I designed and developed critical modules (payroll, routing, traceability) using Java 17, Spring Boot 3, NestJS, Python (Django DRF), PostgreSQL, and AWS. CI/CD deployment with GitHub Actions. Multi-tenant architecture in Latin America.

I led the migration of a TMS/WMS logistics system from a monolith to cloud-native microservices. I implemented route optimization and anomaly detection using Python, AI, and PostgreSQL, achieving 30% savings and 70% efficiency.

I developed critical banking microservices (transfers, funds) using Java, Spring Boot, PostgreSQL, Docker, GitLab CI/CD, Terraform, and AWS. I implemented idempotent controllers, concurrency, and automated QA.

I designed 12+ microservices using Java 17, Spring Boot 3, PostgreSQL, and GraphQL. I introduced generative AI for testing/documentation, optimized policy systems (+25% throughput), and led technical teams.

I implemented backend logic, advanced debugging, and SQL queries in PostgreSQL. I participated in the design of scalable infrastructure using the AWS Well-Architected Framework.

I developed REST APIs using Python 3.11, Django DRF, and PostgreSQL. I collaborated on Dockerized deployments, AWS Lambda, and Step Functions. I documented endpoints with Swagger and improved traceability.
