About me
I worked until December 2021 as a machine learning scientist at AITuring supervised by Diego Ismael León Nieto. My role involves re-factorizing the current machine learning pipeline.
I worked until December 2020 as a researcher in electronics, embedded systems, and hardware design at IMaR Technology Gateway supervised by Krishna Panduru. My role involves IoT and embedded systems for industry applications.Obtained my BSc in Mechatronics Engineering from the Universidad Autonoma de Occidente (supervised by Victor Romero). My degree project involved developing a robotics perception system to estimate geometric features in a tree.
Grew up in Santiago de Cali, Colombia in 1994; moved to Tralee, Ireland in 2019 after finishing my undergraduate. Moved back to Colombia in December 2020.

Work Experience
Machine Learning Scientist
Typically work as a member of the AI team that focuses on researching, building and
designing self-running ML systems and tools to detect and classify objects. Identify data
distribution that affects model performance running machine learning debugging and
using results to improve models, developing architectures according to client goals
requirements.
* Re-factorized deep learning models for object detection and classification
* Applied resources in the Google Cloud Platform to test ML pipelines such as Cloud functions, Vertex AI, Buckets
* Improved evaluation metrics such as confusion matrix, accuracy, iou
* Proposed CV alternatives to current base-line
* Doing research on MLOps proposals
* Enabled custom metrics on Tensorboard
Research engineer embedded systems/electronics/hardware design
Under Krishna Panduru guidance, I played a key role in the prototyping laboratory with short-term projects 2-3 months, building, deploying, researching, coding, and documentation that runs on embedded systems to analyze sensors data.
* Managed a vision system for quality inspection using OpenCV
* Demonstrated an interface framework for a ZR300 Intel Realsense camera in PCL and ROS
* Maintained and demonstrated a data science and Industrial IoT project for a human-machine interface to automate quality inspection in biomedical industry
* Adjusted a RFID project to read an animal tag using the RFIDRW-E-TTL with a nRF5 SDK 16.0
* Completion of a CMake project for the nRF52 SDK to program an nRF52832 using JLink
* Developed, modified and debugged an IoT application for getting the strain deformation data of a gauges sensor using an ESP32 micro-controller and the esp-idf framework.
Selected Projects
Density-based spatial clustering of applications with noise (DBSCAN) is a data clustering algorithm
This project is a photogrammetric system for dendrometric feature estimation of individual trees. The purpose of this project is to do a 3D reconstruction of an individual tree using Open Multiple View Geometry (openMVG) and get dendrometry estimation (diameter at breast height (DBH), tree crown height, total tree height, crown volume, morphic factor and percentage canopy missing) of a stem tree
C++ application to convert pcd file, ply file, txt file or xyz point cloud to MESH representation (Gp3).
