Critical infrastructure · Data sovereignty · Technical integration

I build things that scratch my own itch — local-first, data-sovereign, occasionally over-engineered.

About Skadi Labs

Systems Integrator bridging hardware, software, and carrier operations through technical storytelling and data sovereignty.

Currently at Landis+Gyr: securing mission-critical energy infrastructure and ensuring security of supply for utility networks. High-trust systems where failure isn't an option.

15+ years across technical escalation, field application engineering, DevOps, and security operations. Sonos (8 years), Wirepas (IoT mesh networking), now hardening systems at the grid edge.

Writing & Projects

Technical deep dives on hardening systems, building sovereign infrastructure, and solving real integration challenges. Code, architecture decisions, and implementation details—no fluff.

Topics I write about:

  • Mission-critical systems and technical operations
  • Sovereign AI and local-first data orchestration
  • Self-hosted infrastructure and data sovereignty tools
  • IoT security, hardened architecture, and grid-edge systems
  • Music technology and audio processing
  • Home lab experiments and sovereign infrastructure

How I Can Help

Selective consulting for high-trust, mission-critical environments. If you're hardening systems, ensuring sovereignty, or building technical resilience—let's talk.

Technical Operations & Mission-Critical Systems

Hardening systems where failure isn't an option

I've built technical operations for high-trust environments—energy infrastructure, IoT deployments, carrier integrations. Not theory, actual implementation of hardened processes, incident response frameworks, and technical resilience systems.

What I bring:

  • Hardened process design for mission-critical operations
  • Technical integration frameworks bridging hardware, software, and carriers
  • Security-of-supply architecture for critical infrastructure
  • ISO27001-informed incident response and operational resilience
  • High-trust technical storytelling for complex stakeholder environments
Best fit for
  • Critical infrastructure operators (energy, utilities, industrial IoT)
  • Organizations integrating hardware, software, and carrier operations
  • Companies building high-trust technical operations from the ground up
Not a good fit for
  • Basic IT operations or standard SaaS deployments
  • Consumer-facing systems without regulatory requirements
  • Short-term firefighting (I build systems, not temporary fixes)

Sovereign AI & Data Orchestration

Local-first AI that keeps your data sovereign

I build AI systems that deliver value without surrendering data sovereignty. Hardened pipelines, local-first architectures, and practical automation that enhances operations while keeping sensitive data under your control.

What I bring:

  • Local-first LLM deployment for data-sensitive environments
  • Sovereign data pipelines that never leave your infrastructure
  • Hardened automation workflows with proper access controls
  • Technical documentation systems using AI without cloud dependencies
  • Practical implementation (I write the code, not just strategy decks)
Best fit for
  • Organizations with strict data residency or sovereignty requirements
  • Critical infrastructure operators needing AI without cloud exposure
  • Teams wanting to leverage AI while maintaining operational security
Not a good fit for
  • Generic chatbot or customer service automation
  • Organizations comfortable with cloud-only AI solutions
  • Projects without existing infrastructure to build upon

Technical Storytelling & Integration Training

High-trust technical communication for complex systems

I've delivered SDK coaching, API onboarding, and technical integration workshops across Europe, Asia, and North America. Specializing in bridging hardware, software, and carrier operations through clear technical storytelling.

What I bring:

  • Integration training programs for hardware/software/carrier systems
  • Technical workshop facilitation for mission-critical deployments
  • SDK/API documentation and onboarding for high-trust environments
  • Cross-cultural technical communication (15+ countries, utility and industrial sectors)
  • Field application engineering perspective from grid-edge deployments
Best fit for
  • Critical infrastructure vendors launching integration programs
  • Organizations bridging OT/IT for industrial or utility deployments
  • Teams requiring technical enablement for high-trust stakeholders
Not a good fit for
  • General corporate training or soft skills workshops
  • Consumer-facing product education
  • Ongoing training program management (I design and launch, not run indefinitely)
