Motivated and detail-oriented university graduate with a background in healthcare and data analysis, offering 32 months of clinical experience as a Junior Dentist and hands-on experience as a Data Analyst intern. Actively seeking a full-time position as a Clinical Data Analyst/Healthcare Data Analyst. Excited to leverage my analytical skills, healthcare expertise, and data science experience to support data-driven initiatives, contributing to improved patient outcomes and operational efficiency. Open to continuous learning and committed to adding value to the organization and advancing my professional development in healthcare data analytics.

1) HEART DISEASE PREDICTION USING MACHINE LEARNING

Role: Data Scientist
Duration: Three months
Technologies Used: Python, Scikit-learn, Keras

• Conducted comprehensive analysis of heart disease patient dataset, involving data cleaning, preprocessing, and feature engineering.
• Developed and trained multiple machine learning models including Logistic Regression, Naive Bayes, SVM, K-Nearest Neighbors, Decision Tree, Random Forest, XGBoost, and an Artificial Neural Network.
• Achieved highest model accuracy of 95% with Random Forest, and conducted thorough model evaluation using various performance metrics.
• Utilized Python libraries such as pandas for data manipulation, matplotlib and seaborn for visualization, and scikit-learn and Keras for implementing machine learning algorithms.
  

2) ANALYZE DEATH AGE DIFFERENCE OF RIGHT-HANDERS WITH LEFT-HANDERS

Role: Data Analyst
Duration: One month
Technologies Used: Python, pandas, matplotlib, numpy

• Analyzed age distribution data to investigate the reported early death of left-handed people compared to right-handers.
• Applied Bayesian statistics and data visualization techniques using matplotlib to create detailed visualizations.
• Used Bayes' theorem to calculate the probability of dying at a certain age given handedness, comparing left- and right-handers.
• Found that changing rates of left-handedness over time significantly affect the apparent mean age of death, challenging the claim of early death for left-handers.

3) ANALYZE AND VISUALIZE STUDENT HEALTH DATA

Role: Data Analyst & SAS Programmer

Duration: Six weeks

Technologies Used: SAS, Excel

Data Preprocessing: 

• Imported and merged student weight and height data from STAT and HIST classes.
• Converted data to metric units and calculated BMI.
• Classified students into health status categories based on BMI.

Visualization:

• Generated a pie chart to visualize health status distribution.

Frequency Distribution Report:

• Created a frequency distribution table for gender and health status.
• Formatted count and percentage values as xx (yy.yy%).
• Transposed the dataset to display health status.

SAS Macro Development:

• Developed a macro (myStat) to automate the frequency distribution table generation.
• Included input parameters for flexible table generation.
• Successfully generated reports using the macro.

4) DATA VISUALIZATION OF BIRD STRIKES BETWEEN 2000 - 2011

Role: Data Analyst

Duration: Six weeks

Technologies Used: Python, Tableau

• Analyzed bird strike data from FAA (2000-2011) to identify patterns and trends, focusing on the number of incidents, affected airlines, and airports.
• Created detailed visualizations using Python, Tableau to depict yearly bird strikes, timing, altitude, and phases of flight during incidents.
• Investigated the impact of bird strikes on flights, including cost analysis and effectiveness of pilot warnings, utilizing data processing and visualization techniques.
• Developed interactive dashboards in Tableau and ensured code quality with best practices for modularity, safety, testability, maintainability, and portability.
