What I do

Consulting, architecture and hands-on delivery for organisations that need AI and platform systems to be sovereign, compliant and actually used.

01 Fields of work

Six fields, one standard.

  1. 01 AI

    AI Engineering & Architecture

    From tokens to production: context architecture, retrieval, agents and deployment that survive contact with real data.

    Tokenization and context engineering: budgets, chunking, structured promptsRetrieval-augmented generation (RAG) and knowledge-management AIAgent architectures, tool use and orchestrationPrivate and on-premise model deployment, GPU virtualisation, inference servingEvaluation harnesses, observability and cost controlAI-native development practices for engineering teams
  2. 02 SOV

    Sovereignty & Compliance

    DORA, data integrity, data sovereignty and EU-conform hosting — designed into the system, not audited in afterwards.

    DORA: ICT risk management, third-party risk, resilience testing, incident reportingData integrity: lineage, immutability, verification and evidence trailsData sovereignty: where data lives, who can reach it, and under which lawEU-conform hosting strategies: on-premise, sovereign cloud, hybridEU AI Act readiness: classification, documentation, human oversightAudit-ready documentation as a by-product of engineering
  3. 03 SEC

    Security Behaviour

    Security fails at the keyboard. Assess how people actually behave under pressure, then train and design for it.

    Security behaviour assessments: observation, interviews, simulated attacksSocial engineering resilience: phishing, pretexting, AI-generated deceptionHuman-in-the-loop evaluation of security-critical and AI-assisted workflowsAwareness and behaviour-change training for interdisciplinary, intercultural teamsSecurity culture metrics and reporting for management and regulatorsSecure-by-design review of workflows, roles and permissions
  4. 04 PLT

    Platforms & Infrastructure

    Internal platforms, IT infrastructure and deployment pipelines built to be owned — by your team, on your terms, in your jurisdiction.

    Internal platform and tooling developmentIT infrastructure architecture: compute, storage, networking, identityVirtualisation and containerisation strategies, incl. GPU workloadsDeployment pipelines, environments and release practicesIntegration layers and APIs between legacy and modern systemsMigration from proprietary SaaS to owned or EU-hosted alternatives
  5. 05 UX

    Enterprise UX & Workflow Design

    Dashboards, internal software and AI-assisted workflows that people use because they work — researched, accessible, measured.

    UX research for internal tools: contextual inquiry, task analysis, usability testingDashboard and information design for operations, risk and managementWorkflow optimisation and process redesign around real workDesigning AI-assisted workflows: trust, oversight, error recoveryAccessibility compliance (WCAG 2.2, EN 301 549, BFSG) for enterprise softwareAdoption and efficiency measurement
  6. 06 STR

    AI Strategy & Business Development

    Where AI creates value for your organisation, what it costs, and how to build the capability — decided on evidence, not on vendor decks.

    AI use-case discovery and prioritisation with business casesBuild, buy or partner decisions and vendor due diligenceOperating models: roles, governance, capability buildingBusiness development in AI-driven markets and partnershipsResearch and innovation project consulting (public funding, consortia)Executive briefings and board-level decision support

02 Engagement formats

Four ways to work together.

  • A

    Assessment

    2–4 weeks · fixed scope

    A focused diagnosis of one system, one process or one compliance question. Ends with a written decision memo and a prioritised roadmap.

  • B

    Advisory

    monthly retainer

    Ongoing access for architecture decisions, vendor reviews, regulatory questions and second opinions — for teams that need a sparring partner rather than a project.

  • C

    Build

    6–16 weeks · team embedded

    Hands-on delivery of an AI, platform or internal-tool system together with your engineers, including documentation, tests and handover.

  • D

    Training

    half-day to 3 days

    Security behaviour workshops, AI-native development practices, DORA for engineering teams. Interactive, measured, and tailored to your organisation.

03 How I work

Assess. Decide. Build. Verify.

  1. 01

    Assess

    Every engagement starts with evidence: architecture reviews, interviews, log and data inspection, a look at how people actually work. No slide-ware before there is a diagnosis.

    • Current-state map
    • Risk and opportunity register
    • Decision memo
  2. 02

    Decide

    Options are laid out with their trade-offs — cost, sovereignty, compliance exposure, operational load — so the decision is yours and defensible in front of a board or an auditor.

    • Target architecture
    • Roadmap with checkpoints
    • Build / buy / partner call
  3. 03

    Build

    I work inside your team, not above it: prototypes that become production code, documentation that AI agents and humans can both read, and controls that are designed in rather than bolted on.

    • Working system
    • Runbooks and ADRs
    • Evaluation harness
  4. 04

    Verify

    Behavioural tests, resilience exercises, red-team style reviews and follow-up measurements. If something did not hold up, we learn why and fix the cause — not the symptom.

    • Test evidence
    • Audit-ready documentation
    • Training and handover
