Modernising a Public-Sector Infrastructure Application

Modernisation, migration, reporting, and ongoing engineering for SIB-BW2 street-object infrastructure management.

Software engineer — Luis Martin Schick / VertexWare

Situation / problem

SIB-BW2 manages street-object infrastructure for public-sector stakeholders. The application required ongoing feature work, bug fixes, quality work, and migration from an older Java/Karaf runtime to a current stack.

Previous system or workflow

The existing system carried legacy data and reporting requirements across Oracle, PostgreSQL, MySQL, and MSSQL operations. Stakeholders also needed direct German-language coordination and technical documentation.

Solution

  • Worked on the Java 8/Karaf to Java 21/Spring Boot modernisation work.
  • Developed the primary migration tool for the ASB-Object (ASB-ING) standard.
  • Built the majority of the reporting functionality from zero.
  • Delivered bug fixes, features, quality work, stakeholder liaison, and technical documentation.

Concrete result

  • The team is migrating the application from Java 8/Karaf to Java 21/Spring Boot while development continues.
  • The primary migration tool moves legacy data toward the ASB-Object (ASB-ING) standard.
  • I built most of the reporting functionality while the application remained in active development.
