Gláuber Costa

I’m a Senior Backend Engineer with 13+ years building and modernizing financial systems, currently focused on cloud-native backend platforms, distributed workflows, and legacy modernization at Itaú Unibanco. I act as a hands-on technical reference—leading solution design, architecture decisions, and implementation as a senior individual contributor, with a strong product-driven delivery mindset.

I design AWS-based architectures that separate synchronous and asynchronous responsibilities, model data access patterns, and propagate business context end-to-end across HTTP calls, Lambda payloads, SQS messages, and Kafka events. Most recently, I led EasyMin’s modernization from a 20-year legacy platform—using Java 21 microservices, AWS Lambda, SQS FIFO, Kafka, DynamoDB, S3, and ECS/EKS—while improving resilience with Resilience4j and traceability with Datadog observability. I also bring AI-augmented development into my workflow, including GitHub Copilot/Copilot Agent, and I’m actively evaluating Devin AI for autonomous development.
