Marriott Homes and Villas Case Study: This project gave me the chance to apply my coding skills in a real-world context while working through a streamlined product development process. I gained experience beyond just front-end development by diving into user research, thinking through product decisions, and seeing how engineering, design, and product management come together to build digital solutions. It deepened my understanding of how collaborative, user-centered digital products are made.

Random Show Generator: This project involved building a feature that suggests random shows based on user input. I worked within a pre-existing codebase, writing JavaScript functions that responded to dropdown selections and dynamically updated the page content. Users could filter by genre or choose an entirely random option. This project helped me sharpen my skills in conditional logic, event handling, and DOM manipulation, while also giving me a better sense of how interactive features can improve user experience.

Search & Filter Prototype: In this project, I built a functional prototype for a search and filter feature inspired by Airbnb’s user interface. I implemented JavaScript functions to filter listings based on city, price range, and type of place using arrays, conditionals, and nested loops. This project helped me gain confidence in writing modular code and reinforced the power of simple logic to drive dynamic user experiences. It was a key step in learning how to make web apps more responsive and user-friendly.

Mad Lib Madness

For this project, I created a Mad Libs–style game that lets players input random words to generate funny, dynamic stories. It was a fun way to put my JavaScript skills into practice, especially working with strings, variables, and user input. I focused on building a smooth, interactive experience while reinforcing core concepts like DOM manipulation and string interpolation. This project gave me a creative outlet to apply what I’d learned in a playful and engaging way.

"Studdy Buddy" Mind-Map

This mind map outlines the core functions and design principles behind “Studdy Buddy,” a conceptual productivity app for students. It explores user needs, key features, and potential interface flows in a visually organized format.

App Icons (sketches)

These hand-drawn app icon sketches were part of a graphic communications assignment focused on visual storytelling. The designs explore shape, symbolism, and clarity to represent core app functions at a glance.

LabelLord 2.3 (labeling robot)

LabelLord 2.3 is a labeling robot I designed and built using TinkerCAD as part of a collaborative engineering project. Working with my team, we identified a real-world packaging problem and developed a system of automated robots to solve it. This robot was my individual contribution to the system, featuring a servo-based labeling mechanism and sensor-triggered automation.

Electronic Circuit (simulation)

This TinkerCAD simulation showcases the electronic circuit and Arduino code I developed for LabelLord 2.3. The circuit integrates ultrasonic and IR sensors with a servo motor to create a responsive labeling system. I wrote the control logic in Arduino, enabling automated package detection and label application.
