About

Hi, my name is Jose Alberto Ramos. I'm passionate about artificial intelligence and currently i'm working at Rappi. I enjoy my free time being a full stack developer, a hobby that has become one of my favorites

I'm Machine Learning Engineer & Data Scientist in Rappi

We use technology to meet business requirements, my main focus is on fraud, developing machine learning models for transactional fraud and the implementation of onboarding fraud models.

I am originally from the state of Puebla, but I have been living in the CDMX since 2012, I did the Bachelor of Applied Mathematics and Computer Science at the National Autonomous University of Mexico (UNAM)

In 2021 the University awards me the Gustavo Baz Prada medal, it is awarded to the best social service of the generation, I carried out a project for the Mexican Economy Secretary which gave me said award

Hobbies

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
Python 90%
Angular 80%
React 75%
Go 70%
Ionic 60%
Docker 90%

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

Resume

I have a bachelor's degree in applied mathematics and computer science. As a hobby I take courses on artificial intelligence as well as a fan of reading medium articles.

Sumary

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

Articles

At work we have research teams, we collaborate with each other to generate experiments and research, we also do medium posts.

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
