Worked on access policy tuning within the actualbudget/actual repository, delivering a targeted configuration management feature for the EASYBANK_BAWAATWW integration. The main focus was to enhance security by reducing the access validity period from 180 to 179 days, ensuring tighter control with minimal disruption to users. This adjustment was implemented in JavaScript, maintaining clear code traceability and an auditable change history. The work demonstrated attention to detail in policy management, emphasizing lightweight, maintainable updates rather than broad changes. No bug fixes were required during this period, reflecting a focused approach to incremental security improvements through precise configuration adjustments.
