About me
Technology, organization, and solutions built to evolve.
I am a Full Stack Developer with a technical background in Information Technology, currently pursuing a degree in Systems Analysis and Development at UNASP.
My experience includes system development, support, testing, documentation, databases, and digital tools. I also have experience with customer service, document organization, information control, schedules, and spreadsheets, in addition to a 200-hour supervised IT internship.
I bring an analytical, organized, communicative, and adaptable profile, with fast learning and a focus on functional solutions, process improvement, and collaboration.
Main projects
Products and solutions applied to real needs.
ImunoLink
Digital platform for vaccine and health-profile management.
Built by a two-person team. My teammate focused on the front-end, while I was primarily responsible for the back-end: business rules, database structure, integrations, validations, and information security. I also contributed to front-end stages, taking on a full stack role at key moments of the project.
