Summary
Carlos Castro is a Senior Software Developer based in São Paulo with about six years of experience building full-stack web and mobile platforms using React, Next.js, NestJS and AWS. He has been a founding developer at a fast-growing startup where he delivered a multi-tenant condo management product to 50+ clients and helped the company reach financial break-even. Carlos routinely ships end-to-end features—from real-time chat and social auth to in-app payments and infrastructure automation—and has a track record of fixing long-standing legacy issues and optimizing database designs. He’s worked on impact-driven projects, including a housing-regularization platform that accelerated services for over 10,000 families. A lifelong gamer turned engineer, he brings an early curiosity about interactivity to UI and mobile experiences and enjoys solving practical layout and front-end challenges (as his Github quip “How do I center this div?” playfully hints). Currently focused on React + Node, he pairs hands-on coding with AWS-centered deployment patterns and pragmatic product sensibilities.
