KraneKredit
Architected and deployed a high-performance credit scoring API utilizing FastAPI, Python 3.12, and async SQLAlchemy, structuring the codebase with clean architecture principles to strictly decouple domain logic from infrastructure.. Engineered a secure multi-tenant architecture, implementing a dual authentication system (JWT for user workflows, X-API-Key for B2B lender integrations) with role-based access control (RBAC) to safely partition data across institutions.. Built an automated bank statement processing pipeline, developing reliable file upload and management systems, background data extraction tasks, and transaction pattern detection algorithms to feed feature sets into the core scoring models.. Designed a scalable asynchronous job processing system utilizing Redis and ARQ to offload heavy workloads-such as ML model inference, data extraction, and webhook delivery-ensuring optimal latency for the main API server.. Integrated Explainable AI (XAI) and generative insights by incorporating SHAP for model transparency and LiteLLM for generating actionable financial advice and readable score factors for end consumers.. Developed a robust data persistence and versioning layer using PostgreSQL and Alembic, introducing custom Base models with soft-delete capabilities and transaction-safe interactions.. Streamlined developer operations and system orchestration by containerizing the entire stack with Docker Compose and creating extensive Makefile configurations for database migrations, testing, and unified service deployment.
