C# Console Application – Vowel Counter

This C# console application demonstrates fundamental programming concepts including user input, string manipulation, and method design. The program prompts the user to enter a phrase, then processes the input to count the number of vowels using iteration and conditional logic. A dedicated method encapsulates the counting logic, improving code organization and reusability. The implementation highlights clean structure, readability, and effective use of built-in string functions. This project showcases foundational problem-solving skills and an understanding of core programming principles in a strongly typed language.

Responsive Website Development – Mobile Panini Homepage

This project showcases front-end web development skills through the creation of a responsive homepage for a fictional food business. Built with HTML5 and CSS3, the page includes structured semantic elements, navigation menus, images, and contact information. The design emphasizes usability, accessibility, and clean layout practices while adhering to modern web standards. External stylesheets are used to separate content from presentation, improving maintainability and scalability. This deliverable highlights the ability to build visually appealing and functional web interfaces with a focus on user experience and organized code structure.

Python Data Analysis – Linear Regression Modeling

This project applies Python to perform data analysis and predictive modeling using real-world car data. Multiple linear regression models are developed to evaluate how variables such as mileage, engine displacement, top speed, and maintenance interval influence vehicle price. The program utilizes libraries like pandas, matplotlib, and SciPy to process data, visualize relationships, and calculate statistical metrics including R² and p-values. It also generates predictions and interprets results to identify the strongest predictors. This work demonstrates proficiency in data analysis, statistical reasoning, and Python-based scientific computing.
