Tehlo — Systems Administrator
Ten years of production infrastructure. Day to day that means Proxmox hypervisors and Docker containers, Nginx doing HTTP and stream proxying, Fabric Minecraft servers tuned for real player counts, and a Prometheus/Grafana stack wired into all of it. In 2019 I started DedicatedMC, a game hosting provider, with two friends — I ran the marketing and the infrastructure — and we sold it in 2022.
Linux from bare metal up. Proxmox hypervisors, Docker containers, networking and firewalling, TLS termination and reverse proxying, user and access management, and scheduled backups with restores that actually get tested.
Fabric servers with JVM and GC tuning for the player counts they actually see, sitting behind Nginx stream proxies for routing and isolation. Modpack pipelines and version syncing, Java/Bedrock cross-play, and automated world backups.
Prometheus and Grafana across every host, with Pushgateway for the things that can't be scraped, per-server labelling, and alerting on the metrics that actually predict failure. Plus the APIs, scrapers and internal tools on top — mostly Node and Python.
DedicatedMC was a game hosting provider I started in 2019 with two friends and sold in 2022. I ran marketing and everything on the systems side — the hardware, the provisioning, the monitoring, and keeping the infrastructure alive.
It's where most of what I know about running services other people depend on came from: what breaks, when, and what it costs to find out late.
Sysadmin and infrastructure, plus all of the marketing. The two ends of the business that decide whether anyone shows up and whether anything stays up.
Started the company with two friends, sourced the hardware, and built the hosting stack from scratch.
Automated instance provisioning, node orchestration, billing integration, and per-instance monitoring.
Added capacity, hardened the network against abuse and attack traffic, and brought customers in through the marketing side.
Handed over a running business with documented infrastructure and an operational playbook.
A vanilla Minecraft community running Java and Bedrock cross-play, on infrastructure I designed, tuned and monitor.
A web tool that reconciles a player's installed mods against the live server modpack, so support stops being guesswork.
A public stats and leaderboard site fed by scrapers and an API that turn raw world data into player-facing awards and advancement tracking.
Prometheus, Pushgateway and Grafana wired into every server, with per-server labelling, dashboards, and alerts on the metrics that predict failure.
Proxy management, paste and file services, dashboards, galleries and timelapse pipelines — self-hosted, TLS-terminated and backed up.
