Tech Stack
Challenge

As a startup, AI dating assistant faced the challenge of building a robust and efficient system to support real-time interaction and personalized user experiences.

Initially using Firebase and Firestore cloud functions, the team encountered limitations such as cold starts and the inability to stream LLM outputs in real time. This necessitated a shift to a traditional backend to meet performance demands and provide a seamless user experience.

Solution

To address the performance limitations, AI dating assistant transitioned from Firebase and Firestore cloud functions to a Node.js backend hosted on Railway with a PostgreSQL database. This setup eliminated cold starts and enabled real-time streaming of LLM outputs.

The team evaluated various LLM models, including GPT-4o, Claude 3 Sonnet, and Claude 3 Haiku, selecting models based on their accuracy, latency, and speed for different tasks.

The app was developed for both iOS and Android using React Native, ensuring broad accessibility and a consistent user experience across platforms.
