Dear Sir/Ma’am,

As a student of Data Science in University of Arizona, I worked on data collection, data preparation (data cleaning, missing value treatment, etc.) and organizing data into usable formats, statistical data analysis in Python, feature engineering, model training, and model selection with various supervised and unsupervised machine-learning models (including Clustering, time series analysis, anomaly detection) in Python using various Python libraries like Pandas, scikit-learn, PySpark, Keras, SpaCy, NLTK, etc. I also worked on R programming language, data visualization in Tableau, querying on structured and unstructured data in SQL and NoSQL respectively, Apache Spark, Hive, MapReduce, MongoDB, Deep Learning tools like Tensorflow and Generative AI modeling using Natural Language Processing, Named Entity Recognition, etc. I am also an expert in AutoCAD and various MS Office tools. I have good knowledge of cloud services like AWS and Azure, version control systems like Git and project management tools like Jira and Scrum.

I demonstrated my communication skills, presentation skills, my ability to work in a team as well as independently and my MS Office expertise including Excel VBA in my previous role as an engineer in department of Tendering and Business Development in Larsen & Toubro Ltd. Mentoring new joiners also was my responsibility. I am very fluent in English, have intermediate skills (B1) in German. I am able to convey my ideas clearly. 

Having extensively researched your company’s values and products, I feel it would be the ideal place for me to develop my career and I believe that I can be an excellent addition to your team. I look forward to discussing the position and my qualifications with you in more detail.

Thank you so much for your time and consideration.

Yours sincerely 

Saumia Ria Varghese
