Competence areas
Governance & leadership
IT strategy, operating models, building and leading IT organisations, reporting lines up to executive management.
Risk & compliance
Information security as a risk discipline: access control, incident analysis, data-protection and export-compliance practice.
IT/OT security
Separation and interplay of IT and control systems in production environments; security and backup architecture from day one.
Infrastructure & operations
Windows Server, virtualisation, Citrix/VDI, networks, migrations - built from scratch or modernised in place, always operable.
Vendor steering & procurement
Tenders, TCO evaluation, negotiation, acceptance and the transition from contractors to internal teams.
Transformation & products
Digital products with full ownership: web platforms, native clients, subscription operations - architecture to support.
§ 03
Selected work
GroupDF International, Vienna - IT & security across 7+ countries
Situation: fragmented IT landscape across several countries, geopolitically unstable environment, strict regulatory and export-compliance requirements.
Approach: unified infrastructure and security strategy, reorganisation with zero downtime, consistent vendor governance, secured communications for the leadership level.
Result: uninterrupted operations through several crisis years; consolidation of the telephony and communications landscape; governance that holds up in front of auditors and partners.
Oil & gas project (international) - IT operating model and IT/OT separation
Situation: multi-site project (city office, engineering base, production sites) without a defined IT organisation, operated by external contractors.
Approach: design of the IT operating model, clear separation of IT vs. OT/control-systems responsibility, definition of the specialist structure, plan for the transition from contractors to an internal team.
Result: a sustainable operating model with defined interfaces to international technology partners; security and backup architecture planned in from the start.
Austrian energy company - secure remote workspace
Situation: outdated local infrastructure, distributed team, no internal IT.
Approach: hardened Windows Server domain with remote desktops and file services on European cloud infrastructure, controlled data migration, corporate telephony and company website.
Result: stable, documented operations - delivery, documentation and accountability from a single source.
MIPT research centre - infrastructure from six desks to a campus
Situation: start-up phase of a research organisation: six employees, one office, no infrastructure.
Approach: built virtualisation, private cloud, compute clusters and a helpdesk; IT planning for a new R&D facility; growing the IT function alongside the organisation - from IT manager to CIO.
Result: uninterrupted research operations through years of growth and several relocations.
Retail network (AT + CZ) - management platform for 22 stores
Situation: a growing store network with POS, warehouse, logistics and staff processes and no unified system.
Approach: concept and full-stack delivery of one platform: point of sale, warehouse with scanning, logistics, HR and role-based dashboards for management and accounting.
Result: a working end-to-end system across all roles - proof that concept, delivery and operations can come from a single source.
Own product - zero-trust remote-access platform
Situation: the need for trustworthy, secured remote access with the standards of a commercial service - not a hobby project.
Approach: as a founder: distributed European server infrastructure, own Android and Windows clients, subscription management, monitoring and support - product ownership from architecture to operations.
Result: a live service with real users; P&L, product and operational responsibility in one person.

§ 04
Further projects & products
Further work - hands-on delivery from concept to operations.
Infrastructure renewal, trading company
Replaced two hypervisor hosts with a single Dell R640, migrated the domain including directory services and terminal server, deployed SQL Server 2025 for the ERP - without interrupting operations.
Personal AI assistant
Own tool: Telegram bot with speech recognition on a local GPU, connected to mail and calendar, automatic sorting of incoming mail.
Backup with restore testing
Automated backup in PowerShell that does not just copy but regularly verifies the restore - a backup only counts once it can be restored.
IP telephony for an Austrian company
Self-hosted PBX on a dedicated server, Austrian phone number, calls from the app and straight from the browser (WebRTC); optional transcription and call summaries.
Digital health twin (MVP)
Web platform: training, nutrition and sleep data drive a digital twin - tracking, sober projections, progress compared over time.
Architecture graph of a codebase
Interactive graph built straight from source: 2,441 nodes, 197 clusters, function and database relationships - a tool for reviews, handovers and onboarding.
§ 05
Governance & trust
Regulatory focus
Security as a governance duty: access and vendor control, incident analysis, reporting lines to leadership - lived practice in international environments with data-protection and export-compliance requirements. Not a list of tools, but accountability.
Legal background
Legal education complementing the technical career: contracts, liability, compliance and vendor control are handled with a legal eye - a working advantage in regulated environments.
Verifiability
Raised in Austria, based in Vienna; German as a native language. References on request; ready for background screening. Work strictly within the legal framework.
Way of working
The real problem first. Build systems that stay operable. Total cost, not purchase price. Verify results personally - responsibility does not end with the presentation.
