What this demonstrates
More than a calculator.
This portfolio project demonstrates practical web application development by combining clean interfaces, functional JavaScript logic, validation, accessibility considerations, and responsive design.
Application Logic
JavaScript-powered arithmetic operations, operator handling, decimal validation, and error handling.
Responsive Design
The application adapts to desktop, tablet, and mobile screen sizes while maintaining usability and accessibility.
Technology
Built with modern web technologies.
A lightweight front-end architecture keeps the application fast, maintainable, and easy to extend.

Project Breakdown
Designed like a real application.
Clean Architecture
Separate interface,
application logic,
and reusable functions.
Input Validation
Prevents invalid decimal
input and handles unexpected
calculations.
Keyboard Support
Users can operate the calculator
using their keyboard as well as
the on-screen interface.
Mobile Ready
Responsive layout optimized for
smaller displays and touch
interaction.
Expandable Design
The architecture can be extended
with history, scientific functions,
themes, or database integration.
