    Hey, I'm Victor Mannelli 👋

    A Full Stack Software Engineer from Brazil

    I have 4 years of experience building scalable web applications, real-time systems, and cloud-deployed products. I work primarily with TypeScript, React, Next.js, Node.js, and PostgreSQL, building full-stack platforms from architecture to deployment.

    Most of my experience comes from working in small, high-ownership engineering teams, where I contributed across the entire development lifecycle — designing frontend architectures, building backend APIs, integrating external systems, and deploying production infrastructure.

    I’ve worked on products ranging from real-time betting platforms serving tens of thousands of users to health-tech systems that process and automate clinical workflows using AI pipelines.

    I enjoy building end-to-end systems, solving architectural challenges, and turning complex ideas into reliable, production-ready software.
