Juan Peña · Sr. Product Designer · Enterprise B2B
I work on enterprise finance and procurement: expense reimbursement, approvals, and supplier workflows. The unglamorous, high-stakes tools nobody chooses to use but everybody depends on.

One expense platform handling 824,000+ reports a year across Walmart US Stores, Sam's Club, and Supply Chain.

Led UX for Walmart's internal procurement platform and its native MyWalmart extension, connecting search, ordering, approvals, tracking, and store access across a multi-year roadmap.
For nine-plus years, I have owned enterprise operations platforms end to end, currently four connected products used by tens of thousands of associates. I stay close to the craft on purpose, because that is how I keep enough context to make good calls across a system that large. It is the direction I want to keep growing in, toward a Principal-level role.
Outside of work, I have put more than 4,000 hours into Destiny 2. Gaming is one of the things that have always been there for me, and all that exposure to interfaces has actually helped me out a bit in understanding how to make UI easier to navigate.
