Projects

SENTIMENT ANALYSIS ON IMDB DATA – Personal Project – Seaside, CA - April 2023

● Utilized Python to perform EDA on the dataset.

● Utilized Python and Scikit-Learn to perform sentiment analysis on 50,000 movie reviews.

● Performed data cleaning and split each review and sentiment into training and test data.

● Applied regression and machine learning to produce a final model. ANOMALY DETECTION OF LARGE AMOUNTS OF DATA – Work Project – Pearl Harbor, HI

- May 2021

● Used a large shipping database and used Python and Machine Learning algorithms (Scikit-Learn, Keras, and Tensorflow),

● Ran as a batch overnight,

● Sharded the results in numerous sectors of then a shared directory (pre-cloud for the client).

● Aggregated and visualized the data by using pandas, matplotlib and wordcloud to compile a professional report.

● Briefed results to operational leaders for decision-making. Work Experience

DATA ANALYST – USGI – Seaside, CA October 2022- April 2023 I used Excel, R programming, and Python programming to sort through big data and to conduct ETL, using R Studio and Jupyterlab via Anaconda on a classified system as well as using them on an unclassified home system. I am using Microsoft SQL Server but have also used SQL Lite and MySQL.

Used Excel, dplyr in R and pandas in Python for data manipulation, and the ggplot2 package in R-Studio to create visualizations in R, and dashboards in Tableau, Power BI, and Excel. I also use Matplotlib and Seaborne in Python DATA ENGINEER – Calhoun International, LLC – Honolulu, HI January 2021 - September 2022 I used Python and SQL. Using Python, I've used Word2Vec, Doc2Vec, Scikit-Learn, Keras and Tensorflow to write Machine Learning and Sentiment Analysis programs including Anomaly Detection of outliers relating to a large dataset briefing the results to operational decision makers.
