ABOUT THIS EPISODE
Ezekiel Iferia sitsdown with backend engineering leader and test automation specialist JessicaPatel to discuss architecting high-reliability systems for U.S. mortgageliquidity, making Test-Driven Development (TDD) practical under deadlinepressure, and safely integrating AI into enterprise backend pipelines.
With 17 years ofexperience engineering backend platforms across Java, Spring Boot, PostgreSQL,Oracle, and AWS, Jessica leads engineering teams supporting over 1,200 lendersdelivering loan data critical to the American housing market. She unpacks the realityof "Red, Refactor, Green," explains why unit tests acceleratelong-term velocity, and explores how generative AI is shifting engineers fromcode writers into system validation architects.
