Servers, backups and security
Rust, network traffic analysis and server administration. Things that must keep running when nobody is watching.
I deploy your site or app to a server and set up backups, updates and monitoring. My bachelor’s thesis was on passive network traffic analysis: my Rust tool finds known vulnerabilities for the services on a network and ranks what to fix first.
I work as a freelance software engineer from Nové Město nad Metují, Czechia, for clients in Hradec Králové, Náchod and the whole region. Remotely I work with anyone, in Czech or English.

What I will do for you
- 01
Deployment without surprises
Docker, Linux and VPS. Every change passes tests before it goes live.
- 02
Backups that actually work
Daily off-site backups and recovery tested for real. A corrupted backup is rejected before it can overwrite anything.
- 03
Monitoring and updates
Automatic security monitoring, broken-link checks and scheduled jobs nobody has to remember.
- 04
Network analysis
Service inventory, known vulnerabilities (CVE, EPSS, KEV) and Zeek and Suricata traffic, ranked by what to fix first.
Work examples
Website and CMS · 2026zskom.cz The school wanted a website it could run on its own. I built all of it, from the design and a custom content system to the server it runs on. Articles go to Facebook and Instagram in one click.
Bachelor’s thesis · security · 2026Passive Traffic Analysis A list of open ports is not enough. My Rust tool finds known vulnerabilities for them and links them to what is actually happening on the network.
Questions
- Will you look after the site after launch?
- I can. Backups, updates and monitoring are set up at launch and I can keep managing them.
- Can you check a network’s security?
- I can map the services on a network and find known vulnerabilities for them. I only scan networks I am authorised to scan.
- How quickly will you reply?
- Within two working days. Tell me what you need and I will suggest the next steps.
