About
I’m Mariane, a Brazil-based Front-End/Full-Stack Developer with 5 years of experience specializing in React.js and TypeScript. I’m known for taking initiative and providing technical leadership, focusing on building scalable and reliable applications. I actively contribute to planning features and refactors, anticipating dependencies and impacts on existing systems, and supporting back-end teams in shaping workflows and defining routes to meet business needs.
My edge lies in delivering high-performance, high-quality code with measurable impact. I led a modernization of a legacy project, removing obsolete libraries and optimizing the stack, resulting in a dramatic 75% reduction in build time. I value performance and clean architecture, and I collaborate closely with UX/UI teams to maintain cohesive UI standards while driving continuous improvement.
