Support first. Security next.

My foundation is practical IT support. I'm now adding formal cyber security study and deeper systems work to it.

Operating the thing matters.

Writing code is only half the job. My homelab work focuses on keeping services reachable, recoverable and understandable when something goes wrong.

FLAGSHIP PROJECT

Lelle Nyaralás

A multilingual holiday-rental site turned into an operational booking workflow for two apartments in Balatonlelle, Hungary.

I designed the customer-facing journey and took the wider workflow through implementation, including live availability, save-first enquiries, notifications, an admin dashboard and conflict-aware calendar approval.
