About
Platform Engineer / SRE with hands-on experience running production Kubernetes environments for enterprise clients across financial services, insurance and banking.
I operate and support production Kubernetes platforms across multiple clients, build monitoring and alerting stacks (Prometheus, Alertmanager, Grafana, Elasticsearch/Fluentd), and deploy and maintain API and integration middleware including IBM App Connect Enterprise, IBM API Connect and WSO2. I have also built OpenShift pre-production environments. Working with many clients has sharpened my fault-finding and incident-resolution skills.
Certified Kubernetes Administrator (CKA). Always keen to keep learning and add value.
