Senior data scientist with strong data engineering and software development background. Electronics engineer with a Masters in IT
I'm experienced in data data scientist with a strong experience in software development and data engineering. I've have a strong experience applying data engineering and ML techniques to detection of security incidents, fraud, scam and evaluating risk. In addition to my data science experience I have more than 5 years of experience in cyber security world where I have to evaluate risk, detect and manage fraud and cyber incidents. I've created communities in Facebook to teach programming and datascience and IT aiming to help people to transition a carer in Dev or data. I love creating products and buildings I love learning about diverse topics, this gives me and edge when understanding data coming from different domains. My qualifications are: Electronics engineer and Masters of IT.

Fertilizer prediction system using ML
Sep `21 - May `22
8 months
Agrosavia (The research and tech arm of the Colombian ministry of Agriculture )
This project involved creating a prediction system to process soil lab samples from farms. The system currently helps the Agricultural engineers to manage the process of providing an adequate set of fertilizers and their quantity for a specific crop for thousands of farms in Colombia every month. The system reduced the engineer's manual work by using AI to make a prediction of the result which had to be reviewed before approval. Data: Soil lab analysis for the nutrients (levels of Nitrogen, calcium, magnesium ) and the set of fertilizers recommended by an agricultural engineer. The model: A gradient boosted regressor, it was deployed in docker (as a micro-service) using Kubernetes I coded and trained a machine learning model to predict and deployed it as a micro service in the Kubernetes cluster
Responsibilities & achievements
Analise the data Lead the team of developers, fix bugs, design and train machine learning models. Deploy microservices using fastAPI. Test model performance and accuracy
Monitoring system for power lines in remote areas in Colombia
