About me
I’m a software engineer at heart, driven by an open-minded and innovative approach to problem-solving. My daily mission revolves around architecting comprehensive, cloud-native software solutions, from robust C# and Python backends (with a dash of Go and TypeScript) to streamlined DevOps pipelines and automation.
I bring deep expertise in Kubernetes and containerization to deliver highly scalable and resilient applications across platforms like GCP and AWS. Furthermore, I've successfully implemented advanced observability solutions in previous roles, designing with Grafana and Elastic, powered by OpenTelemetry, to ensure full operational insight.
