GreeceWhat I'm looking for
At KRI KRI S.A., I was part of the team that migrated seven production servers to AWS, and I now handle their day-to-day patching, backups, monitoring, and fixes. I also manage around 250 Microsoft 365 and Entra ID accounts, run Veeam backups, and look after Check Point firewall rules.
As a freelance web developer, I build and host websites for small businesses in Serres, including enablelab.gr. I set up its GitHub Actions pipeline and manage its domains, DNS, and SSL on Cloudflare. I’ve passed the AWS Solutions Architect – Associate exam and am looking for a cloud engineering role in Thessaloniki or remotely.
