PROFILE

Ratnadeep-99

Ratnadeep Bhattacharjee contributed to the nammayatri/nammayatri and nammayatri/shared-kernel repositories by building and refining backend systems focused on reliability, observability, and data integrity. He developed features such as enhanced API logging, fare calculation logic, and driver verification flows, using Haskell, SQL, and Kafka to ensure robust data handling and traceability. His work included schema evolution for driver operations, integration of external SDKs, and the introduction of metrics for job management in GCP environments. By addressing both feature delivery and bug fixes, Ratnadeep demonstrated depth in backend development, distributed systems, and functional programming, improving operational visibility and system resilience.
