I am preparing this book with Casa do Código to help designers and product teams adopt AI without outsourcing judgment. The draft focuses on practical workflow changes, source validation, ethics, and the parts of design that still need human review.

Impact beyond the screen

I design product experiences in real-scale contexts. A designer since 2019, in product design since 2021, across startups, scale-ups, and public products. I care about accessible, well-resolved interfaces with real business impact.

Thiago Xikota is an AI Product Engineer and Senior Product Designer: he works from problem to product in production, combining research, specification, design and building with AI agents under human review. A researcher at Lemme (UFSC), he published the AIMEDIA 2026 study on Specification Literacy and structural convergence. He is the author of Design na Era da IA, in production with Casa do Código, Chapter Lead of The AI Collective Florianópolis and founder of Xikota Design, a digital product design and building studio.

I talk about what I research and practice: how AI is changing the design profession and what to do so it works in favor of the people who design. Talk, workshop, panel, podcast or class. In person in Florianópolis or remote.

What I bring to the stage

Write me with as much context as you have: event or organization, date, venue or remote format, type of participation, topic, audience and conditions. I reply personally.

Hi, Thiago. I would like to invite you for [type of participation] at [event or organization]. Date: [date]. Venue or format: [venue/remote]. Topic: [topic]. Audience: [who and how many]. Conditions: [conditions].

My published research (AIMEDIA 2026) measured how interfaces generated without specification converge to the same pattern, and what specification changes about that.

Structural convergence: why AI makes everything look the same

Designers building product with AI agents, with judgment and human review. Current tools as the vehicle, principles as the subject.

From design to shipped product

What I learned auditing public design systems (277 non-conformities in my thesis, top grade) and ensuring WCAG 2.1 AA conformance in a global-scale product.

Accessibility as an acceptance criterion

The argument I am developing in the book Design na Era da IA, in production with Casa do Código.

DSGov forced me to redesign navigation for WCAG AA. The result wasn't just accessible: it completed 25% more. Accessibility isn't compliance, it's a design tool.

Constraints force clarity

At Bridge, each Bolsa Familia state has different rules for the MEC national student network. At Multidrop, two completely different user types shared one product with a hidden toggle that 4 of 6 testers couldn't find. I design for the scenarios most ignore.

Edge cases at scale are millions of people

At Multidrop, I built the DS from scratch to unify the experience for two very different user types in a single product. A design system isn't a library; it's a shared language that changes how the whole team makes UI decisions.

Systems outlast screens

How I think about design

I'm Thiago, a product designer born and raised on the island of Florianópolis, in southern Brazil, in a Japanese-Brazilian family (yonsei, fourth generation). I like understanding how things work and questioning what seems obvious. I spend my days turning messy problems into products people can actually use.

I started in design in 2019, before AI became a mandatory topic. Since then I've worked at Wellhub, Multidrop and Laboratório Bridge, where I helped design a platform for Brazil's Ministry of Education used by millions of students. I earned my degree in Computer Science at UFSC, with an exchange in applied computer science and AI at Sapienza, in Rome.

These days my work mixes design, product, code and AI. Not because I think every designer needs to become a developer, but because I like closing the gap between an idea and something working in the world.

I'm also the founder of Xikota Design, my design studio, and I lead The AI Collective Florianópolis, the first chapter in southern Brazil. I do research at UFSC, I'm writing a book (on its way with Casa do Código) and, in my free time, I teach Japanese music to young people at the local Japanese association.

I shipped an open-source brutalist design system from scratch  -  multi-platform tokens, 10 primitives, 8 patterns, a public docs site, and a Swift package  -  in 48 hours, using Claude Code as an operating system for product work. The result is the visual spine of Timeouts, my iOS social fitness app for time off the phone. This is not vibe coding: every component ran through a loop of brainstorming → planning → test-driven execution → code review, with skills, persistent memory, and subagents preserving context and product judgment.
