Matheus has been a full-stack software engineer since 2014, now specializing in front-end development using React. With a focus on clean code, clean architecture, and TDD, he has excelled as a freelance engineer and as a direct-hire technical project manager, tech lead, and full-stack developer. Curious by nature and consistently trying to figure out how things work, Matheus started teaching himself to program at age 11 and never stopped.
