Hi, I'm Hernán Galileo Backend Engineer · Data Engineer · GIS Developer

I build systems that handle scale — from fintech microservices to geospatial pipelines for urban analysis. Currently at Stori and completing a Master's in Urban Planning at UNAM.

What I do

Two areas of expertise

I work at the intersection of distributed systems and geospatial intelligence.

⚙️

Technology Professional

Senior backend and data engineering experience building production systems in fintech and enterprise environments. Specialized in Go, Python, cloud-native architectures, and data pipelines at scale.

Featured Work

REST API that ingests, models, and serves structured geospatial data for Mexico City's public transit network — Metro, Metrobús, Cablebús, and Tren Ligero. Built as a research tool for the UNAM Urban Planning Master's, analyzing CDMX transit infrastructure with spatial queries and GeoJSON outputs.

Transaction API — Backend Challenge

End-to-end Go REST API built as a technical challenge: a migration service that ingests transaction records from CSV into a database, and a balance service that computes user summaries on demand. Fully Dockerized and deployed to Fly.io.

VFT Model — Urban Transit Analytical Engine

Geospatial and topological analytical engine for evaluating ring-shaped and feeder transit networks in Mexico City. Built on a pragmatic hexagonal architecture: FastAPI endpoints, GeoPandas + NetworkX + Momepy for graph computation, and async clients consuming the Apimetro Go API. Powers the quantitative analysis of the TAICMAM thesis at UNAM.

La Historia de Quince

Hernán Galileo Cabrera Garibaldi · Letrame Editorial

Published fiction novel with horror elements. Writing alongside engineering is part of staying creatively sharp — the discipline of storytelling carries over into how I design systems and communicate technical ideas.
