Devops & SRE

Started my IT career as a Technical Support at an Indonesian web hosting provider, then progressed through various roles as a Linux SysAdmin, Network Engineer, Product Designer, and DevOps Engineer. I moved to a SaaS company and since then I’ve built hands-on experience mainly with AWS and GCP and work daily with popular cloud native tools.
