What I bring

Specialist depth.
End-to-end ownership.

I work where products are hardest to get right: regulated flows, operational tools and AI, where clarity directly reduces risk, errors and support cost.

    Complex workflows

    Enterprise, fintech and operations platforms, simplified without losing the depth experts rely on.

    AI product design

    Agent workflows, traceability and human oversight that make AI useful and accountable.

Background

From visual craft
to product strategy.

I began in graphic design in 2009, moved into web and front-end, and have spent the last nine years in UX and product design for fintech, enterprise SaaS, AI and logistics.

A front-end background shapes how I work: I design with engineering constraints in mind, document decisions in systems, and stay close to the team until the product ships.

Full background
Collaboration

Good products are
built together.

I partner with product managers, engineers and stakeholders from discovery to release, aligning every design decision with business goals and measurable outcomes.

Handoffs with Carlos feel like pairing. The edge cases are already thought through.
