Fix server crashes, downtime and performance issues – fast.
When your infrastructure breaks at 3am, I get it back online - like when I restored a 3,000-player cluster in under 15 minutes, before player loss escalated into churn and revenue drop.

I step in when servers crash, data is at risk, or performance kills your users - and fix it without downtime or guesswork.

I fix broken servers, debug Nginx and Apache, manage game hosting, and set up Discord communities - so you don't lose users, revenue or sleep over infrastructure.

Better option: Hetzner or OVH for managed hosting at scale; regional IT firms for on-site work.
Still a fit? Let's talk about your project.
Linux sysadmin since 2015, firefighter at the Ministry of Defence SR since 2016, and author of AiSeoModule - a PrestaShop AI SEO module. Based in Košice, Slovakia.
I build and maintain Linux servers, game server infrastructure, and web platforms - from Proxmox virtualisation to custom PHP apps. Outside of IT, I respond to emergencies as a professional firefighter. I also develop plugins for Hytale and Minecraft, and run 7 gaming community websites across Slovakia and the EU.
When your server goes down, you lose users, revenue, and trust. I fix it fast - and make sure it doesn't happen again. Here's what I do.

| Game Server Hosting | Pterodactyl, Minecraft, Hytale | 1–10 game instances | AAA game publisher infrastructure |

| AI SEO Consulting | AiSeoModule, JSON-LD, llms.txt | PrestaShop & PHP projects | Magento / Shopify ecosystems |
When your server goes down, you lose users, revenue, and trust - I fix it fast and make sure it doesn't happen again.

Real situations. What broke, how I fixed it, what changed.
3,000+ active players. Cluster failing under peak load. Every minute down = lost players and reputation.
Problem: Resource exhaustion cascading across nodes. Players getting kicked, data at risk.
Fix: Isolated failing node, redistributed load, restarted services in correct sequence.
Result: From cluster failure → fully online in under 15 minutes. Zero data loss. No repeat incident.
E-commerce site crashing every 12–18 hours. Client losing ~€2,000/day in sales. Previous provider couldn't find the cause.
Problem: Recurring crash every 12–18 hours, client losing business. Previous provider couldn't diagnose it.
Fix: Traced to a misconfigured OPcache interaction. Pool config rewritten, monitoring added.
Result: From crashes every 12–18 hours → zero crashes for 6+ months. ~€2k/day revenue recovered. Client on retainer since.
40,000+ login attempts/hour across 3 servers. One successful breach = all client data at risk.
Problem: 40,000+ login attempts per hour. Existing Fail2Ban config not catching distributed IPs.
Fix: Hardened SSH config, deployed geofencing, tuned Fail2Ban rules, rotated credentials.
Result: From 40k attempts/hour → zero successful logins. Attack neutralised in 2 hours. No breach since.
