LOS ANGELES CAPITAL Los Angeles, CA

Applied Finance Project (Master Thesis): “Text Based Signals using NLP” July 2019 - December 2019

• Researched an Alpha opportunity by identifying a novel source of text data

• Utilized Natural Language Processing to target and evaluate the customer’s sentiment towards products listed on Amazon for small-to-mid sized firms.

• Explored how different sentiment techniques (Bag-of-words, Polarity function) compare to each other in terms of effectiveness based on their accuracy

MOTOR OIL HELLAS Athens, Greece

Data Scientist Intern June 2019 - September 2019

• Built an ETL pipeline to store the data related to clients’ payments and defaults provided from the subsidiary companies (SSIS, SQL Server)

• Developed a machine learning model to assess client creditworthiness

• Translated the business problem into a methodological problem, in which we want to estimate the probability of default for each client. Trained a Logistic Regression using historical data of the prior clients along with macro- economic factors and performed cross-validation to assess the performance of the model and achieved 0.87 accuracy.

• Automated procedures using VBA and Excel which assisted in preparing the company’s quarterly report 10-Q BLOODE (Online blood donor registry, nonprofit Startup) Athens, Greece Founding Member April 2016 - May 2018

Event Coordination & Management

• Initiated corporate and government collaborations resulting in $30,000 sponsorships and donations

• Coordinated public and private events for groups of 50 to 1000 people to promote blood donor awareness

• Managed company growth of the company from 3 to 20 staff members; recruited, trained and supervised 15 volunteers

RELEVANT PROJECTS

• Created an Artificial Neural Network to solve a Customer Churn problem

- Used a sample of 10,000 customers of a bank and their personal credit data to create a demographic centric model which predicts which of the customers are at highest risk of leaving the bank (0.8625 Accuracy of Model)

• Implemented a Recurrent Neural Network to predict Stock Prices

- Trained a stacked LSTM model on five years of Google’s stock price (2012-2016) and successfully predicted the upward and downward trends of the future stock price.

• Experimented with Boltzmann Machines and Autoencoders to create a Recommendation System

- Built two recommendation systems, one Boltzmann Machine, to predict whether a user will like or not a specific movie based on previous ratings on a number of movies and achieved an accuracy 0.75 and one Stacked Auto- Encoder which tries to predict the rating (1-5) of a movie by a user.
