Every project in this portfolio runs in production, is verifiable via live status, and states precisely which work is my own and which was created in collaboration with Claude AI, Claude Code and Claude Cowork.

Dolibarr tickets did not scale for structured customer support with SLA requirements. Full-text search, escalation logic and multi-client capability were missing.
Self-hosted Zammad on Coolify: Traefik routing, Elasticsearch full-text search, Level.io RMM integration, Grafana alert relay and connection to the two-track Restic backup concept.

The work in this portfolio is created throughout with Claude AI, Claude Cowork and Claude Code — in a fixed, disciplined workflow. The share per project is stated on each card.
Claude AI and Claude Cowork for web research, source cross-checking and document work — organised in Claude Projects with project-specific instructions, following the evidence principle: no statement without a source.
Claude Code for agentic multi-file coding with Git discipline — governed via CLAUDE.md files and own skills, connected to external systems through self-built MCP integrations. Secrets are delivered programmatically from Infisical (machine identities); credentials never appear in plain text.
Every AI output is verified before it counts: BVL acceptance, monitoring via Prometheus/Grafana and multi-workstation governance via claude-workstation-sync.
Three principles make this portfolio verifiable rather than declarative.
Every figure carries its evidence: publicly verifiable sources are linked, internally evidenced ones are marked as such. Market values show their calculation method — SaaS list price comparison (via swcalculator) or effort × market rate, never a bare number.
Every project states AI contribution and own work separately. Verifying AI outputs is always own work — the core of responsible AI collaboration.
Five criteria, no in-between: factually correct, enterprise-grade, externally auditable, standards-compliant, complete. Only 5×1 appears here.
