</> Development
We’re Sarah and Alex Eyer — two developers with a passion for building clean, functional apps and websites. This is our shared portfolio, featuring the projects we’ve created using tools like Swift, Kotlin, Android Studio, Xcode, and more. From concept to code, it’s a snapshot of our journey as coders — lots of learning, late nights, and a love for creating things that work.
Website Development
We build responsive, user-friendly websites using HTML, CSS, JavaScript, PHP, and SQL — often combining custom code with platforms like WordPress. From simple content pages to dynamic web apps, every project is structured for performance, accessibility, and scalability.
Wyrmhole Innovations
Our tech services and development business site. Includes details on IT support, app and web development, hosting, and blog content. Built with Divi and fully responsive.
The Reef Vault
An e-commerce site for a coral and saltwater fish store in Magnolia, TX. Built using WordPress and WooCommerce with a custom design, responsive layout, and SEO optimization.
The Tiny Branch
A blog and shop focused on nature-inspired living and handmade goods. Custom Divi design with blog, store, and newsletter integration. This site is still in development.
J Tire LLC
A mobile-first website for a tire shop under new management. Designed for strong local SEO, service visibility, and ease of use. This tire shop is in Excelsior Springs, MO.
Mentoring & Counseling Center
A clean and calming WordPress site for a professional counseling practice in Magnolia, Texas. Thoughtfully organized for accessibility and client outreach.
Phoenix Volunteer Fire Department
A responsive, info-rich website for a local fire department in Hollidaysburg, PA. Designed to share updates, events, and volunteer opportunities.
Native App Projects - iOS & Android
All of our apps are built from scratch in Android Studio or Xcode using Java, Kotlin, and Swift. We design custom UIs, integrate third-party APIs, and develop backend features like authentication, database syncing, and real-time updates — depending on the project’s needs.
Persistent Memory
An iOS memory matching game built using Swift and UIKit, featuring adaptive layouts for iPhone and iPad with dynamic grid sizes based on device. Upon completion, user performance data is saved using Core Data and displayed in a high scores view. We used view controller state management, local data persistence, size class-based UI changes, and building structured, replayable game logic.
RESTful API & JSON in UIKit
An iOS app built using Swift and UIKit to fetch and display congressional data from the ProPublica API. It features API key authorization via headers, JSON parsing, dynamic TableViews, image loading using member IDs, and detail views with full legislator profiles. This project strengthened my skills in RESTful API integration, working with JSON, and managing asynchronous UI updates.
Reddit API Viewer
An iOS app built with Swift and UIKit that lets users browse subreddit posts in a clean, sectioned table view. It uses Reddit’s public JSON API to fetch posts dynamically and allows users to save their favorite subreddits. The interface is fully customizable using RGB sliders, and user preferences (including colors and subreddit choices) are stored using UserDefaults.
🤖 Silver Coin Melt Calculator
An Android app that calculates the real-time melt value of U.S. silver coins based on current spot prices. Built with custom logic and coin data, this app allows users to input various coin types and quantities to calculate total silver value. This project strengthened my skills in math modeling, working with real-time data, and designing user-focused utility apps.
🤖 Birth Setting Risk Calculator
An Android app developed in collaboration with Dr. Maribelle Gross to turn peer-reviewed medical research into an interactive decision-making tool. We implemented the logic, math models, and user interface based on the original journal’s methodology. This project strengthened our skills in collaborating across disciplines, translating complex research into code, and building purpose-driven apps that support real-life decisions.
🤖 CRH Collectors Log
Coin Roll Hunting Tracker is a lightweight Android app that helps coin collectors keep track of what they find when hunting rolls of coins. Users can log how many wheat pennies, silver nickels, foreign coins, or other special finds they get in each box. The app saves the totals so users can compare boxes over time and see how successful their hunts have been.
