October 2025 focused on enabling marketplace-style payments in nammayatri/shared-kernel by delivering Stripe Platform Charges Support. Delivered a feature that differentiates between platform charge destinations (platform vs connected account), refactored payment intent creation logic to support both scenarios with the correct parameters, and updated Stripe configuration and payment intent request types to accommodate the new functionality. This work enhances payment routing flexibility, reduces downstream integration complexity, and prepares the kernel for multi-party charging flows.

Month: 2025-09 — Concise monthly summary of key deliverables, impact, and technical growth across the NamMayatri repo. Key features delivered: - Fleet-Level Coin Event Blacklist: Implemented FleetConfig field blacklistCoinEvents and extended enforcement to fleet level in addition to driver controls, preventing specific coin events from awarding coins. This enhances policy compliance and reduces revenue leakage. Commit baae44742eb80d7fb289f12cfbe55c44bd5a13ee. - Driver Document Onboarding for International Documents: Added API and database support for onboarding common driver documents, enabling international document types and updating handling logic for broader global eligibility. Commit ab7cd275d3ae33a1bba4d32093080c772de89481. Major bugs fixed: - Dynamic Offer Booking Duplicate Prevention: Ensured a dynamic offer trip is not already booked before accepting a driver quote; prevents accepting a ride request if an active booking exists for the same transaction ID and status. This reduces double-bookings and improves reliability. Commit 93f351deeef53823ca6f57dd6b3844626738dadc. Overall impact and accomplishments: - Strengthened policy enforcement and financial integrity by extending coin-event controls to fleets and preventing duplicate bookings. - Accelerated global driver onboarding readiness by adding international document support, aligning with expansion goals. - Improved reliability and user experience for dynamic offers, reducing negative outcomes from duplicate quotes. Technologies and skills demonstrated: - API and DB schema evolution (FleetConfig, documents table) - Server-side validation, transactional checks, and feature-flag-like enforcement patterns - Clear traceability with commit-level references for each delivery
