Developer
Skills
During the last years I have taken courses that range from neural networks to devops, learning from artificial intelligence models to creating applications for mobile phones.
Developing
Technology
In recent years, my work has led me to learn new technologies to solve our artificial intelligence challenges, my focus has been from data scientist to machine learning engineer. I have trained a model to get the demo of an app just to find a way to solve this challenge, that has led me to know each of the following technologies

Jose Alberto Ramos Rojas
If you ask me why I do what I do, the answer is simple, since I was a child I have always been attracted to the question of why things work the way they do, driven by that simple and simple question that has led me to this moment.

Education
Angular Avanzado
2021 - 2022
Udemy Online
The accelerated growth of applications and my own interest in the development of applications with AI led me to learn this language to be able to use it in Ionic
Apply Generative Adversarial Networks (GANs)
2020 - 2021
Coursera Online, Deeplearning.ai
It is one of the places where I take long courses to delve into artificial intelligence issues, in the same way the rest of the online pages that increased their traffic during the pandemic, including platzi, udemy and university channels.
Machine Learning Specialization
2020 - 2020
Coursera Online, Deeplearning.ai - Stanford University
It allowed me to know the applications of artificial intelligence in different problems.
Bachelor of Applied Mathematics & Computer Scienc
2013 - 2019
National Autonomous University of Mexico (UNAM)
Where I studied my degree and where I was able to learn about the world of artificial intelligence and part of the basic mathematics with which it works

Relational Graph Neural Networks for Fraud Detection in a Super-App environment
Large digital platforms create environments where different types of user interactions are captured, these relationships offer a novel source of information for fraud detection problems. In this paper we propose a framework of relational graph convolutional networks methods for fraudulent behaviour prevention in the financial services of a Super-App.
Feature Store, limitation of AI models?, Theory of a Feature Store
From experience working, I have discovered that the main problem when implementing machine learning models is having the features, data points or whatever you want to call it
