How I Work

I help organizations navigate complex technology challenges, where strategy, architecture, and execution intersect and conventional boundaries don't apply.

Service Areas

Strategic Advisory

Board-level guidance on technology strategy, transformation programs, and complex business-technology decisions. Bringing executive experience to challenges that require both strategic vision and technical depth.

  • Technology strategy and multi-year roadmaps
  • Digital transformation program design
  • M&A due diligence (buyer and seller side)
  • Security strategy aligned to business objectives
  • AI strategy and readiness assessment
  • Organizational transformation and restructuring

Architecture & Design

Hands-on architecture work for complex systems. Not just diagrams and documents, practical designs informed by implementation experience and operational reality.

  • Enterprise architecture
  • Security architecture
  • Threat modeling workshops & capability building
  • Cloud-native system design
  • AI/ML system architecture and integration design
  • Architecture reviews and due diligence

Technology Leadership

Embedded leadership for organizations navigating transitions, building capabilities, or filling critical gaps. From program delivery to team building.

  • Interim/fractional technology executive roles
  • Transformation program leadership
  • Team building and organizational design
  • Vendor evaluation and selection
  • Technology capability development

Technical Depth

Current, hands-on experience across these domains, not historical knowledge, but active capability I apply to client work.

Security

  • Enterprise security architecture
  • Threat modeling (STRIDE, MITRE ATT&CK)
  • Zero Trust design and implementation
  • Security operations (SIEM, SOAR)
  • Governance, risk, and compliance

Cloud & Infrastructure

  • AWS (primary), multi-cloud strategy
  • Kubernetes and container orchestration
  • Infrastructure as Code (Terraform, Ansible)
  • Observability (Elastic, OpenTelemetry)
  • Network architecture and protocols

Development

  • Full-stack (Vue.js, NestJS, GraphQL)
  • Python, Go, TypeScript, Java
  • Graph databases (Neo4j, Memgraph)
  • AI/ML integration (LangGraph, LangChain)
  • API design and microservices

Frameworks & Methods

  • ISO 27001/27002, SABSA
  • ITIL, IT4IT
  • Enterprise Architecture (ArchiMate, BPMN)
  • DevSecOps practices
  • Agile/Scrum delivery

Industry Experience

Domain knowledge built through delivery, not observation. Each industry brings specific constraints, regulatory requirements, and operational realities.

Telecommunications

Experience across mobile operators, network infrastructure, BSS/OSS systems, subscriber-scale operations, and regulatory compliance. Regional leadership across CEE markets.

Aviation & Critical Infrastructure

European air traffic management modernization, operational technology security, safety-critical systems, and the intersection of IT and OT in regulated environments.

Security & Compliance

Security architecture for regulated financial institutions, compliance frameworks (GDPR, sector-specific), and the security demands of handling sensitive financial data.

Technology & SaaS

Product development from zero to production, startup-to-scale challenges, and building technology platforms. Currently building dethernety, a graph-native security platform.

Engagement Models

Flexible structures depending on your needs. Every engagement starts with understanding the actual problem, not fitting your situation into a predefined package.

Advisory & Reviews

Days to weeks

Focused engagements: architecture reviews, strategy validation, due diligence support, expert assessment of specific challenges.

Architecture Programs

3-12 months

Hands-on architecture delivery: enterprise architecture, security architecture, or complex technical programs requiring sustained senior technical involvement.

Transformation Leadership

3-12 months

Embedded leadership for organizational transformation, technology change programs, or critical initiatives requiring senior executive involvement.

Fractional Executive

Ongoing

Part-time technology leadership for organizations that need executive capability without a full-time hire. CTO, CISO, or architecture leadership.

Have a Challenge in Mind?

The best engagements start with a conversation about what you're actually trying to solve, not a sales pitch. Let's talk about your situation.
