Hi, my name is

Alvaro Leonardo Garcia Arroyo

Applied Data Scientist | Brand measurement in generative AI engines

I build measurement systems that say when a movement in the data means something, and when it is just noise

About me

Applied Data Scientist. Six years building measurement systems on marketing, financial and public health data: deciding what to measure, with which method, and when a movement means something rather than being noise. Today, at LLYC, I am responsible for brand visibility measurement in generative AI engines (ChatGPT, Perplexity, Copilot, Google AI Overview) for more than 13 brands across six markets in Latin America and North America. I design the audit method, the prompt sets, and the criteria that decide whether a movement is attributable to the brand or is the engine moving on its own. My background is applied time series econometrics, which I also teach at UPC: ARMA, GARCH, VAR, VECM and machine learning for time series. I also collaborate on the agentic workflows the team uses to deliver to clients, and I do research at the RIEF. Here are a few technologies I've been working with recently:
  • Python
  • Tensorflow
  • R
  • Git/Github/Control-Version
  • DAX
  • SQL
  • Power BI
  • Brandwatch
  • Power Query
  • Power Pivot
  • Excel
  • Econometrics

Experience

Deep Learning Consultant - LLYC - Llorente y Cuenca
August 2024 - present
Technologies used: Python, R, Power BI, Power Query, DAX. Responsible for brand visibility measurement in generative AI engines (AEO/GEO) for more than 13 brands across six markets in Latin America and North America: Alicorp, Gentera, Compartamos Banco Mexico, Concredito Mexico, Yastas Mexico, Aterna Mexico, Banco Popular Dominicano, Honda Mexico, Acura Mexico, Inter-American Development Bank, Bimbo Mexico, Bimbo Canada and Grupo Roggio Argentina.

I also coordinate teams of 2 to 3 analysts on roughly a third of the projects.
