What I'm looking for

I seek senior backend or cloud roles where I can design scalable microservices, lead migrations to cloud-native architectures, and improve reliability through automation, observability, and strong engineering practices.

I am a senior software engineer with 17+ years building high-performance back-end services, microservices, and cloud-native solutions using Go, Java, and SAP technologies. I design scalable architectures (Hexagonal, Clean Architecture, CQRS), implement event-driven systems with Kafka/RabbitMQ, and deliver robust CI/CD, observability, and DevOps practices on AWS/GCP/Azure.

I have led migrations to microservices, developed SAP integrations and ABAP solutions, and built full-stack applications with Angular/React. My work emphasizes concurrency, reliability, and pragmatic engineering—automating delivery, ensuring observability, and driving business outcomes through resilient, well-tested systems.
