Chanaka Bandara
@chanakabandara
Seasoned DevOps and integration engineer focused on cloud reliability.
What I'm looking for
I am a seasoned software developer and DevOps engineer with deep experience in designing, coding, testing and integrating enterprise solutions across cloud and on-prem environments.
I have delivered production-grade Kubernetes platforms (OpenShift, EKS, GKE), built reusable Terraform modules, and implemented CI/CD pipelines with Jenkins, GitLab and ArgoCD to enable zero-downtime deployments and canary rollouts.
My integration experience includes WSO2 APIM/MI/IAM, Kafka integration for at-least-once delivery, ELK-based observability, and HashiCorp Vault for secret management — I have also led disaster recovery design and environment migrations.
I hold CKA and WSO2 certifications and bring a pragmatic, automation-first approach to optimise data flow, reduce operational cost, and improve system reliability.
