Alexander Valderrama Villamarin
@alexandervalderramav
I build AI-ready data platforms and production LLM infrastructure.
ColombiaWhat I'm looking for
At Chromatics AI, I architect the Python/FastAPI data, backend, and API layer for a Generative Engine Optimization platform that tracks brand visibility across OpenAI, Gemini, and Perplexity. I built daily multi-provider LLM pipelines, citation attribution, entity resolution, and analytics powering real-time visibility reporting.
Previously, I spent nine years as the sole architect of Viamericas' analytical platform, building AWS data lakes and warehouses and an ML fraud detection system that reduced fraud by 80%. Across 20+ years, I've delivered data warehouses, BI platforms, predictive models, and AI automations for US and Latin American organizations.
