Background

About Mayara Manso

I’m a Senior Software Engineer focused on building scalable and high-impact digital platforms across fintech, marketplace, and education sectors.Throughout my career at companies like Mercado Livre, Uber, and currently Cielo, I’ve contributed to large-scale products serving millions of users, working across frontend architecture and fullstack development. My core stack includes React, TypeScript, JavaScript, Next.js, Node.js, and GraphQL, operating within microservices and cloud-based environments (AWS).I have strong experience designing scalable frontend architectures, contributing to Design Systems, optimizing transactional and checkout flows, and building data-driven applications. As systems grew in complexity, my role naturally expanded into backend services and API development, ensuring performance, reliability, and long-term maintainability.I value clean architecture, technical ownership, and collaboration in global, cross-functional teams — building not just features, but resilient systems that evolve with the business.
