PROJECTS

MORTGAGE DEFAULT MODEL

This real-life large project consists of five different sub-projects.

- Downloaded and sampled 15 million rows of mortgage performance data from Freddie Mac using AWS - S3, AWS - Athena and SQL.

- After understanding the content of the dataset which has 557,000 samples, necessary cleaning and adjustments were performed by using python. After imputation the missing values, required scaling and encoding were applied. Hyper-tuning was carried out through grid search and pipeline methodologies, using Logistic Regression and XGB Classifier algorithms.

- After enriching the dataset, the newly obtained results were compared with the previous scores. ROC and F1 scores were interpreted.

- In the explainability part, the impact of all features on predictions was observed and interpreted.

TWITTER SENTIMENT ANALYSIS

Designed and implemented a software system to investigate the role of social media in instilling anti- American sentiment among US allies through misinformation and disinformation efforts. The project encompassed data collection, data handling, machine learning and insight generation.

SPAM DETECTION

It is a public set of comments collected for spam research. It has five datasets composed by 1,956 real messages extracted from five videos that were among the 10 most viewed on the collection period. The project encompassed bag of words, stopwords, min_df, max_df, n_grams, evaluation of feature importance, machine learning and insight generation.

WORK EXPERIENCE

Data Science Intern, DECI TECH

Working as an intern delivering data science projects to clients in the finance industry.

As a Data Science Intern at DECI TECH. My responsibilities included leveraging statistical analysis and machine learning techniques to extract valuable insights from large datasets. I actively participated in the end-to-end process of project development, from data collection and preprocessing to model training and deployment.

I collaborated closely with cross-functional teams to understand client requirements and design solutions that addressed their business challenges. This experience allowed me to apply my knowledge of programming languages such as Python and SQL, as well as proficiency in data manipulation and visualization tools like Pandas, NumPy, and Matplotlib. I also debugged an information leakage bug, which caused a misunderstanding of the model.

Moreover, I gained hands-on experience in developing predictive models, conducting exploratory data analysis, and implementing data-driven strategies to enhance decision-making processes for our clients

Overall, my time as a Data Science Intern at DECI TECH provided me with valuable insights into real-world applications of data science in the finance industry, and I further developed my skills in problem-solving, data analysis, and project management."
