user interface, focusing on Microsoft User Interface guidelines.Ported previous generation debugger API to Win32.LonPoint ApplicationsDistributed sensors and control points based on the Echelon Neuron Chip. Defined a reference design for an HVAC air handler to show proof-of-concept.Defined and implemented software logic blocks packaged in small hardware modules to provide distributed I/O close to sensors and actuators. For example, an analog input function with linearization constants and a PID controller.

Designed many of Echelon’s system products including: Control Modules, Network Interfaces and the LonBuilder Neuron Chip Emulator.

Hardware Architect and Technical Team Lead for Switch Fabric ConversionResponsible for the hardware architecture and design.Provided technical leadership for a team of eight Hardware Engineers on this project that allowed customers to move existing line cards into a Siemens Hicom telephone switch.Implemented key state machines.Team Leader for Data Com ProjectSupervised a cross-functional team of about twelve professionals to take the project from kick off to release to manufacturing. Presented project status to executive staff on a regular basis.Primary designer of the ASIC that formed the core of the data com adapter. Provided direction to two other hardware engineers on the project. The first iteration of the chip worked.
