WMC Sinterstar AG - Aufbereitung
- Migrated legacy dBase programs for material recycling calculations (charge mixing, analysis, recycling, and stock management) into a modern Elixir/Phoenix LiveView application.
- Ensured functional parity with the legacy system through rigorous validation of 41 conditional branches and 321 automated tests, including a custom-built Elixir library for reading dBase files.
- Used Claude Code (primarily the Opus model) as an AI pair-programming assistant throughout the migration, accelerating implementation while keeping full control over design and validation decisions.
