Worked on the nammayatri/nammayatri repository, delivering features and fixes focused on backend reliability, automation, and data quality. Built and enhanced systems for bus ETA accuracy, pass expiry reminders, and customer unblocking, using Haskell, Dhall, and YAML for robust API development and configuration management. Introduced a simplified data model for nearby buses, improved route metadata, and automated notification workflows through job scheduling and notification systems. Addressed scheduling reliability by implementing cursor-based incremental processing. The work emphasized maintainable code, clear observability, and operational efficiency, reducing manual intervention and supporting a more responsive, reliable experience for both users and operators.

Jun 1, 2026June 2026 (2026-06) monthly summary for nammayatri/nammayatri: Delivered PassExpiryReminderMaster Scheduling Cursor Enhancement, introducing a cursor value in jobData to enable incremental processing and improved scheduling reliability. Implemented a targeted fix to the schedulerTrigger jobData to align with the new cursor semantics. This change enhances timely pass expiry reminders, reduces retry loops, and improves fault tolerance. Demonstrated solid back-end scheduling work, concise commit hygiene, and maintainable changes with clear business value.

Jan 1, 2026January 2026: Delivered Rider Application UnblockCustomer Job Type support for nammayatri/nammayatri. Implemented via a dhall configuration update to enable the rider-app to handle customer unblocking tasks. Also fixed a blocking dhall config to run rider-app, enabling the feature in CI/CD and production pipelines. This work reduces manual intervention, speeds up customer unblocking, and improves operational efficiency.

Aug 1, 2025Month: 2025-08. Delivered two feature families for nammayatri with a focus on data cleanliness, richer route metadata, and improved observability, driving clearer UI and more reliable routing data for riders and operators. Nearby Buses enhancements introduce getSimpleNearbyBuses with a simplified data model, refined service type mapping, improved error resilience, and enhanced observability, enabling a UI that cleanly displays current location, route code, vehicle number, and service type. Bus Routes work adds live tracking availability and richer route metadata (AvailableRoutesInfo with a liveTracking flag, routeShortNames) and updates to route finding to support string service types. These changes improve data quality, UI reliability, and decision-making for riders and ops.

Jul 1, 2025July 2025: Delivered a reliability improvement for bus ETAs in nammayatri by fixing an ETA display issue in the nearby buses feature. Removed an unnecessary timezone conversion and used the arrivalTime field directly, ensuring ETA reflects real arrival times for nearby buses. This change reduces user confusion, improves trust, and lays groundwork for future ETA enhancements.
