Sérgio Fontes
Staff Product Designer II at Stone
Pernambuco, Brazil
Summary
👤
Senior🎓
Top SchoolSérgio Fontes is a Staff Product Designer with 11 years of experience crafting user-centered products and building design teams across fintech, e‑commerce, and edtech. At Stone he moved from lead design to staff level, shaping payments and merchant-facing products like an online catalog that translated research-backed hypotheses into new revenue streams for Brazilian micro and small merchants. He combines hands-on design execution, front-end engineering empathy, and design ops to seniorize squads and scale consistent component systems—skills honed earlier at VTEX and in a designer-engineer hybrid role at Guava. Comfortable in ambiguous, mission-driven contexts, he blends aesthetic rigor with business strategy and a bias for iterative validation. Based in Pernambuco, Sérgio brings a regional perspective and daydreamer’s curiosity to practical product solutions that reduce cost and unlock market fit.
