Senior Software Engineer / Technical Lead TOTVS
I lead backend architecture for a WMS SaaS platform built with Java and Spring Boot microservices, supporting operations across approximately 5,000 distribution centers and stores. I modernize legacy monoliths into cloud-native services using Clean Architecture, Domain-Driven Design, CQRS, and independently isolated releases.
I delivered AI-driven demand forecasting modules and LLM-based logistics insights, reducing stockouts by 12% and improving demand-planning efficiency by 30%. I built RabbitMQ integrations processing around 500,000 messages daily with zero data loss, implemented Redis caching, and optimized Oracle and PostgreSQL procedures to improve performance.
I established CI/CD and observability practices using Docker, Kubernetes, Terraform, Azure DevOps, ELK, Prometheus, Grafana, and AWS CloudWatch. These initiatives reduced release cycle time by approximately 90%, improved incident detection, and raised automated JUnit test coverage from 0% to about 90%.
I also contribute to Angular and React applications for internal tooling and customer-facing dashboards, helping deliver scalable ERP-WMS integrations for a platform serving roughly 20,000 clients, stores, and distribution centers.
