Hey, I'm Daniel, a dev by passion from near Frankfurt am Main, a hosting nerd and AI tinkerer, and currently in my second year of training as an IT specialist for system integration. I live for technology, IT infrastructure and artificial intelligence, and learning by doing is my thing because I'd rather build servers than slide decks. That AI tinkering includes ai-chat-webui, a privacy-focused chat UI for local Ollama models: https://github.com/drosemann/ai-chat-webui I've been active in the Minecraft and hosting community for years, and since 22 April 2018 I've been running my Minecraft server ShadowUnity. For my own projects I use my private stack, while at work I use the stack required there. My full stack work covers HTML, CSS, JavaScript, Java, PHP, Python and React and TUI development. My infrastructure work covers Docker, Linux, NGINX, Apache, Proxmox, Velocity and KVM with libvirt. I have a lot of experience with the Pterodactyl and Coolify panels, but for my own services I now prefer pure Docker because it means less overhead and more control. I have a lot of productive experience with MariaDB and I've tested Supabase extensively, both in the cloud and self hosted. I use Cloudflare for DNS, HetrixTools for monitoring, Trello and Notion for project management for ShadowUnity, and Vercel for automatic deployments. My browser survival game stranded-horizons is the one project still on Vercel auto-deploys: https://github.com/drosemann/stranded-horizons On the client side I use Windows, with a nod to the games industry, and I plan to switch to Linux as soon as anticheat support gets better. My focus is on cybersecurity, AI, cloud and virtualization, and automation with Python. For that Python side I built aktienwerk, which turns SEC filings and stock prices for 100 US companies into plain explanations with only the standard library and SQLite: https://github.com/drosemann/aktienwerk My hosting path went from Aternos to Ploudos to Minehub, which later closed. After that it went through DeinServerHost, Strato, Host-Unlimited, LuxVPS and Mine-Hoster. I cancelled ST-Hosting after one month because their LXC setup didn't meet my expectations, and HT-Hosting went insolvent, which taught me to migrate under time pressure. I used Index Hosting until mid March and cancelled it because their AMD EPYC range was discontinued. In between I tested Vercel and Kinsta, which had the best developer experience with edge and CDN, but self hosting is cheaper in the long run. At times I ran three or four servers in parallel as development, failover and main systems. Before my training I did three helpdesk internships, two school internships and one voluntary one, all unpaid and all just because I enjoyed the work. I produced over 2,000 YouTube videos and streamed live for hundreds of hours, which taught me community building, live technology, video production, consistency and dealing with feedback. ShadowUnity runs at play.shadowunity.de and hasn't had a reset since 2022. Its plot system is streuland, my Paper plugin for protected vanilla-style plots instead of a standard grid: https://github.com/drosemann/streuland Its name history is GrieferPrinz from the Pocket Edition days, inspired by GrieferKing and GrieferGames, then MelonenGames as my first Java server with only CityBuild, then DiamantSucht because that was my in game name, then DanielArmy during a personal brand phase, then MineRush, inspired by MineSucht by Abge and FloTastisch, and finally ShadowUnity, from ShadowFox plus community, which has been stable ever since. From 24 January 2025 to 26 April 2025 I ran the DMH Network together with Matti and Henry. Under my old alias MineHub I published SpigotMC plugins at https://www.spigotmc.org/resources/authors/minehub.1035036/ Since 10 September 2023 I've been part of Emergency Response: Crestwood County, a Roblox roleplay project. I also built a Raspberry Pi AI plant monitoring project with sensors and AI, and I spend time on hardware hacking and AI security. I also built cooperating-screen for cross-device screen sharing with Flutter, WebRTC and a Node.js signaling service: https://github.com/drosemann/cooperating-screen After over 2,000 gaming videos I made 15 videos in the Theo Browne style, archived at https://github.com/drosemann/drosemann/tree/main/theo-browne-era-video-style All of my domains are with netcup: d5niel.de for my portfolio, which will run on ForgeCMS (https://github.com/drosemann/forgecms) in the future, shadowunity.de for my Minecraft server, and hosting-club.de, a former hosting forum. For writing itself I use ed-docs, an offline-first Markdown workspace with ed/vi habits like i, a, Esc and :w: https://github.com/drosemann/ed-docs Over the years every hosting era also produced a forum or blog attempt, ten in total, and I finally merged all of them into one codebase: forum-for-nerds (https://github.com/drosemann/forum-for-nerds), a self-hosted Next.js forum plus blog running on pure Docker with SQLite for dev and MariaDB in prod. Ten dead forums walked in, one nerd forum walked out. For storage I ended up with OneDrive 365 Basic with 100 GB for 2 euros a month, after years of being convinced I'd never give Microsoft a cent, until the Windows and Samsung integration won me over. Speed doesn't matter much to me, and if OneDrive ever offers a 500 GB cold archive tier on very slow old hard drives for one or two euros a month, I'd be the first customer, and I'd probably store all my photos there too since 100 GB is easily enough for me. I never actually needed it, since I never used more than two or three GB, but now I just upload 30 GB so I can say I use it. The stupid thing is I always said "no SaaS subscriptions", then October 2026 came and I ended up with two: OneDrive 100 GB and Muse Code for 4,29 €/mo. Back in April 2026 I predicted — and tagged Meta — that they should ship a $5/month tier with a lot of tokens: https://x.com/d5_iel/status/2113593415564771351 — and they actually did. Honest take though: I would have subscribed to whichever lab shipped a ~$5 tier first. Muse Code itself is surprisingly good: it's terminal-only and the UX is a bit bad, but it has really useful features and the syntax highlighting is genuinely nice, and the Everyday tier is enough for a ton of work. I did have to add some strict personal memory settings to not burn a ton of tokens: single session only — never use subagents, observers or multiple sessions, verify everything myself in the main thread; save tokens, be concise, avoid parallel exploration; stop after 1–2 failed attempts on the same task and escalate with what was tried, the exact blocking error and what's needed instead of retrying variants, treating repeated tool failures, permission denials or unchanged output as a hard stop; and default to writing code/files only — never run, test, verify, execute, install or set up environments (no Python/Node/NPM installs, no builds, no test runs, no servers) unless I give explicit approval first. Long term I don't want just any job, I want to build my own thing and found an IT company for hosting, infrastructure and IT consulting, based on infra-pilot (https://github.com/drosemann/infra-pilot). I want scalable cloud solutions instead of generic root servers, built on pure Docker and KVM. I also want to buy an old house, make it smart the cheap way, and document all of it on YouTube. I want to share what I learn, so a YouTube channel about IT and hosting is planned. I'm open to collaborations in IT, AI, hosting, gaming and software development, so if you want to build something real, feel free to reach out. You can reach me at daniel.rosemann10@gmail.com.
