B2B SaaS and enterprise product design for European clients: an energy trading portal, a B2B manufacturing marketplace, and a privacy compliance platform. • Designed and A/B tested two onboarding flows for a live iOS app. The longer, more personalized variant increased initial conversion by 30%. • Built design systems on three-tier token architecture, including full light and dark themes for an enterprise web portal, which turned later restyles into a token change instead of a redesign. • Restructured supplier onboarding for a B2B manufacturing marketplace and defined the free and paid tier boundary together with the founder. • Delivered 46 client engagements end to end: discovery, information architecture, user flows, UI, prototyping and developer handoff. 28% repeat clients. • Rebuilt the primary product card on an affiliate commerce site around a single action. Client reported click-through to the offer going from 5% to 32%. • Top Rated on Upwork with a 100% Job Success Score. Freelance work ran in parallel with my studio role until April 2026, and full time since.

Creative Mints • Tiempo completo

Jan 2023 - Apr 2026 • 3 yrs 3 mos

SaaS and crypto product lines, working alongside an art director, a project manager, two other designers and in-house developers. • Built 5 design systems from scratch on token architecture, proposed independently of client briefs, which held consistency across parallel engagements and cut rework between projects. • Led design on selected projects when assigned by the art director, coordinating an illustrator, a 3D designer, a motion designer and a second UI/UX designer: briefing each specialist, reviewing their output and integrating it into one coherent product • Ran 2 to 3 client engagements at the same time by starting each one from the system rather than from screens. • Presented each significant decision with a recommended direction and a second viable option beside it, tradeoffs stated. Final calls sat with the art director. The method was used often enough that presenting two directions became standard on client reviews. • Stayed on projects past handoff, resolving open questions with developers on calls through to release. • Worked in sprints with daily standups alongside PM and engineering.
