In June 2025, Marh focused on backend development within the odoo/odoo repository, addressing a nuanced issue in the hr_expense domain related to multi-currency expense reporting. Using the Odoo framework and Python, Marh delivered a targeted bug fix that corrected the display of currency symbols in expense reports, ensuring the company currency symbol appears instead of the expense currency. This adjustment reduced the risk of confusion and audit discrepancies in financial records. The work demonstrated a precise understanding of Odoo’s multi-currency handling and improved the accuracy of expense reporting, though the scope was limited to a single, critical bug fix.
