I am Zacharias (Aris) Tzermias and I live in Heraklion, Greece.
Currently, I am a Lead Platform Engineer at Camelot Lottery Solutions, focusing on creating scalable infrastructure for lottery applications as well as improving deployment pipelines to ensure smooth and robust application deployment from development to production. Towards this end, I regularly troubleshoot and develop Terraform modules, Ansible playbooks and Kubernetes Helm charts among others.
Previously, I was a Site Reliability Engineer at Oracle Cloud, focusing on providing logging and metrics services at scale for a diverse set of customers. Supporting Elasticsearch and Kafka clusters for logging and large Graphite and Prometheus installations were my key responsibilities. Prior joining Oracle, I was a System Administrator at Top.Host, one of the largest web hosting providers in Greece, located in Heraklion, Crete. My main responsibilities were the maintenance and monitoring of shared webhosting infrastructure. I also provided high quality technical support to end customers.
I have also worked in academia, as an R&D Engineer at Distributed Computer Systems Lab (DCS) of FORTH-ICS. My main research interests included privacy leakage, social network forensics and I also participated in the EU-Funded projects ForToo, i-Code, MOMENT and TRACER.
In my spare time, I enjoy tinkering with electronics projects and retrocomputers. I occasionally code for some of my personal projects (you can find them on my GitHub profile) as well as enriching my knowledge on System Administration, Computer and Network Security and Linux in general. I am also a licensed Amateur Radio Operation in Greece (since 2020), under the callsigns SV1SOL (inactive) and SV9SOL. I used to photograph in the past, as you can see from the background page of the site. A few more snaps are available on my 500px profile.
