ERP Dashboard Data Fix

We currently operate an ERP system that has recently encountered issues due to changes in the underlying data format. As a result, the dashboard is displaying incorrect or inconsistent data, impacting daily operations and reporting accuracy. We are seeking an experienced developer to quickly assess and resolve these issues within a short timeframe.
The primary scope of work includes correcting the dashboard to ensure all data is accurately displayed in alignment with the updated data structure, as well as implementing or fixing the email functionality to enable reliable sending of system data via email (e.g., reports or notifications).
The engagement will focus on efficient, targeted fixes without major system redesign, ensuring minimal disruption to existing operations.
Deliverable Conditions:
 All fixes must be fully tested and validated before delivery. The dashboard should display accurate, real-time (or near real-time) data without errors, and all previously identified issues must be resolved. The email functionality must be properly configured and tested to ensure successful delivery without failures or formatting issues. The developer is expected to provide clean, maintainable code, along with basic documentation or a brief handover explaining the changes made. Final delivery will be considered complete only after successful user acceptance testing and confirmation that the system is functioning as expected.
