Services

Methodology-driven engineering, top to bottom.

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.

01

IT Systems Planning & Development

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.

02

Performance Tuning

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.

03

Systems Integration

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.

04

Ads Management & Analytics

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.

Featured engagements

What "operating critical systems" looks like.

Six representative patterns from our portfolio — abstracted away from individual client names, but real engagements running in production today.

Higher education·Multi-year

Public-procurement-grade university IT

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.

Continuing education·Regulated profession

National CPD platform takeover

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.

National infrastructure·Public sector

National-scale rural broadband

Infrastructure operations and development for a multi-year national rural-broadband programme. Government-funded, publicly accountable, delivered end-to-end.

Tier-1 insurance·Subcontractor

Production incident triage at scale

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.

Aviation training·International

Cross-border senior consulting

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.

Hybrid campus IT·11 years

Physical-digital campus operations

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.


The team

A small team of senior specialists.

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 & Linux · Clusters

Benedek

Solaris and Linux clusters, distributed e-learning architecture, cross-border consulting in English. Founder.

Linux · PostgreSQL

Zsolt

Linux operations and PostgreSQL — performance, replication, the unglamorous backbone of every web platform we run.

Storage & Linux

Imre

Storage architecture and Linux infrastructure — SAN, replication, the layer where capacity decisions get expensive if you get them wrong.

E-learning

Botond

Moodle, Totara, BigBlueButton — e-learning operations, integrations, and major-version upgrades carried through to cutover.


Clients across sectors

Eleven industries.
Fifteen years of work.

A selection of organisations whose systems we have planned, built, operated, or rescued — either directly or through long-term partnerships.
