My Journey From EE to IoT at Walmart’s DFW Tech Hub

Before I joined the team here, I had no idea how innovative a 50-year-old retail company could be.

Like most people, I had interacted with Walmart as a customer in stores and online but had never really thought about the systems and technology functioning behind the scenes to make the whole thing work.

As we officially open our new Walmart Technology satellite HQ in Plano, Texas, this week, I’m reflecting on my evolving, 20-year journey in tech — from building circuit boards to developing software to, now, exploring ways to apply advances in the internet of things (IoT), machine learning, object detection and other emerging technologies in the increasingly blended world of physical-digital retail.

Here’s a great example:

It might seem like a small thing, but spills are a big deal on the sales floor. So we developed a concept to help stores quickly detect spills, building a quick alert system that linked a camera with a Raspberry Pi and sensors that sent photos and data from the sales floor to the cloud. There, we deployed learning algorithms to analyze and build models that helped identify spills.

It wasn’t perfect – but it worked! And even though we won’t bring our prototype to life in stores at scale, we’re able to learn fast and apply those learnings to other projects — like using machine learning and IoT similar to our Raspberry Pi-based sensory concept to cut energy use and cost, all while keeping the temperature comfortable for associates and customers in our stores.

I’ve only been at Walmart four months, but it’s been a blast. I’m still blown away by the many different applications of emerging technology in something as simple as a retail store. But really, retail isn’t simple. It’s complex, the scale is insane and the industry is rapidly transforming. What an awesome time and place to experiment, innovate, fail fast and learn quickly.

It makes my brain happy, and I’m glad it’s happening here in the Dallas-Fort Worth area.
