What I'm looking for

I’m looking for a backend/microservices role where I can design scalable architectures, build AWS-based systems, and own production reliability through monitoring and troubleshooting—working with a team that values clean engineering and dependable releases.

I’m a Senior Software Developer with 12+ years building backend systems and microservices for banking, payments, and large-scale retail. I focus on Kotlin/Java and AWS to deliver reliable, production-ready services.

I’m especially strong in scalable architecture (Hexagonal, CQRS) and operational excellence—monitoring, troubleshooting, and reliability. In recent roles, I built and maintained Kotlin+Spring Boot microservices for banking workflows (Itaú) using AWS+Docker, WireMock testing, and Datadog for stable releases.

Across my experience, I’ve modernized and integrated complex systems—supporting SAP integration, building PIX and chatbot integrations, and running ordering microservices with Apache NiFi. I also maintain high-throughput POS platforms used in 1,000+ stores, integrating AWS messaging/storage (SQS/SNS/S3), monitoring with CloudWatch/Datadog, and building serverless functions (AWS Lambda) in Go and other stacks.
