Veo Robotics builds FreeMove, a system that uses time-of-flight (ToF) sensors to monitor industrial workcells, enabling safe interaction between robots and humans. FreeMove is ISO 13849 certified for PLd, Category 3. The computing platform uses two Linux servers and an RTOS running on a safety-certified TI MCU.As an early engineer at Veo, I have been heavily involved in designing and building FreeMove from concept to realization. I advocated for an engineering culture focused on sound software development principles which enabled us to achieve a 13849 certification while using modern tools such as The Yocto Project, C17, C++20 and Python 3. As an individual contributor, subsystem architect and technical lead, I authored or reviewed a substantial portion of all software developed at Veo.- Identified and incorporated the Yocto Project Rocko release as the core OS and development environment, then maintained internal Yocto layers through the Nanbield release.- Designed and developed platform services and libraries that provided the core communication and synchronization capabilities between all FreeMove components.- Designed request/response and streaming protocols for communication across the Linux servers, ToF sensors, and the TI MCU. Authored C++ and Python implementations of these protocols.- Mentor and principal authority on Python across all engineering teams.- Technical lead of up to 5 engineers.- Led the design and implementation of CI, which required every commit to be built, linted and tested prior to hitting mainline. Furthermore developed whitebox integration testing infrastructure for the full system testing.- Incorporated Podman/Bubblewrap containers into development and test environments.- With CTO, VP Engineering and other technical leaders, authored System Design Document, ensuring clear system requirements for compliance with safety standards.- Developed Linux device driver for a custom FPGA, processing 9 streams of UDP packets.

- Google Summer of Code Mentor - 2017, 2019.- Member of Gentoo/Cluster and Gentoo/Science teams.- Maintained the core HPC stack and implemented support for multiple MPI implementations to be active simultaneously.

Kuvée built a smart wine bottle and capsule that kept wine fresh for 30 days. The wine dispenser gave users more information about the wine they were drinking, tracked preferences and let them order more wine. Until August 2015, I was contracted to bring-up Yocto on Kuvée's first board. After joining I was primarily an individual contributor but also led the systems/backend team.- Built Yocto-based OS for iterations of custom AM335x boards including software for release management, device manufacturing/testing and OTA updates.- Architected an IoT framework for the distributed fleet of dispensers, collecting device usage statistics and supporting secure customer interactions with their profile and the Kuvée store.- Designed and implemented the backend services for dispensers and the web store, enabling customer accounts, wine subscriptions and one-off orders, wine recommendations, inventory control, etc.- Implemented Qt/C++ libraries allowing the dispenser to interact with Kuvée infrastructure and wine capsule RFID tags.- Championed unit/integration testing, documentation and code review.- Managed team of back and front end engineers.

RIFT.io built cloud-based platforms to automate the deployment and orchestration of virtualized network services and functions.- Designed Virtual Compute Subsystem and Hierarchical Resource Manager.- Extended CoreFoundation event loop and implemented plugin API for Python3 and Lua.

Acquired by Bio-Rad in April 2014, GnuBIO developed a fast droplet-based sequencing platform that allowed workflows to complete in hours instead days.- Architected behavioral controller and application messaging layer in C++ and Python utilizing Tornado, ZeroMQ and Protocol Buffers.- Implemented web-based UI for developers, biologists and engineers.- Developed applications for TDI camera image acquisition, image analysis, biocontrol, experiment definition management and drop manufacturing.- Mentored junior software team members.

Rethink Robotics built low-cost, collaborative, force limited robots that be easily programmed without a teach pendant. The first robot, , was particularly popular in research universities.- Designed, implemented and maintained the core robot OS and software release management tools as well as providing support for internal customers.- Core developer on SDK team which provided researchers with a simple, uniform interface to control the actions and behavior of the robot.- Created the persistence and communication infrastructure that integrated the UI with the other pub/sub components of the robot.- Implemented foundational framework libraries utilized by the UI team.

QT based UI development and image processing.

Brontes built the first FDA 510(k) approved, in-mouth digital oral scanner which, after 3M acquisition, became the LAVA Chariside Oral Scanner. The C.O.S. enabled lab production of customized dental restorations such as crowns and implants.- Developed and maintained the core OS which included tooling for software release management, manufacturing installation and acceptance testing, device update implementation and management and license compliance checks.- Provided Linux expertise to a team of application, visualization and hardware engineers.- Developed Linux device driver and userland library supporting a custom FPGA.

- Built and administered mixed HPC clusters and a pvfs2 storage cluster.- Aided University researchers in the creation, compilation, and optimization of in-house and commercial HPC applications.- Designed and developed automation for provisioning and updating nodes with mixed operating systems and applications, on demand, in a clustered environment.- Developed HPC resource accounting backend.

Completed the data processing for 10 years of runway condition analysis for all state airports.Assistant Project Manager, Calais Branch Study.
