Nov 1, 2025November 2025 (repo nammayatri/nammayatri): Focused on reliability and predictability of the manual payment flow. Implemented rate limiting for manual payment link sends to drivers and added a maximum delay to prevent late job execution, significantly improving scheduling reliability. Fixed a race condition in the SendManualPaymentLink job to ensure consistent, idempotent messaging and reduce duplicates. These changes enhance system resilience with minimal latency impact while enabling safer external API usage.

Oct 1, 2025October 2025 monthly summary for nammayatri/nammayatri focusing on business value and technical achievements. Delivered a Volunteer Management System enabling creation, listing, updating of volunteers with vendor association and activity status management. Implemented Payment Order Financial Tracking Enhancement by adding an 'effect_amount' column to the payment_order table across two database schemas to support new financial tracking. Fixed Driver Fee Calculation Job error messaging to clearly indicate rescheduling instead of completion, reducing confusion and support overhead. Overall, these efforts improved volunteer coordination, financial visibility, and reliability of driver-related processes, enabling better analytics and decision-making. Demonstrated backend development, database schema updates across multiple schemas, and improved error handling.
