About

Professional summary

I am a software engineer with over 10 years of experience, with a strong emphasis on front-end development and building scalable web applications.

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.
