AI-Powered Event Discovery for Buenos Aires
A conversational AI platform that solves Buenos Aires' fragmented event landscape by aggregating data from 5+ sources and enabling natural language discovery. Built with Claude AI, semantic search via pgvector, and a multi-source import pipeline to help users find everything from underground techno parties to traditional tango milongas.

// The Challenge
Buenos Aires has a thriving nightlife and cultural scene, but event information is scattered across incompatible platforms: Instagram stories, Facebook events, Eventbrite, Passline, venue websites, and WhatsApp groups. There's no single source of truth, making it nearly impossible to discover what's happening tonight.
Traditional search doesn't work for events. Users want to ask questions like 'romantic jazz spots in Palermo' or 'underground techno this weekend' - queries that require understanding intent, vibes, and context rather than just keyword matching.
// The Approach
Built a conversational AI agent using Claude that understands natural language queries about events. Users can ask 'What's happening tonight?' or 'Find me a free outdoor concert' and get intelligent, contextual recommendations.
Implemented semantic search using OpenAI embeddings stored in PostgreSQL with pgvector. Events are embedded based on Spanish descriptions, enabling cross-language similarity matching that captures mood and atmosphere beyond keywords.
Created a 7-step import wizard that aggregates events from Passline, Eventbrite, BA Tourism, and Meetup. Includes smart venue matching, AI-powered description enrichment, and automatic categorization using Claude Haiku.
Designed a bilingual system (Spanish/English) with Paraglide JS, where Spanish descriptions power the semantic search while English translations serve international users.
Built a complete admin dashboard with bulk operations, data quality tools (duplicate detection, address analysis), and background AI enrichment with real-time progress streaming.
// The Outcome
Deployed a production RAG application with 800+ events and 190+ venues aggregated from multiple sources. The AI agent successfully handles complex queries combining semantic search with structured filters.
Achieved sub-second response times for semantic search by leveraging pgvector's IVFFlat indexing on 1536-dimensional embeddings, with server-side filtering reducing post-processing overhead.
Established a repeatable pipeline for event data acquisition: scrape sources, match venues, enrich descriptions with AI, generate embeddings, and serve via conversational interface.
Demonstrated full-stack AI engineering capabilities: prompt engineering, RAG architecture, embedding pipelines, streaming responses, and tool-use patterns with Claude.
