Building tools around webhosting, domains, and infrastructure. Passionate about self-hosting, automation, and creating useful projects that solve real problems.
I'm a developer with a strong focus on webhosting, domains, and infrastructure. I enjoy building practical tools that automate tasks and solve everyday problems — from network diagnostics to domain monitoring.
Self-hosting is a big part of what I do. I run an extensive homelab spread across multiple sites — Dell Mini PCs, laptops acting as battery-backed servers, and thin clients for remote locations. Everything runs on Proxmox with proper VLAN segmentation and site-to-site tunnels via UniFi.
I believe in learning by building. Some projects stay private (like my domain grabber that monitors availability and auto-registers via NameSilo), while others become public tools. When I'm not tinkering with servers, you'll find me behind a camera or a 3D printer.
Developer & Self-Hoster
Tools I've built for diagnostics, domains, email, and photography
Global network diagnostic platform. Run MTR, ping, traceroute, DNS lookups, and more from 40+ worldwide locations. Real-time results with beautiful visualizations.
Comprehensive IP and domain lookup tool. Get detailed information about any IP address or domain including geolocation, ASN, WHOIS data, and DNS records.
Email deliverability and blacklist testing platform. Check if your mail server is blacklisted, validate SPF/DKIM/DMARC, and ensure your emails reach their destination.
Cristi Scumpu Photography — my portfolio and blog. Capturing moments, landscapes, and aerial perspectives. EU A1/A3 certified drone pilot.
A US-based Rust (game) community focused on PVE gameplay. A passion project from my gaming days that I still maintain and update. No monetization — just for the love of the game.
Personal food delivery tracker that auto-imports orders from Lieferando.at emails. Rate your meals 1-5 stars, add photos and notes. Tracks total expenses and generates price trend statistics over time — the more data, the better the insights.
Photography companion tool that downmixes images and adds a stylish info bar with EXIF data — camera model, lens, aperture, ISO, shutter speed, GPS location, and custom watermark. Built for my Sony A7C II workflow.
Self-hosted AI assistants powered by local LLMs
Chat with my AI assistant about networking, open source, self-hosting, photography, and homelabs. Powered by Ollama running locally on my infrastructure with load balancing across multiple hosts.
Specialized AI for correcting English and German grammar, spelling, and punctuation. Perfect for customer support tickets in telecom and webhosting. Preserves technical accuracy and original meaning.
