About David

When processes between your tools run manually, automations are unstable, or integrations become cluttered over time, I help you build clearly structured workflow systems.

I am a Workflow Architect with a focus on n8n, API integrations, and scalable automation architectures.
I don't just connect tools – I design resilient, modular systems with clean logic and understandable structure.

Typical projects:

• API integrations between SaaS systems
• Process automation for internal operations
• CRM and lead routing workflows
• Reporting and data aggregation solutions
• Webhook architectures
• Migration from Zapier/Make to structured n8n setups
• Error handling, monitoring, and logging

My approach is system-oriented:

• Clear input/output structures
• Modular design instead of workflow spaghetti
• Scalability for growing requirements
• Clean documentation
• Stability under change

The goal is not a short-term "automation solution," but a structured system that works reliably and grows with your company.

    CONSULTING AND AUDITS

    Styria, Austria
    Founder and technical systems architect focused on structured, modular system architectures and automated control processes.

    Conception and implementation of a modular OS-based system model (Structure, Compliance, Evidence, Automation, Governance) for the technical structuring of digital work environments.

    Focus areas of technical implementation:

    • Architecture of n8n-based automation systems (macro orchestration + micro modules)
    • Development of deterministic workflow structures with clear input/output logic
    • API integrations and webhook-based process architectures
    • Automated reporting and export logics (structured JSON/PDF outputs)
    • Role and permission modeling at the system level
    • Building reproducible evidence and documentation structures
    • Versioning and structured artifact storage

    Focus is on systematic architecture, modularization, and long-term stability rather than ad-hoc automation or IT support.
