What I'm looking for

I'm looking for remote backend opportunities where I can build scalable Java and AWS systems, lead technical decisions, solve integration challenges, and collaborate directly with clients and distributed teams.

At SulAmérica, I build and maintain Java Spring Boot services handling 50k+ daily requests and helped migrate critical modules to a scalable microservices architecture. I led a SOAP-to-REST middleware initiative that opened new integration-based business lines and enabled millions in additional billing.

At PalmSoft Tecnologia, I lead six engineers while setting architecture and technical direction for backend services on AWS. I work directly with clients to turn business requirements into scalable software, and improve delivery through mentoring, code reviews, CI/CD, and Docker deployment practices.

I've built REST APIs, event-driven integrations, and distributed systems using Java, Spring Boot, SQL, MongoDB, and DynamoDB. I also contribute with React when needed and am available worldwide as a remote independent contractor.

As Technical Lead, I guided 6 engineers on architecture, delivery, and technical direction, building full-stack apps end-to-end (Java/Spring Boot backend, Angular/TypeScript frontend) with microservices, REST APIs, and NoSQL (MongoDB, DynamoDB). I aligned architecture with business goals, mentored via code reviews, and drove CI/CD, Docker, and AWS deployments using GitLab Boards in agile teams.
