About Patrick

I am a Solution Architect who has journeyed from hands-on medical technology to the strategic architecture of national non-profit healthcare systems. This journey has taught me that the best technical solutions emerge when you understand both the workbench and the C-level.

What drives me is the conviction that technology must serve people – not the other way around. That's why I approach every project systematically: First, I understand the problem, then the people who have to work with it, and only then do I develop the technical solution.

My approach combines proven methods like Domain-Driven Design and Event Storming with modern technologies like AI and cloud infrastructures. I don't believe in universal solutions – every problem needs the right architecture. Event-driven systems are powerful for complex, asynchronous processes, but not every system needs events. Sometimes a simple REST API is the better choice.

In team leadership, I focus on transparency and shared understanding. Architecture is teamwork. The best decisions arise when all stakeholders understand why we are doing something in a particular way. That's why I invest a lot of time in Event Storming workshops and architecture documentation according to arc42.

What particularly fulfills me is working on systems that truly make a difference. Whether it's national healthcare standards for millions of patients or secure infrastructures for critical business processes – I enjoy working where quality and reliability allow no compromises.

My conviction: Good architecture arises from methodical approaches, clear communication, and the courage to find the right solution for the specific problem – not the trendiest one.

    LUXURY GOODS
    December 2024 - Today (1 year and 6 months)
    Berlin, Germany
    As a Solution Architect and Project Manager, I am leading the strategic digitalization of TresorHaus into the digital age. The challenge: Combining the highest security requirements with state-of-the-art cloud technology – for 49,000 safe deposit boxes and their customers in a startup environment.

    My Approach:
    Through Event Storming, I understand the business processes, then define measurable quality goals with stakeholders such as "10,000 safe deposit box orders in under 2 seconds." I document every elementary architectural decision in ADRs according to the arc42 standard and test against these goals.

    Technical Challenges:
    - Hybrid cloud architecture (Public/Private Cloud) for maximum security
    - Multi-CSP architecture with Event Mesh across provider boundaries
    - Integration of multiple locations and comprehensive ERP software implementation
    - Protecting legacy systems with Anti-Corruption Layer
    - Zero-Trust security architecture

    Core Responsibilities:
    - Strategic ERP software selection and implementation
    - Technical and disciplinary team leadership with Scrum methodology
    - AWS infrastructure design and cloud integration (EC2, S3, Lambda, SQS, Redis)
    - Domain-Driven Design, Quality-driven Development, and PoC development
    - Requirements Engineering and Stakeholder Management
    - Event-driven systems with Apache Kafka and Event Mesh

    Technologies:Apache Kafka, Event Mesh, AWS Cloud Services, ERP Systems, Docker, Event-Driven Architecture, Domain Driven Design, arc42, Quality-driven Development

    What drives me: Creating systems that demonstrably work and make people's lives easier.

    Technical Challenges:
    - National integration of all Swiss healthcare facilities
    - Multi-stakeholder architecture (cantons, hospitals, doctors, pharmacies)
    - EPDV-EDI compliance, IHE profiles, and FHIR implementations
    - Quality Gates definition and end-to-end testing
    - Analysis and technical implementation of legal amendments

    Core Responsibilities:

  • AKROS AG
    Solution Architect
    DIGITAL AND IT
    May 2023 - July 2024 (1 year and 2 months)
    Biel, Switzerland
    At AKROS, I led the modernization of Requirements Engineering through AI-powered automation – a project that transformed how we define and validate quality requirements.

    My Main Focus:
    The development of an AI tool that automates Requirements Engineering, generating high-quality scenarios. Instead of weeks of manual work, teams can now create precise, testable (quality) requirements in hours.

    My Approach to AI Integration:
    I don't believe in using AI as a black box. That's why I developed the tool to support, not replace, proven Requirements Engineering methods. The AI generates suggestions, but subject matter experts always make the final decisions.

    Technical Innovation:
    -AI-powered Requirements Engineering:Automatic generation of quality scenarios based on domain knowledge
    -Event Mesh Center of Expertise:Establishment and leadership of Event Mesh competence for integration into complex system landscapes
    -Workshop Facilitation:Systematic architecture evaluation through ATAM, Quality Storming, and Event Storming

    What Makes Me Particularly Proud:
    The measurable and significant increase in development process efficiency. Teams that previously took weeks for requirements analysis now accomplish it in days – with better quality results. In parallel, I established Event Mesh as a central competence within the company.

    Core Responsibilities:
    - AI tool development for Requirements Engineering automation
    - Leadership of architecture workshops (ATAM, Quality Storming, Event Storming)
    - Establishment and leadership of the Event Mesh Center of Expertise
    - Modernization of quality assurance processes

    What drives me: Using AI to support people in creative work, not replace them – better quality through intelligent automation.
