PROFILE
Arnab.kumar
Over five months, contributed to the nammayatri and shared-kernel repositories by building and enhancing backend systems focused on SMS delivery, authentication, and messaging. Integrated Karix and Pinbix SMS providers using Haskell and YAML, enabling scalable, provider-agnostic OTP workflows and reducing vendor lock-in. Implemented encryption for sensitive SMS configuration data to strengthen security around OTP credentials. Developed an internal Rider Platform Authentication API, establishing a foundation for token-based access control. Enhanced the messaging system by introducing a message type field for targeted notifications. The work emphasized modular design, cross-repository collaboration, and robust API development to support reliability and future scalability.
