Vinicius dos Santos Oliveira

I am a Full Stack Developer experienced in building scalable web applications and secure RESTful APIs using React, TypeScript, Node.js, Express, PostgreSQL, and Prisma. My portfolio includes a financial REST API featuring JWT authentication, RBAC, and request sanitization, as well as web applications where I optimized performance, reducing payload size by 58%. I consistently apply Clean Architecture, SOLID principles, and automated testing (Jest, Cypress) to ensure software reliability. Currently pursuing a degree in Systems Analysis and Development at UCB, I am actively expanding my knowledge in backend engineering, AWS cloud computing, Python, and system design.
