Hello

My personal goal is to create clever, beautiful things that help people and make the world better.

I am a driven and self-directed individual who works to continuously improve my understanding of the world and make it a better place. When faced with a problem I dive in to understand the true issue and find the right solution. I have demonstrated this approach both with deep technical investigations as an individual and by leading cross-team efforts to find gaps in process and product definition.

I have a decade of experience in electronics design and manufacturing for medium to high volume IoT devices. I have designed RF modules, evaluation boards, battery powered sensors, antennas, and IoT gateways. Continuous learning and sharing knowledge with others is one of my core values. For me part of doing a job right means making sure I share what I learn with my peers and documenting the process so anyone can take it over. I am a firm believer in tearing down knowledge silos and collaborating with other teams. When possible I talk directly with the teams and line operators who build the things I design so I can do the best design for manufacturing possible.

My current title is Senior Systems and Infrastructure Engineer on the Rigado team at Walmart Global Tech focusing on hardware and software IoT solutions. Prior to being acquired by Walmart in 2025 I had been a Senior Hardware Engineer and other titles at Rigado since 2016, with a brief stint at u-blox. What has made my time at Rigado special has been the team's high trust in each other and the autonomy I have had to pursue creative and unusual solutions. A frequent complement I have received from my long time manager at Rigado has been:

"I don't lose any sleep over projects I know Nick is working on"

While I have enjoyed professional success I also feel I could do more to use my skills to improve the world. I am always on the lookout for education and mentorship volunteer opportunities as well as short term design and project management contract opportunities for humanitarian and environmental causes.
