During March 2025, Carson developed the Wallet Fee Tracking Foundation for the moovfinancial/moov-go repository, focusing on backend development using Go. Carson introduced the WalletTransactionSourceTypeFee constant, enabling wallet transactions to be categorized by source and laying the groundwork for future fee analytics and reporting. This technical approach used constant-based categorization to support extensible transaction tracking, improving the system’s readiness for analytics and billing workflows. Carson’s disciplined commit practices and clean, incremental changes enhanced codebase maintainability. The work addressed the need for accurate revenue attribution and financial visibility, providing a robust foundation for future reporting and fee-tracking features within the wallet system.
