Strongbytes | Jun 2020 - Oct 2020

Data Scientist

Worked on a 2-month project where I initially had to ingest, clean and process data. Afterward, I extracted relevant statistics, applied several machine learning algorithms and presented the results in a Power BI App. Afterward, I was responsible for the maintenance and deployment of machine learning models with Azure, as well as building and presenting reports with Power BI.

Strongbytes | Dec 2019 - Mar 2020

Machine Learning Intern

The training part of the internship was focused on exploratory data analysis and feature evaluation of the “House Prices” dataset from Kaggle with Python’s main machine learning libraries: Scikit-learn, Pandas, Seaborn and LightGBM. Our team applied this knowledge to predict the production of wind energy in Romania, integrating energy data from ENTSOE and weather updates from Dark Sky. We also deployed the model with Azure for potential public usage.

Pentalog | Feb 2020 - Feb 2020

Web Development Training

With the help of great mentors, I had the opportunity to attend a 2-week web development crash-course. The first project I completed was a CV-template where I learned how to use the grid and flexbox layout. Afterward, I got introduced to JavaScript and did basic DOM manipulations with it.

Amazon | Jul 2017 - Sep 2017

Business Intelligence Intern

Worked for the WebAnalytics team where I created a model to analyse and categorise customer behaviour. This offered my team insight into past and future usage patterns and improved the understanding of their users. I used MySQL to query the database, Excel and Tableau for analysis and visualization.
