Hiruna is the senior DevOps engineer at Meetrix, responsible for the infrastructure customers actually run on. He builds and maintains the AWS Marketplace AMIs and Google Cloud images the company ships, packages new open source products for both marketplaces, and keeps that catalogue patched, reproducible and working after each upstream release.
A good part of his week is customer engineering rather than product work. He handles large-scale Jitsi Meet deployments, on AWS and Google Cloud as much as on-premise, which means scaling videobridges, sizing the media path and keeping the thing stable once real load arrives. On-premise brings its own constraints on top: firewalled networks, restricted systems, hardened Linux hosts and security review, with the Docker setup, the TLS and reverse proxy layer and the identity integration all on his side.
He is an AI enthusiast, and what he actually does with it is build tooling. Using Claude Code and similar, he has automated the repetitive end of getting a product to market: packaging it, shipping it and publishing the listing to the AWS and Google Cloud marketplaces, work that used to be done by hand every single time.
He studied Computer Science at the University of Moratuwa. The deployment guides he writes here come out of the same infrastructure work.
