  • L
    AI Engineer
    LiDARit
    Nov 2023 - Current (2 years 7 months)
    Leading a team in developing multiple systems powered by language models. Impacting over 30,000 university users with our AI professors platform. Implemented several CV AI pipelines for medical image analysis and generative AI projects. Led a team in implementing preprocessing and training pipelines for mineral prediction using Python and Azure ML. Also implemented a web application for training and evaluating prediction models using React, Flask, and Docker. Automated various tasks for database administration
  • Citric Sheep
    Machine Learning Engineer
    Citric Sheep
    May 2023 - Oct 2023 (6 months)
    Led several AI projects solving complex problems such as a medical model to estimate acetabular cup angles to optimize hip CT scans. I had to deploy solutions for critical clients and correct software engineering practices where used in order to have success. Also we implemented AI security systems for a daycare using a test driven development to finetune the models.

    Software Developer
    bld.ai
    May 2021 - Nov 2022 (1 year 7 months)
    I led a development team training a model to predict presence of minerals over Ontario's ground. Used PyTorch is one tool very usefull to train some DNN models and I used it to perform experiments over finding the best model to fit the geospatial data and Azur ML to deploy the model for the customer

    Feb 2024 - Apr 2024 (3 months)
    Implemented a customer service agent to attend querys from the customers using a llm architecture with websocket and django.
  • E
    Estimation of Acetabular Cup Angles
    May 2023 - Sep 2024 (1 year 5 months)
    Built a CNN that estimates the inclination and anteversion angles of the acetabular cup using a single hip X-ray image. Used transfer learning techniques and technologies like Pytorch and OpenCV. FInally it estimated inclination with 82% precision and anteversion with 68%
