Quarium
An ecosystem of independent IT specialists serving Hungary's universities, ministries, banks, and industry leaders for fifteen years. Methodology-driven engineering for the systems that cannot fail.
Five service lines built on fifteen years of operating Hungary's most demanding systems. Each one is grounded in process, evidenced by the technology stacks we run for our clients in production today.
Solaris and Linux cluster architecture for production web applications and distributed e-learning platforms. Designed to grow with the workload, documented for the people who'll inherit them, built on technology that survives the hype cycle.
Architecture-level performance work — the kind that finds the real bottleneck instead of buying bigger hardware. Database tuning, code review, query plan forensics, and capacity remediation under live production load.
Where IT meets the physical world. Siemens LOGO, Python glue, building automation, industrial gateways, license-plate recognition, IP camera networks — bridges between specialised vendor stacks and the systems that have to read them.
Reddit, Meta, and TikTok paid-acquisition management, analysis, and automation — from server-side conversion APIs to attribution pipelines and campaign optimisation workflows. Where marketing operations meet engineering rigour.
The solution matters more than the technology. Instead of building star destroyers, we deliver projects that can actually be finished.— Quarium founder
Six representative patterns from our portfolio — abstracted away from individual client names, but real engagements running in production today.
Multi-year operational support for a flagship Hungarian university's Linux and Solaris stack. Monthly performance certification cycle, active continuous engagement since 2017 under a public-procurement framework.
Direct takeover and operation of the continuing-professional-development platform used by an entire regulated profession. A/B-instance architecture, Moodle major upgrades, VPN-bridged production access.
Infrastructure operations and development for a multi-year national rural-broadband programme. Government-funded, publicly accountable, delivered end-to-end.
Live response to a 100%-CPU production incident on a tier-1 European insurer's e-learning platform — capacity remediation, MySQL forensics, and a successful TOTARA major-version upgrade carried through to cutover.
English-language architecture consulting for an international aviation-training organisation — cloud-hosted e-learning platform design and review, conducted entirely in English at the architectural level.
Eleven years of hybrid physical-digital IT for a secondary education institution — license-plate recognition at the gate, IP camera intrusion detection, building-automation monitoring, day-to-day systems administration.
People you talk to directly. No account-management layer, no escalation tree — just engineers who own what they ship and inherit what they fix.
Solaris and Linux clusters, distributed e-learning architecture, cross-border consulting in English. Founder.
Linux operations and PostgreSQL — performance, replication, the unglamorous backbone of every web platform we run.
Storage architecture and Linux infrastructure — SAN, replication, the layer where capacity decisions get expensive if you get them wrong.
Moodle, Totara, BigBlueButton — e-learning operations, integrations, and major-version upgrades carried through to cutover.
A selection of organisations whose systems we have planned, built, operated, or rescued — either directly or through long-term partnerships.
Direct line to the people who'll do the work. No account-management layer, no escalation tree, no waiting for someone to read your ticket.
