Eelviny.

Hi, I am Eelviny.

My name's Elvin Luff, but I go by the username Eelviny. I'm an AWS Cloud Architect by day, smart home tinkerer by night, with a passion for all things running and IoT. Welcome to my space.

I spend my 40 hours as a Cloud Consultant for Xebia, helping organizations across all industries kick-start their next project in Amazon Web Services. Whether your project is the next AI sensation, a high-throughput event-driven system or just a simple internal HR app, it needs a systems architect with an eye for security and an automation-first approach. That's me.

What I'm working on.

How to replace a UPS battery, the hard way

31 Oct 2025

My homelab needs are pretty simple. Sitting in the closet by the front door, just below the energy meter, is what I call the Vault. A single tower PC on a shelf, that runs my entire smarthome. I designed it as an everything in one device - it pulls duty as a NAS, OPNsense router, Jellyfin server and Home Assistant hub, among other things. Single point of failure? Absolutely, which is why I’ve got a UPS to protect it.

Where to find me.
