I have worked across financial technology, enterprise software, and internal platform development, delivering products that balance performance, usability, and reliability. At IBM, I built applications using IBM Watson cognitive services, created conversational trees for chatbots, and developed internal pages that met high design and accessibility standards. In later roles, I helped improve developer experience and product quality by introducing TypeScript, design systems, visual regression testing, strict type checking, and stronger CI practices. I have also contributed to migrations to React and Next.js, improved E2E testing suites, and built responsive interfaces for complex workflows such as payroll financing, registration, and account management. I enjoy collaborating with product, design, and backend teams to create polished user experiences, and I am comfortable working with modern JavaScript ecosystems, APIs, testing tools, and cloud-based services. I am based in São Paulo, Brazil, and I bring a full-stack mindset with deep front-end expertise, especially in React, TypeScript, Node.js, and scalable UI architecture. ## Professional area ### [Developer & Engineer](https://jobicy.com/resume-category/dev.md) ## Skills ### [Agile](https://jobicy.com/resume-skill/agile.md)[AWS](https://jobicy.com/resume-skill/aws.md)[CI/CD](https://jobicy.com/resume-skill/ci-cd.md)[CSS](https://jobicy.com/resume-skill/css.md)[Docker](https://jobicy.com/resume-skill/docker.md)[E2E Testing](https://jobicy.com/resume-skill/e2e-testing.md)[Express.js](https://jobicy.com/resume-skill/express-js.md)[Git](https://jobicy.com/resume-skill/git.md)[JavaScript](https://jobicy.com/resume-skill/javascript.md)[Linux](https://jobicy.com/resume-skill/linux.md)[MongoDB](https://jobicy.com/resume-skill/mongodb.md)[Mongoose](https://jobicy.com/resume-skill/mongoose.md)[Next.js](https://jobicy.com/resume-skill/next-js.md)[Node.js](https://jobicy.com/resume-skill/node-js.md)[PostgreSQL](https://jobicy.com/resume-skill/postgresql.md)[React](https://jobicy.com/resume-skill/react.md)[Redux](https://jobicy.com/resume-skill/redux.md)[Rest API](https://jobicy.com/resume-skill/rest-api.md)[Scrum](https://jobicy.com/resume-skill/scrum.md)[Tailwind CSS](https://jobicy.com/resume-skill/tailwind-css.md)[Testing](https://jobicy.com/resume-skill/testing.md)[TypeScript](https://jobicy.com/resume-skill/typescript.md) ## Education Jan 2014 - Dec 2015 Bachelor of Computer Science @ Universidade São Judas Tadeu Jan 2011 - Dec 2013 Bachelor's degree in Information Technology @ FAAP Fundação Armando Alvares Penteado ## Experience Feb 2025 - Present Lead Front-end Engineer @ Ledn Developed a high-performance, responsive frontend for a payroll financing platform; built scalable UI components with Next.js, TypeScript, Tailwind CSS, and Redux; optimized complex financial workflows; collaborated with backend services using Nest.js and AWS; implemented OpenAI integrations.
