Smart Lipstick
Inclusive Beauty Through
Accessible Technology
The Smart Lipstick is a breakthrough beauty device designed to redefine how lipstick is applied, especially for blind, low-vision, and motor-impaired users. I led the design team through key fronts such as hardware and interface prototyping, user research, accessibility, and service flow, collaborating closely with fellow project leads.
What started as a bold innovation challenge became a fully functional prototype, blending universal design, assistive technology, and inclusive aesthetics. The device uses a self-moisturizing applicator that guarantees precise, effortless lipstick application, operated via a single button and supported by audio feedback and smart guidance.
By challenging the boundaries between body, device, and design, the Smart Lipstick became a symbol of speculative yet tangible futures. It was awarded the 2025 SXSW Innovation Award (People’s Choice), recognizing its global relevance and emotional resonance. The project was also shortlisted at the 14th Brazilian Design Biennial, positioning itself as a national benchmark and securing its place as a reference in inclusive innovation. So far, it has resulted in two patents registered with the Brazilian National Institute of Industrial Property (INPI): BR 10 2025 011461 5 and BR 10 2023 026289-9

In addition to winning the Innovation Award, in 2024 the Smart Lipstick was also shortlisted at the 14th Brazilian Design Biennial, positioning itself as a national benchmark and securing its place as a reference in inclusive innovation. Beyond innovation, this is a product about dignity, confidence, and independence — beauty that doesn’t exclude.

Rumpi
Empowering independent
artists in Brazil
In Brazil, being an independent artist is more than a creative choice, it’s a daily battle against an opaque and fragmented music industry. Royalty collection is complex, platforms are hard to navigate, and managing a sustainable career often feels like a solo mission. Rumpi is here to change that.
Currently in development, Rumpi is a new platform designed from the ground up to empower independent musicians, helping them track royalties, understand performance data, and grow their presence across streaming platforms.
What makes Rumpi unique isn’t just its technology, it’s the mindset. Every interaction, every dashboard, every revenue model has been shaped to serve the needs of the small artist, not the mainstream star. It's about building a more transparent and inclusive music ecosystem in one of the most culturally rich, yet economically unequal, countries in the world. Our goal is not just to support artists, it’s to reshape the industry for them.
The platform is set to launch in the second half of 2025. If you're curious or want to collaborate, feel free to reach out.

Lenovo Libras
The worlds first AI sign
language translator
In a world that’s increasingly digital, accessibility shouldn’t be an afterthought, it should be a foundation. But for millions of deaf and hard-of-hearing people in Brazil, interacting with digital interfaces still means facing daily barriers. Lenovo Libras was built to change that.
Created in partnership with Lenovo and nominated as a finalist for the SXSW Innovation Awards 2024, this solution brings Brazilian Sign Language (Libras) to the heart of technology. Through AI and inclusive design, the tool translates interfaces and digital content into Libras, creating a more equitable digital experience for one of the most underserved communities in the country.
But this isn’t just about translation, it’s about dignity, autonomy, and systemic change. Every interaction in Lenovo Libras was co-designed with the deaf community, ensuring that the experience feels intuitive, empowering, and culturally accurate.
This project is a statement: innovation means inclusion.

Bixby
Expanding voice interaction
through Human-Centered AI
In partnership with SiDi (Samsung Institute for Development of Informatics), I was part of the evolution of Bixby, Samsung’s voice assistant. Our team focused on designing how users created and customized new voice commands in a more intuitive and scalable way.
We conducted continuous user interviews across all of Samsung’s global innovation centers, including teams in the UK, USA, Brazil, Poland, South Korea, and others. The biggest challenge was aligning how different cultures and languages structure communication, so we could build a voice assistant that truly worked across linguistic and cultural boundaries.
The solution wasn’t just technical, it was collaborative. We built a platform designed specifically to empower linguists and conversation designers from all these global hubs to define Bixby’s commands, responses, and functionalities in their own languages and cultural contexts. This ensured that the assistant felt native, respectful, and usable, no matter where or how it was accessed.
Our work combined Conversational UX, AI integration, and interaction design, all grounded in a human-centered approach that valued simplicity, user control, and cultural nuance. This wasn’t just about making Bixby smarter, it was about making it inclusive, adaptive, and truly global.

DATES - A platform to create new business between startups, investors and companies
DATES was born from a bold idea inside CESAR’s intra-entrepreneurship program, where I joined forces with five brilliant colleagues for an intensive 6-month innovation sprint, a competition that we proudly won. The vision? To rethink how entrepreneurs connect with investors. The result was DATES: the only platform in Brazil that uses data analytics and intelligent matching to connect startups with potential investors in a meaningful, strategic way.
Through a combination of predictive analytics, founder profiling, and investment behavior mapping, the platform goes beyond pitch decks, it understands compatibility.
Today, DATES is the official investment tool used within CESAR’s own Ventures division, and it has already facilitated dozens of strategic connections between startups and capital. It’s a living product, shaped by real needs from both sides of the innovation ecosystem.
Built from scratch with a design-driven mindset, DATES emerged as a result of lean experimentation, user research, and deep collaboration between design, tech, and business teams.
More than a tool, it’s a matchmaking engine for innovation.
The founders validated the MVP at MangueBit, the largest startup event in Northeast Brazil.
