now: ICASA — Guatemala
bow: recurve · 30 m
title: national champion
base: Lima, Peru

I design data architectures on Databricks and BigQuery, and push AI into them until the team’s operation stops being the bottleneck. Also: national recurve archery champion at 30 m — yes, I aim well in both senses.

ES — Senior AI Data Engineer. Construyo plataformas de datos sobre Databricks y BigQuery, les monto agentes LLM encima, leo demasiada política internacional y tiro con recurvo. Esta web es mi escritorio; abre las ventanas, rompe algo.

01 / WHAT I DO

Cloud data platforms, pipelines that stay up, and LLM agents that survive production.

02 / WHAT I READ

International politics and finance. Two ways of watching systems fail live.

03 / WHAT I SHOOT

Recurve. 30 metres. National champion. The only deploy with no rollback.

This site is my desktop. Every icon opens a window; one at a time, as it should be. The full CV lives in cv.pdf and exports for real. The terminal lives below — type help.

And it is not a prop: type python scoring.py --demo and you will watch a real CPython 3.14 run, compiled to WebAssembly and executing in your browser. There is no server on the other end: the interpreter downloads in full and runs on your machine. Type python on its own and the REPL opens.

AUGUST 2026 — WHAT I AM DOING

Four things are on my mind

Senior Data Engineer at ICASA (Guatemala, remote): moving on-premise workloads to BigQuery and Databricks without the compute bill exploding.

Studying Data Science at Continental University of Florida, alongside work.

Training for the next nationals. Target: never drop below 300 at 30 m.

Reading about monetary policy and why nobody can agree on it.
