Juan de la Fuente

Analytics Engineer

I design and build production data systems. Pipelines, APIs, models, and interactive products that turn data into decisions.

Before engineering data, I ran a business. That experience shapes every system I build — from understanding the real problem to shipping something that works.

How I approach data problems

01

Understand

Map the business context, identify the decision that needs better information, and define what success looks like.

02

Model

Design the data architecture. Source ingestion, transformation logic, storage, and access patterns before writing production code.

03

Build

Implement pipelines, APIs, and interfaces. Prioritize reliability — tests at every layer, validation at every boundary.

04

Measure

Validate output against the original business problem. A pipeline that runs is not the same as a pipeline that delivers value.

Background

I ran a business before I built data systems. Managing inventory, costs, logistics, and margins taught me that data is only valuable when it helps someone make a better decision. That principle guides every system I design.
