This presentation highlights a backend engineer's journey in optimizing financial data analysis by advancing from basic CRUD operations to sophisticated SQL features. Faced with the challenge of slow API responses due to extensive database interactions, a novel approach was adopted—transferring computational processes directly into the database. This shift not only streamlined data retrieval through single SQL queries but also enhanced performance by exploiting SQL's advanced functionalities like Materialized Views, CTEs, and Window Functions. The initiative not only significantly reduced API response times but also minimized development and maintenance overhead, demonstrating the power of advanced SQL in backend optimization and the importance of embracing database capabilities for system efficiency.
