Breakthrough is a media agency that has a lot of their
content in social media platforms. I was hire to build
a daily data gathering system of that content from
different social media platforms.
1. Google app engine application built using python that
captures data using different API connections and stores it on
a MySQL database and NoSql.
2. Web application developed in django to classify sentiments
on tweets and Facebook comments with the aim of building
training sets for machine learning models.
3. Natural language process model built in python and spark to
analysis semantics on tweets and Facebook comments.
4. Natural language process model to perform sentiment analysis
utilizing neural networks.
5. D3.JS dashboard with PPC performance indicators and traffics
estimations
Technologies used: Python(scikit-learn, pandas),
R, SQL, Spark

Data Scientist at Hitachi Consulting
  • United Kingdom
  • November 2014 to July 2016

I was hired by Hitachi to collaborate on the
development of a proof of concept that involves
building a prioritisation system for containers
that arrive at a port.
1. Supervised learning approach making use of python sci-kit
learn to train and test support vector machines
2. Semi-supervised learning approach with support vector
machines developed in R
3. D3.js dashboards to visualise models recommendations
Technologies used: Python(scikit-learn, pandas),
R, SQL, SQL, D3.JS

Data Scientist
  • United Kingdom
  • June 2015 to November 2015

My duties at Microsoft were to build an automated
system that can classify and analyse both text and
images on a gamers feedback platform. I also
involved on Microsoft Paint telemetry system.
1. C# Natural Language processing max entropy approach to
approve or reject user's feedback regarding its content.
2. Developing and training a support vector machine
to perform sentiment analysis on user's
feedbacks. This task was accomplish with python
pandas and scikit-learn
3. Usage of Speeded up Robust Features algorithm and
a support vector machine to detect and classify
bugs during gameplay on screen shots.
4. Usage of map and reduce jobs, SQL queries to extract and
transform data on Azure to later be presented in a PowerBi
dashboard.
Technologies used: C#, Java, R, Python, Excel and SQL,
Hive.

Data Scientist at IG
  • United Kingdom
  • June 2015 to November 2015

I was hired by IG to devise and implement attribution
models across multiple channels. I was responsible for
the mathematical modelling and implementation of this
project. As IG Data Scientist my main responsibilities
where:
1. The first phase revolved around collecting
cookie level noisy data and creating a SQL clean
database with clusters.
2. The second phase focused primarily on using machine
learning, Bayesian network and Markov chain methods implemented
in Java to
model the channels and their dimensions
3. The final phase used Markov decision processes and genetic
algorithms to processes and genetic algorithms to optimize the
channel spend to maximize the profit of the advertising
campaign. This was accomplish using JAVA.
4. The next step was to build a simple Hadoop cluster to
implement and train the machine learning models making use of
map-reduce jobs.
Technologies used: Java, R, Python,
Excel, Hadoop, Map reduce, Pig.
