Work Experience
Lead AI Engineer
2023 - 2025
Cased
- Led a team of three engineers trying to find product market fit in the DevOps space with a large language model (LLM)-powered platform.
- Worked with SOTA LLMs to replicate tasks for DevOps engineers. The goal was to build "Cursor" for DevOps.
- Developed an LLM-powered chatbot using OpenAI's Assistants API, with deep integrations into DevOps tools like GitHub and AWS, enabling infrastructure management directly from Slack—an early prototype of a Mission Control Platform (MCP) client.
- Implemented an LLM-based linter to optimize the Terraform infrastructure. The system would detect security issues and cost optimizations to help maintain the Terraform repo.
- Implemented an LLM-based incident management system that suggested code changes to solve bugs in production, integrated with Sentry and GitHub.

Founding Machine Learning Engineer
2021 - 2023
Gantry
- Developed and maintained the integration between the Gantry system and multiple LLM vendors, including OpenAI, Cohere, and Anthropic APIs.
- Designed and implemented a high-level abstraction for LLM prompt configurations to enable customers to do prompt engineering with their LLM.
- Developed and maintained the Python SDK client for data ingestion. Almost all customer production data was ingested into the platform through this SDK, meaning this software was optimized for high performance.

Lead Machine Learning Engineer
2018 - 2021
ASAPP
- Developed a custom deep learning training framework on top of PyTorch called Flambé. I presented it at the ACL conference in 2019.
- Built the entire training pipeline for our machine-learning models using Airflow. The implemented DAGs covered data ingestion, training, model storage, and metrics computation, making the process reliable and reproducible.
- Implemented a model storage and metrics platform for machine learning model comparison.
- Reimplemented our core ML API server, where all machine learning models were deployed. This was designed for high availability in massive traffic loads and implemented with low-level async Python support.
- Interviewed 50+ candidates to grow our engineering hub in Argentina from two people to 80+ people. Evaluated technical skills for different seniority roles and also team fit aspects for culture building.
- Implemented text classification models for intent detection using a supervised learning approach with prototypical architectures that enabled dynamic categories with very few data samples.
- Implemented a training pipeline for sentiment analysis in chat conversations between customers and call center agents to predict customer satisfaction.

Assistant Professor
2017 - 2018
Instituto Tecnológico de Buenos Aires
- Led the practical part of the "Data Structures and Algorithms" course in a 4-hour weekly class for approximately 30 software engineering students.
- Taught how to implement complex data structures and algorithms to consume them—mainly trees and graphs.
- Created all exams for the class and a 3-hour open-book coding challenge with three exercises.
Technologies: Java, Algorithms, Data Structures
Machine Learning Founding Engineer
2017 - 2017
Entelai
- Started the engineering efforts of a founding startup from scratch.
- Built a pipeline for brain imaging disease detection from data ingestion to visualization.

Experience
Lila: AI Testing Framework for Startups
https://lila.dev/I'm the founder of Lila, a QA AI agent for startups. Lila introduces a new way of declaring E2E tests on web applications using human instructions and uses LLMs to run them. Lila is a no-coding testing framework that allows you to test what your users do and not what you code.
Ivy: The Ivy Lee Method for Slack
https://tryivy.app/I created this Slack app that implements the Ivy Lee method for Slack. This method is a productivity hack that has good results in remote teams. I implemented this so that members of a workspace could give visibility on their productivity to their team members.
Deep Brain
https://github.com/iitzco/deepbrainA machine-learning Python library for brain imaging processing. The idea of this library is to provide a basic set of validated and SoTA models for brain imaging processing (MRIs).
Currently, this project is on stand-by due to my lack of availability to continue its development.

Faced
https://github.com/iitzco/facedA near-realtime open-source library for face detection. The goal was to implement a face detection mechanism that could run in simple hardware without needing a GPU.
Currently, this project is not being actively developed due to my lack of time, but it has been gathering positive feedback on the open-source community.
