Grab a Pint With Django-MongoDB-Backend, Voyage AI, and LangChain

April 19, 2025 Anaiya Raisinghani

DjangoCon Europe is just around the corner, and this year, it’s in Dublin, Ireland. This means two things:

1. I’m legally required to drink my first Guinness (yes, first ever!).
2. I obviously had to build an app to help me find the best pubs to accomplish my Guinness goal.

This full-stack, AI-powered Dublin City Center Pub Finder app is built using our new Django MongoDB Backend Python package, Voyage AI embeddings to best understand the queries, and LangChain to power our natural-language interface.

So, if you’re in Dublin and you really want a “Guinness, outside, with live music,” this Pub Finder will help you find the three best options!

Before we go into how it works and how you can build it yourself, let’s go over the platforms used.
