Profile

Software architect in Cologne with eighteen years of software engineering in Brazil and Germany, from programmer and consultant in enterprise projects to software architecture for digital product passports.

Focus on architectures in which AI components do bounded work under deterministic rules, on semantic interoperability with ECLASS and the Asset Administration Shell, and on evidence that travels with the data.

Architecture focus

  • Governed AI architecture: Separating probabilistic proposal from deterministic permission; confidence gating, human review and replayable decision records.
  • Semantics and interoperability: Data models that keep their meaning across systems: ECLASS, Asset Administration Shell, UN/CEFACT UNTP, JSON-LD.
  • Regulation as engineering input: Turning requirements from the ESPR, the EUDR and the AI Act into architecture, data models and tests.
  • Enterprise delivery: Architecture documentation with arc42, risk analysis, test strategy and agile delivery in large teams.

Technical skills

  • Architecture: Distributed systems, Event-driven architecture, Integration architecture, API design (REST, OpenAPI), arc42, Architecture decision records, Architecture risk analysis, Modernising grown system landscapes
  • Backend: Java, Spring / Spring Boot, Python, FastAPI, SQLAlchemy, TypeScript, Node.js, Next.js / React
  • Platform and delivery: Docker, Kubernetes (K3s, k3d), Terraform, Argo CD / GitOps, CI/CD pipelines, Linux, Tracing and audit trails
  • Data and semantics: PostgreSQL, pgvector, Redis Streams, Kafka / Redpanda, Neo4j, ECLASS, Asset Administration Shell, JSON-LD
  • AI systems: LLM integration, Retrieval-augmented generation, Locally hosted models, Confidence gating and human review, Governed decision architecture, Evaluation and benchmarks
  • Standards and regulation: W3C Verifiable Credentials, GS1 Digital Link, UN/CEFACT UNTP, Digital product passports, ESPR · EUDR · EU AI Act
  • Ways of working: Scrum (PSM I), Kanban, Test strategy and test management, Technical leadership of development teams
