This repository contains the hands-on projects I developed as part of the IBM Data Science Professional Certificate on Coursera. The specialization provides a comprehensive foundation in data science, from data analysis to machine learning.

From Course 5. In this project, I used Python to scrape and visualize stock data, aiming to create an interactive dashboard.
Tools: pandas, requests, bs4, html5lib, lxml, plotly, yfinance

From Course 6. Created and populated a relational database using IBM Db2 SQL, then analyzed Chicago city data using Python.
Tools: IBM Db2, SQL, Jupyter Notebooks, CSVs

From Course 7. Built regression models to predict housing prices based on property features.
Tools: pandas, numpy, matplotlib, seaborn, scikit-learn

From Course 8. Built a flight performance dashboard using alternative tools due to technical limitations with IBM’s internal platform.
Tools: jupyter_dash, plotly, Google Colab

From Course 9. Compared several classification algorithms on a loan dataset to identify the best-performing model.
Tools: Logistic Regression, SVM, Decision Tree, KNN

The final capstone: predicting the success of SpaceX launches.
Steps involved:

• Data collection via SpaceX API and Wikipedia
• Data wrangling and visualization (SQL, Plotly, Folium)
• Feature engineering + One-hot encoding
• ML with GridSearchCV to optimize model parameters
• Models: Logistic Regression, SVM, Decision Tree, KNN
  Accuracy: ~83.33% across all models

This was my favorite and most challenging project – the real kickstart to my data science journey.
Greatness in small beginnings.
