PROFILE

Pranav Sathya A R

Over eight months, contributed to the nammayatri/nammayatri platform by designing and delivering 22 backend features focused on public transport operations, pricing, and data integrity. Leveraging Haskell, Rust, and Redis, developed APIs for vehicle scheduling, fare calculation, depot management, and live tracking, emphasizing type safety and robust data modeling. Enhanced system reliability through multi-cloud data fallbacks, cache optimizations, and Kafka-based GPS throughput improvements. Extended analytics capabilities and improved onboarding flows while maintaining compatibility and operational security. All work was delivered through end-to-end implementation, with careful attention to data correctness, extensibility, and traceability across multiple repositories and cloud environments.

November 2025: Delivered API exposure and data-context improvements for depot and dispatcher workflows in nammayatri/nammayatri. Implemented Depot and Dispatcher API endpoints to retrieve depot names, IDs, vehicles by depot, plus getDepotNameById and dispatcher history data flow. Strengthened authentication/authorization with depot context (depotCode) and depot admin status, including operator checks and robust Redis key handling for fleet updates. Advanced the Vehicle and Data Model with depotIds typing changes, improved vehicleDetails and history handling, and waybill support. Enhanced Fleet Persistence with longer Redis TTL and refined service tier mapping for accurate route-code-to-service-code alignment. These changes reduce operational risk, accelerate fleet and dispatch operations, and enable more precise access control and data insights.

August 2025 — Key feature delivery for nammayatri/nammayatri focused on pricing accuracy for stage stops. Delivered a Stage Stop Flag and Fare Calculation feature to account for stage stops in pricing. The work extended the data model and the calculation pipeline to include an isStageStop boolean on RouteStopTimeTable and ensured its parsing feeds into the fare calculation logic. Commit 2e0bf553502132bffa21d2f7167c15e6cc2e976b documents the backend changes. Major bugs fixed: No separate bug fixes reported this month; effort centered on feature delivery and integration across data model and pricing logic. Overall impact and accomplishments: Improved fare accuracy for routes with stage stops, enabling fair pricing, better revenue tracking, and the foundation for future analytics on stage-stop pricing. This work adds business value by aligning pricing with actual stop patterns and demonstrates solid end-to-end delivery from data modeling to calculation. Technologies/skills demonstrated: Backend data modeling (RouteStopTimeTable), parsing enhancements, pricing algorithm adjustments, end-to-end implementation, and change traceability via commit references.
