At Lojas Colombo, I contributed to the migration of a legacy monolithic system into a modern, modular architecture focused on performance, scalability, and maintainability.

• Migrated front-end codebase from Backbone.js to Next.js with TypeScript
• Used a monorepo to share components and promote code reuse
• Collaborated with backend developers to decouple a monolithic Spring application
• Implemented SEO and performance best practices
• Ensured code quality through unit and E2E tests using Jest and Cypress

I participated in the Crescer program, an intensive internship focused on hands-on experience with real-world projects and solid foundations in modern software development practices.

• Learned and applied OOP, functional programming, and clean code principles
• Built full-stack features with React and Spring Boot
• Followed secure coding and DevOps practices, including CI/CD
• Used Git effectively in collaborative team environments
• Took part in large-scale projects with code reviews and Agile ceremonies
