Experience

AI Engineer

CodeGPT | Dec 2023 - Jul 2025

Engineered a knowledge-graph algorithm to analyze codebase structures. You can try it out at deepgraph.co.
Designed a scalable, asynchronous system to build knowledge graphs by orchestrating dynamic AWS ECS tasks, enabling on-demand processing of any size codebase.
Architected the Deno API backend to integrate multiple LLMs with internal tools, serving a production-scale code assistant.
Developed the core logic for autocomplete and code indexation features within the VS Code extension, including building the MCP client.
Architected a containerized on-premise Docker solution, unlocking a new enterprise customer segment by guaranteeing 100% data privacy.
Led the full infrastructure migration from Vercel to AWS, rebuilding the platform on AWS Fargate to improve scalability and reduce operational costs.
Deployed a Qwen coder model on Google Cloud with GPU autoscaling, providing inline code completions to free users while optimizing inference costs.

Data Scientist

Data Science Institute, Universidad del Desarrollo | Apr 2020 - Nov 2023

Developed a national "mobility index" by analyzing massive mobile XDR datasets in BigQuery, which directly informed Chilean government lockdown policies and led to 2 peer-reviewed publications.
Developed a recommendation system for Derco-Chile to drive cross-sales by matching users with similar vehicles.
Implemented Customer Lifetime Value and Customer Journey models using Bayesian inference for Derco-Chile, helping in the development of new products and services.

Research Assistant

National Astronomical Observatory, University of Chile | Feb 2020 - Dic 2022

Developed a novel Approximate Bayesian Computation (ABC) algorithm to characterize Blazar variability, reducing model fitting time from hours to minutes.
Contributed to the Cherenkov Telescope Array (CTA) project by acquiring data and performing redshift classification.

Developer

FONDECYT 11180913 | Jul 2019 - Jul 2020

Developed and published tsnmf, a Scikit-Learn compatible Python package for Topic-Supervised NMF optimized for sparse matrices, used as the core model in a published study on city-wide transportation mode inference.
