What I'm looking for

I’m looking to build scalable, multi-tenant SaaS systems with microservices, clean architecture, and strong developer experience—owning APIs, front-end, and performance. I want a team where mentorship and code quality are valued.

I’m a hands-on Software Architect and Software Engineer with 5+ years of experience, progressing from Junior Developer to Architect within the same company. I’ve led the architecture of an educational SaaS platform used by major Brazilian institutions.

I launched a scalable multi-tenant platform as Software Engineer & Software Architect, optimizing critical queries from ~10s to ~999ms. I also built internal component libraries and a Design System from scratch to improve consistency and delivery speed.

I lead microservices and modular monolith architecture using NestJS, Clean Architecture, DDD, and SOLID principles. On the product side, I ran POCs that became new sold products, and I built scalable RESTful APIs with JWT/OAuth, Prisma ORM, and PostgreSQL/MySQL/MongoDB.

I mentor developers, perform code reviews, and have been a technical lead for a 3-person squad delivering systems for one of SP’s largest educational institutions. I enjoy working end-to-end—React.js, TypeScript, Redux/Zustand, React Query, and modern DevOps practices like Docker and CI/CD.
