Programming Examples
Javascript Calculator
How it works:
Uses HTML for the interface (buttons for numbers and operations, display area).
JavaScript listens for button clicks (event listeners), then updates the display and stores inputs.
When an operation is triggered (like addition or multiplication), the script calculates the result using JavaScript logic and variables, then updates the display in real time.
Includes error handling, like preventing divide-by-zero or invalid input sequences.
Dynamic and interactive, showing DOM manipulation, conditional logic, and state management.
This project demonstrates my ability to write functional, interactive JavaScript applications. The calculator handles user input, performs arithmetic operations, and updates the display dynamically, showcasing my skills in DOM manipulation, event handling, and logical programming.
Form Demo w/ JQuery Validation
How it works:
Uses HTML form elements for user input (text fields, dropdowns, checkboxes, etc.).
jQuery Validator plugin runs when the user submits the form, checking each field against rules (required fields, email format, number ranges, etc.).
If a field fails validation, the script shows a clear error message next to it, guiding the user to correct it.
Only when all inputs are valid does the form submit, ensuring clean, accurate data.
Progressive enhancement: If JavaScript is disabled, the form still functions, though without validation prompts, maintaining accessibility.
This project demonstrates my ability to create interactive, user-friendly forms using jQuery. The form includes input validation that checks for required fields, correct formats, and user-friendly error messages. It highlights my skills in JavaScript/jQuery logic, enhancing UX, and ensuring data integrity—all essential for web applications that collect user input.
Database Examples
Advanced Spreadsheet Analysis
This example demonstrates my ability to analyze and interpret sales data using spreadsheet tools. I worked with a dataset of product categories, units sold, total sales, and sales rank to generate insights that help guide business decisions.
Key takeaways and techniques demonstrated:
Sorting and ranking: Identified top-selling categories like Condiments and Beverages.
Formulas for calculations: Used SUM, AVERAGE, and basic arithmetic to determine total sales and unit performance.
Conditional formatting & visualization: Highlighted high- and low-performing categories to quickly spot trends.
Data-driven insights: Recognized that some categories had zero sales, prompting recommendations for inventory adjustments or marketing focus.
This project shows my analytical skills, attention to detail, and ability to turn raw data into actionable insights, essential for both business and technical roles.
Inventory & Sales Analysis for Jewelry Store
This project demonstrates my ability to analyze product inventory and financial data for a retail environment. I worked with a detailed spreadsheet of jewelry items categorized by metal type (Gold, Silver) and product type (Bracelets, Earrings), including stock counts, total value, and pricing information.
Key takeaways and techniques demonstrated:
Inventory insights: Identified high- and low-stock items to help prioritize restocking and sales focus. For example, Gold Bracelets had the highest quantity, while Silver Earrings had no stock.
Financial analysis: Calculated total value and average price per category to assess profitability and pricing strategy.
Data organization & formulas: Used SUM, AVERAGE, MIN, MAX, and COUNT to extract meaningful metrics from raw data.
Decision-making support: Findings could inform purchasing decisions, marketing campaigns, and sales promotions to maximize revenue.
This example showcases my ability to synthesize large datasets, uncover trends, and present actionable insights, skills that are crucial for roles involving database management, analytics, and business strategy.
