About
Full Stack Developer with 1.5 years of experience in software development, both in product companies and consulting projects.
I mainly work with React, Node.js and Express, taking part in the full development cycle: feature implementation, API integration, authentication, maintenance and troubleshooting.
My experience has let me work in two different contexts: product — operating on live applications, understanding existing features and shipping incremental improvements; and consulting — adapting to different business needs and delivering results-oriented solutions.
I'm looking to keep growing as a developer, focusing on writing clean code, designing solid APIs and building maintainable and scalable applications.
Core stack: React · Node.js · Express.js · JavaScript · REST APIs · Git · Prisma ORM · PostgreSQL

“ I had the opportunity to mentor Lucas as he grew as a developer and saw his technical progress up close. He stands out for his willingness to learn, ask questions, and understand the why behind solutions, not just close the immediate task. He has a solid base in React and Node.js, and he is also picking up concepts around AI, agents, and new ways of working applied to software development. He is responsible and open to feedback, and eager to keep growing. He clearly has strong potential to keep developing as a professional. ”
