Can you describe a time you faced a challenge while working on a Flutter project and how you resolved it?

I encountered a performance issue when rendering a large list of items using ListView. I resolved it by implementing ListView.builder, which only builds visible items, significantly improving performance.

🏷️
How would you design a prompt architecture that optimizes the retrieval of contextually relevant information while minimizing the computational cost in a large language model system?

I would employ a layered prompt design that includes context windows and dynamic prompt chaining to ensure relevant data is retrieved efficiently. Additionally, I would implement caching mechanisms to reduce…

🏷️
How would you design an Express.js application to handle a large number of concurrent requests efficiently, particularly focusing on performance and scalability?

I would utilize middleware for request handling, implement load balancing by distributing traffic across multiple instances, and integrate caching strategies for frequently accessed data. Additionally, using asynchronous programming features of…
