The Teams Behind Walmart.com's Cross-Border Expansion

A customer might search for a cookware set. Minutes later, it’s in their cart. A few days later, it’s at their doorstep. To the customer, the experience feels straightforward: find something you like, add it to your cart, check out, wait for it to arrive.

Making that experience feel effortless required teams across Walmart and Walmart Global Tech to solve one difficult problem: How do you give customers more choice without giving them more complexity?

For the associates building it, that meant bringing together search, translation, commerce, fulfillment and supply chain to make international shopping feel familiar.

This became the team's blueprint: solve the right customer problem, bring together the right people and build the right foundation.

It Started With A Question

The work kicked off with a question: What customer problem are we trying to solve?

That question became the starting point for Vikash Pansari, one of the product leaders helping guide the program, and his team.

"We spent a lot of time identifying the right customer problem, the right capabilities and the right roadmap," he said. "Once we understood the experience we wanted to create, we could bring together the right teams to build it."

Customers wanted access to more products without added friction, along with transparent pricing, reliable delivery and confidence that Walmart would stand behind each order.

From there, teams across Walmart worked to make it possible.

Making Search Feel Natural

Before Walmart.com expanded to customers in Mexico, another team had already solved one of the biggest barriers to shopping on the site: language.

"We were looking to expose non-English speakers to the same mature search experience English-speaking customers already had," Leo Lezcano, director of engineering, AI/ML said. "The goal is to make the transition from a customer's buying intention to adding an item to their cart as seamless as possible."

Rather than focusing on translation alone, Leo's team measured success by whether customers could find the products they wanted.

"We envisioned a Walmart experience that offers the items that make you feel at home," Leo said. "Whether you're visiting from abroad and looking for a particular spice, or your grandmother is searching for a fruit or meat cut she's always known by another name, we want you to be able to find it."

The work eventually became part of Walmart.com's expansion to customers in Mexico.

"From the beginning, we weren't thinking about translation as a one-time solution," Nicole Mcnabb, head of ML science said. "We were building a platform that could grow alongside the business — supporting new languages, new experiences and, ultimately, new markets."

Earning Customer Trust

Access only matters if customers can discover the right products. As Walmart Marketplace expanded its assortment, teams focused on making sure customers saw products they could actually purchase without making the experience feel overwhelming.

"One of the problems I always came back to was eligibility," said Sumit Sehgal, group director of Cross Border Solutions. "If a customer comes to Walmart.com, we want to show them the items they can actually shop for. If they find something they love only to learn it can't be shipped to them, that breaks trust."

The team designed the experience so customers only saw products they could actually buy.

Removing Complexity

The Walmart.com team took a different approach, rethinking the entire shopping journey to answer questions before they became concerns.

"The hardest part wasn't building cross-border capabilities," Nitish Agarwal, product manager said. "It was deciding how much complexity customers should see versus what Walmart should handle on their behalf."

Those decisions shaped the shopping journey: Can this item ship to me? How much will it cost? When will it arrive?

Nandhutha R S and her software engineering team were thinking about what shoppers needed to know and what wasn’t relevant to them.

"A customer in Mexico landing on Walmart.com doesn't have the same context as a U.S. shopper," she said. "If we showed experiences that didn't apply to them, it created confusion."

Nandhutha helped adapt the existing Walmart.com experience, introducing homepage messaging, fulfillment badges and transparent pricing while removing features that weren't relevant for cross-border shoppers.

"Our team worked to keep customers aware and informed at each step of the journey," Nandhutha said. "By the time they reached checkout, they already had what they needed to feel confident."

Making that happen required teams to coordinate pricing, shipping, import fees, fulfillment, analytics, accessibility and testing.

"The goal was not to make international commerce invisible," Nitish said. "It was to make the total cost understandable and predictable."

Delivering on the Experience

Then came the moment everyone had been working toward: the first production order.

Watching that order move through Walmart Fulfillment Services (WFS) was the moment the project became real for Harish Pagadimarri, a senior software engineering manager, and his team.

"The first seller onboarding. The first item published. The first real order in production. Then we went to the fulfillment center and watched that item begin its journey to the customer's door. Months of late-night calls, architecture debates, sprint reviews, escalations and integrations — all of it compressed into one box going out a loading dock."’

"For customers, it's magic," Harish said. "For us — we know how the magic works." 

Building for What’s Next 

Every group solved a different customer problem while building something the next team could build on.

"We were very deliberate from the start," Sumit said. "We didn't want to build this as a one-market solution. We wanted to build it in a platform way so we could expand one country after another."

Vikash believes that's what made the work stand out. "The scale was huge," he said. "We touched the customer journey, seller journey, fulfillment and compliance. It took the right people with the right skills coming together to build it."

Today, customers in Mexico can shop Walmart.com with access to hundreds of thousands of additional products. The work behind that experience is already helping shape what's next.

Every search, checkout and package delivered across a border reflects the work of hundreds of associates who turned months of collaboration into a customer experience that feels remarkably simple.
