Binuka is a junior DevOps engineer at Meetrix, working on AWS cloud infrastructure and the products the company publishes on AWS Marketplace. He deploys and tests each product on a clean stack before it ships, and handles the configuration, SSL and DNS work that comes with it.
He also builds the monitoring side of those deployments, putting Grafana dashboards on top of Prometheus so a customer can see what their instance is doing, and works on Jitsi Meet customisation for clients who need the interface to look like their own product.
Documentation is the other half of the role. He writes most of the AWS and GCP developer guides on this blog, covering launching the marketplace image, wiring DNS and SSL, first-run admin setup, where the logs live, upgrades and teardown. He holds a BSc (Hons) in Information Technology from the Sri Lanka Institute of Information Technology.

Yes. Meetrix maintains production images for AWS Marketplace and Google Cloud Marketplace, and the guides published here are written while deploying those products on live infrastructure. Screenshots and command output come from that run rather than from vendor documentation.
Technical claims are checked against our own deployments and reviewed by the engineer who maintains the relevant image before an article goes live. Corrections are applied to the article itself, and the publish date moves with any substantive update.
Email support@meetrix.io with the article URL and your question. If a step no longer works, tell us which one - that is how most of our updates get triggered.
