Sessions / Jobs
For every 15 minutes
With more than a decade of experience, I have been involved in different aspects of Data Analytics and Enterprise Software applied to domains such as Life Sciences, Ambient Sensing, and Real-time Simulators. I am available for consulting (off-line) data science jobs, including effective data visualisations, statistical inference, prediction, classification, results communication and report. I regularly use R, Apache Spark, and cloud resources if needed.
- 6 years experience
I came to R by chance, while working in a bioinformatics institute. There, we had to provide tools for researchers to deal with biological data. I have to confess that at first I didn't like it. Being a software engineer I prefer languages that allow you to build and scale complex software systems. R is not meant to be that way. The language is build for statistics and data analysis work, and has probably the richest ecosystem for that purpose. In the end I loved to work in RStudio and using DataFrames, ggplot2, and build all sort of machine learning models with just a few lines of code. Very powerful tool that you can now even combine with Apache Spark!

I came to machine learning and data analysis from a Software Engineering background. I have a PhD in real-time distributed systems and my interest is to build data products that give companies the edge. I am particularly interested in building data products that can scale to large amounts of data and work in real-time.

A fundamental part of data analysis, machine learning, and research, is being able to do statistical inference and understand the mathematics behind the computations. Coming from a computer programming background, I had to apply myself intensively in order to understand why and how to use the methods in the data scientist toolbox.

Building a Movie Recommendation Service with Apache Spark & Flask - Part 2
This Apache Spark tutorial goes into detail on how to use Spark machine learning models, or even another kind of data analytics objects, within a web service. By using the Python language, we make this task very easy, thanks to Spark own Python capabilities and to Python-based frameworks such as Flask.
Data Science with Python & R: Dimensionality Reduction and Clustering
An important step in data analysis is data exploration and representation. In this tutorial we will see how by combining a technique called Principal Component Analysis (PCA) together with Cluster, we can represent in a two-dimensional space data defined in a higher dimensional one while, at the same time, be able to group this data in similar groups or clusters and find hidden relationships in our data.

Jose is an expert when it comes to programming in R and Latex. He knows the high-level programming in R and Latex and is good at making understandable explanations to each code. His report is clear but with detailed explanation to each step supporting by clear and beautiful tables and plots. The report structure also arranges in a very efficient and professional way. I would highly recommend him to anyone based on his good writing and formatting style.

I'm extremely pleased with all the work Jose has helped me with. Not only is he a great coder, he is also an excellent communicator who explains his work very clearly. He also maintained active dialogue with me throughout the entire project to ensure that he included everything I needed. I highly recommend him for both mentor sessions and freelance work!
