Juan Peña · Senior UX Designer · Enterprise B2B

UX for systems that companies can't afford to get wrong.

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.

A bit about me

I have spent twelve years in design and the last five in product. At Walmart Global Tech, I work across four connected procurement 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.
