Worked on enhancing access rights validation within the roXtra/processhub-sdk repository by refining TypeScript type definitions to create more explicit and robust user permissions checks. Focused on improving the reliability of the rights management module, the work addressed a specific bug related to authorization errors following a TypeScript update. The approach involved targeted adjustments to type handling, ensuring stricter contracts for access control logic while minimizing the impact on existing code. By leveraging TypeScript and expertise in access control and module management, the changes reduced the risk of regressions and contributed to a more predictable and stable permissions validation process.
