Arpita Raut developed core digital banking API capabilities for the joshsoftware/lingo.ai repository, focusing on secure payment workflows, beneficiary management, and enriched transaction insights. She designed and implemented data models for customers, accounts, and transactions using Python, FastAPI, and SQLAlchemy, enabling robust balance checks, payments, and transaction history features. Her work included refactoring payment flows for improved beneficiary resolution, introducing OTP-based security, and enhancing API responses with customer details. Arpita also improved data generation for spending analytics and intent detection, while migrating sensitive configurations to environment variables, resulting in more reliable deployments and deeper, data-driven financial insights for client applications.
