What I'm looking for

I'm looking to build and evolve Java backend services and microservices, contributing from requirements and architecture through production deployment, observability, and reliable delivery.

I build Java and Spring Boot services for banking platforms, most recently supporting Citi’s cards environment at Tata Consultancy Services.

I design REST APIs and microservices from scratch, including customer-data and card capabilities, dynamic-boleto registration, DynamoDB persistence, and asynchronous Kafka/RabbitMQ flows. I also work with AWS EKS, EC2, S3, API Gateway, Secrets Manager, Redis, CI/CD, Grafana, and OpenTelemetry.

At T.O. Brasil, I delivered more than 10 microservices for Santander, including purchase-dispute and customer protocol features supporting up to 50,000 operations per day. I took services through data modeling, automated testing, homologation, production rollout, and initial transaction verification, achieving over 85% unit-test coverage for protocol generation.

Earlier, I developed Java IVR and backend solutions for Banco Safra and telecommunications environments using Cisco CVP and Genesys GVP. I bring 10+ years of development experience, grounded in Java, clean architecture, relational databases, and production-focused delivery.
