I build high-availability Go microservices and cloud-native platforms serving millions of users.

At NORA Digital, I architect cloud-native Go microservices on Kubernetes supporting over 1M users with 99.9% uptime. I improved API response times by 68%, accelerated deployments from three hours to 20 minutes, and strengthened observability with Prometheus and Grafana.

Previously at MySEK, I built Go and PostgreSQL REST APIs handling 500K+ daily requests at 99.95% uptime, reduced latency by 72%, and automated infrastructure provisioning with Terraform. I enjoy building scalable, secure distributed systems with practical automation and performance in mind.
