01 / CONTEXT

What the team needed.

Regulated energy-market communication requires precise business rules, valid message structures, and auditable data. At Leitnetz, my current work focuses on translating these requirements into maintainable microservices and backend workflows.

What I worked on.

Services around business rules

Designing Java Spring Boot microservices and REST APIs for regulated energy-market communication.

Rule-driven message validation

Building EDIFACT processing and validation flows for UTILMD, MSCONS, and INVOIC messages, with a focus on AHB/MIG compliance and data integrity.

Traceable workflow state

Implementing persistence with PostgreSQL and JPA/Hibernate, with Liquibase-managed schema changes for reliable workflow state tracking.

AI-assisted analysis

Integrating an LLM/agentic AI sidecar for message validation and error analysis, while contributing to API contracts, authentication, authorization, and service integration.
