I introduce assertion-based unit tests and methods to capture real-world input data, enabling effective analysis of customer interactions. I highlight the importance of structured outputs with the Instructor library and demonstrate how multiple assertions can validate system responses. Additionally, I discuss organizing code for better maintenance and recommend the observability platform Langfuse for tracking API calls. Finally, I share insights on a boilerplate project for event-driven LLM applications and tips for developers transitioning into freelancing.
