Making complex products feel simple.
I’m Carlos Custódio, a Product Designer specialized in enterprise UX and complex systems for fintech, B2B and SaaS.
Open to new projectsI started in 2009 as a graphic designer, moved into web design and front-end, and found my place in UX and product design. That path still shapes how I work: I care about the craft and I understand how things get built.
Over the years I’ve designed digital financial platforms across mobile apps, internet banking and backoffice, as well as ITSM, low-code and AI products, corporate investment banking, ticketing and agribusiness platforms.
I work across the whole arc: user research and usability testing, information architecture and critical flows, design systems built from scratch, and close alignment with PMs, engineers and stakeholders until it ships.

How I work
Four habits that show up in every project, whatever the size.
Decide with real data
User research, usability tests and heuristic reviews ground every product decision, not assumptions.
Make complexity clear
Dense, regulated workflows deserve interfaces that feel simple, accessible and easy to trust.
Design with engineers
A background in front-end makes handoffs a conversation, with constraints built into the design from the start.
Connect design to business
I align PMs, engineers and stakeholders so each design decision maps to a clear business goal.
Beyond the screen
Some things that keep me curious when I’m not designing.





Kind words from teammates
What it’s like to build products together.
“Handoffs with Carlos feel like pairing. The edge cases are already thought through.”
“Carlos brings research into every conversation without slowing the team down.”
“He made our design system something people wanted to use, not something they had to.”
