Vizio AI
Project Concept
At Vizio, we transform Google Chrome into an intelligent browser for the 6.5 million Brazilians with visual impairments, offering a solution with global scalability. Currently, screen readers are slow and confusing due to excessive ads and complex code. Vizio solves this: through Google’s Gemini AI, our extension interprets complex contexts in real-time, allowing users to simply communicate their intent instead of scanning the entire page. Our team, composed of two Software Engineering students and one Production Engineering student, combines technology and strategy to restore autonomy to those with visual impairments and build a truly inclusive internet for everyone, everywhere.

Leonardo Miranda Nunciaroni Team Lead RSVP Approved
Software Engineer at Conty
Arquitetou a integração com o Google Gemini 2.5 Flash, projetando os system prompts que permitem ao LLM interpretar estruturas complexas de DOM. Foi responsável pelo motor de "Intenção para Ação", que traduz linguagem natural (ex: "Escreva um e-mail para...") em ações executáveis de JavaScript dentro do navegador. Leonardo gerenciou o escopo técnico do projeto, garantindo que as respostas da IA fossem otimizadas para acessibilidade e eficiência cognitiva.
I started my journey in technology during high school, when I developed my first website, Ajuda+, a platform created to connect donors to charities. Before college, I also gained practical experience managing my own e-commerce business in the automotive sector. Currently, I am a Software Engineering student at PUC-Campinas and an intern at the startup Conty, where I have been part of the team since before the app’s official launch. Right now, I am focused on advancing my skills in Dart and Flutter.
I am interested in applying Software Engineering and AI to modernize traditional sectors and social impact projects. I seek to learn and collaborate on solutions that automate obsolete processes, using technology as an efficient tool to build a better future for society.
I’m currently a Software Engineering Intern at Conty App, where I dive deep into web development every day. Beyond my internship, I’m an active member of the PUC-Campinas IT League. We’re on a mission to bridge the gap between students and innovation by organizing tech events and making technology accessible to everyone across campus.
Matheus de Carvalho e Silva Esposito RSVP Approved
CEO at Cuida+
Realizou pesquisas com usuários para identificar os principais pontos de dor de indivíduos com deficiência visual e baixo letramento digital, traduzindo esses insights em requisitos técnicos acionáveis. Focou em garantir a conformidade com as diretrizes WCAG 2.2 e projetou o fluxo conversacional para minimizar a carga cognitiva. Matheus também desenvolveu os content scripts que simplificam o DOM antes de enviá-lo para a API do Gemini, garantindo que a IA foque em dados relevantes para a intenção do usuário, como as funções "Escrever" e "Caixa de Entrada" do Gmail.
I am a Production Engineering student at PUC-Campinas and a Product Lead passionate about transforming complex operational challenges into scalable social solutions. My approach is rooted in Lean thinking and process optimization, ensuring that technology serves a clear purpose and a validated market need.
I specialize in bridging the gap between software development and sustainable business models. Currently, I am spearheading the strategic development of Cuida+, a platform revolutionizing elderly home care, building on my previous experience creating user-centric solutions like Divide Aí. I believe the future of social impact lies in the intersection of data-driven engineering, AI, and humanized technology.
I am deeply interested in the intersection of AI and Social Impact, specifically how data-driven insights can revolutionize accessibility in Healthtech (Cuida+) and Fintech (Divide Aí). I’m looking to connect with mentors and collaborators experienced in Product Growth, GTM Strategies, and Scaling Startups. I am also keen on discussing Venture Capital and how to build sustainable, high-impact business models that bridge operational gaps in emerging markets.
I’m currently focused on Cuida+, a social impact platform that optimizes elderly home care logistics—my main project for this hackathon. Previously, I developed Divide Aí, a fintech solution for shared expense management. My goal is to apply Production Engineering (Lean & Process Optimization) to build scalable products. I’m now exploring how AI can bridge gaps in healthcare accessibility and financial organization, turning complex operations into seamless user experiences.
João Pedro Panza Mainieri RSVP Approved
Estudante at PUC Campinas
Responsável pela integração central da Web Speech API para o reconhecimento de voz em tempo real e síntese de fala (text-to-speech). Desenvolveu a lógica do ouvinte de comandos de voz dentro da Extensão do Chrome e garantiu a comunicação de baixa latência entre a entrada de áudio do navegador e a camada de processamento de IA. João também focou nos scripts de plano de fundo (background scripts) do Manifest V3 para manter o estado persistente durante a navegação.
