Projects
Two kinds of work live here. First, a selection of anonymised consulting case studies — client-confidential engagements reduced to industry, role, technology and outcome. Below that, the small personal projects I maintain in my spare time.
Consulting Case Studies
Client names are withheld under NDA. Each card states the industry, my role, the technologies involved and the result.
Retail — On-prem to Azure migration
Migrated a VMware ESXi estate to Azure with agentless Azure Migrate. Rebuilt the landing zone as Bicep Infrastructure-as-Code and deployed it through Azure DevOps CI/CD pipelines — including repository security checks and SFTP/SMB/IP data-transfer routing.
Finance — Security overhaul & managed SOC
Hardened a financial-services organisation: hybrid Exchange Online, selection and onboarding of a managed SOC, Defender for Endpoint with Conditional Access and device compliance, and Data Loss Prevention replacing a third-party encryption tool. Reworked the vulnerability-management process throughout.
Staffing — GenAI matching copilot
Built a generative-AI application that matches incoming project requests and tenders to available candidates: key facts and required skills are extracted from each request, candidates selected by semantic search, and their skill sets scored against the requirement. Azure OpenAI, Semantic Kernel and RAG on an ASP.NET Core / Angular stack.
Med-tech — Compliant Azure DevOps
Implemented CI/CD processes that synchronise validated build environments with a cloud Azure DevOps instance, enabling external development teams to integrate while preserving compliance with ISO/TR 80002-2, ISO 13485 and IEC 62304.
Business Central — master-data sync
Synchronised master-data tables across several Microsoft Business Central tenants using narrowly-scoped Azure Functions connected over Service Bus. Change data arrives by webhook; the data model and data-access layer are code-generated from BC metadata.
Personal Projects & Open Source
Tools and libraries I actually use — either at home or to automate my own workflows. You can see all of my personal projects on GitHub.
DevPc – Windows Setup Automation
A collection of PowerShell scripts that fully automate the setup of my Windows machines using WinGet. Includes profiles for work, home, and family setups. Allows me to rebuild a complete environment within minutes — consistent, reproducible, and version‑controlled.
HomeAssistant-SEM
A PowerShell‑based home automation tool. Originally built to experiment with lightweight motion detection and event‑triggered actions.
SEM.WebCamMonitor
A PowerShell‑based webcam monitoring tool that supports my home office work by switching on an "on air" light when I am in a meeting.
AnnaMatzenMusic
Supporting my daughter Anna Matzen with her YouTube channel. Modern music played on analogue instruments (clarinet, drums, piano, guitar).
