Worked on the nammayatri/nammayatri repository, delivering backend and frontend features that improved user experience, data integrity, and operational transparency. Built and enhanced APIs for ride cancellation, rewards, and cohort eligibility, using Haskell, SQL, and Kafka to ensure type safety, performance, and maintainability. Refined localization and frontend guidance to reduce user confusion, while backend changes unified API contracts, strengthened security, and enabled granular financial analytics. Addressed system architecture by streamlining rewards evaluation and stabilizing dynamic driver pool configuration. The work emphasized traceable commits, robust data models, and compatibility across mobile and dashboard interfaces, supporting scalable, data-driven decision making.

Jul 1, 2026July 2026 — Namayatri: Delivered a two-part enhancement to the rewards system, introducing a robust reward-cohort eligibility validation API and repeatable cohorts, enabling repeatable rewards and safer product logic. Key improvements include type-safe context for cohort eligibility, strict JSON-logic validation, and shared verdict semantics; add-on support for repeatable cohort unlocks (per-rider caps) with a durable DB schema; security hardening to prevent cross-merchant access; and ops tooling integration via cohort create/edit endpoints. Minor maintenance included a migration index fix to avoid blocking commits. Result: more flexible promotions, improved rider engagement, and reduced operational risk.

May 1, 2026In May 2026, delivered a focused backend enhancement for the cancellation dues workflow in nammayatri/nammayatri, introducing an optional per-ride duesBreakup array to the cancellation dues API to provide granular breakdowns while preserving the existing payload for the customer mobile UI. Implemented a new includeBreakup query parameter to enable detailed data for dashboards, with rideId translation from BPP to BAP to support the dashboard waive-off endpoint. Rows without BAP matches are logged and dropped; aggregate totals remain unchanged to ensure data consistency. The change improves transparency for customers and enables more precise financial analytics, while maintaining backward compatibility and minimal impact on the existing UI and integrations. This work lays the foundation for enhanced reporting, visibility, and potential revenue optimization through better cancellation charge insights.

Mar 1, 2026March 2026 monthly summary for nammayatri/nammayatri focusing on business value and technical achievements. Key features delivered include ride end process improvements with data integrity enhancements (removal of GPS toll check and driver-vs-customer verification), a new Waive Cancellation Charges API to improve rider experience and control, and expanded NammaTag/ChakraQueries APIs with richer data exports and performance improvements. A critical bug fix corrected the default behavior of isDriverSameAsCustomer to ensure accurate matching. Additional data enhancements and improved exports and encodings contribute to better performance and data quality for Rider and Provider platforms. These efforts reduce user friction, improve data accuracy, and support scalable data access and decision making across core flows.
