Discover how microlearning helps overworked DevOps engineers beat burnout, conquer tool sprawl, and continuously upskill in just 5 minutes a day.
Indika is a Lead DevOps Engineer and technical writer dedicated to bridging the gap between complex cloud infrastructure and accessible DevOps education. As the creator of CloudQubes, he helps both fresh graduates and seasoned engineers navigate the fast-moving world of cloud certifications, CICD, and automation.
With a deep specialization in AWS architecture and Infrastructure as Code, Indika brings years of hands-on production experience to his teaching. He is an instructor for AWS Cloud Practitioner certification courses and the author of A Guide to Cloud Certifications for Aspiring DevOps Engineers.
His technical philosophy centers on building robust, scalable systems using the right tools for the job—whether that means managing infrastructure with Terraform, OpenTofu, automating with Ansible, running rootless containers with Podman, or developing modern web applications with Ruby on Rails 8.
Beyond writing tutorials and mentoring, Indika is an active open-source contributor, having developed Ruby gems like prometheus_graph, ms_graph_lite, alongside Python applications for automated network fault detection.

Beyond the Terminal
When I'm not architecting cloud environments, I spend most of my time backyard farming. I also enjoy tinkering with bicycles and cycling local gravel paths. When I'm not out in the field, you can find me building circuits and working on robotics projects.
