I architected 2135: Resource Crisis, a choose-your-own-adventure-style mobile application that merges interactive storytelling with the structural rigor of modern enterprise applications. Unlike traditional games, I built it from the ground up without a game engine, using scalable, modular components commonly found in serious business apps.

This cross-platform app serves as a narrative delivery framework, demonstrating best practices in modular architecture, client-server API design, offline-first data sync, secure authentication, and modern Android/iOS UI using Jetpack Compose and SwiftUI.

The application showcases my expertise in full-stack system design, UI/UX flow, media integration, and DevOps. It is currently deployed via AWS with releases managed through TestFlight and Google Play Console, and it demonstrates reusable patterns for B2C, educational, and media-based applications.

This project serves as both a technical portfolio and a creative product, highlighting how meaningful UX can coexist with enterprise-grade engineering to create impactful and meaningful experiences.

The beta release is expected in May 2025. You can join the public test via tester sign-up: https://forms.gle/gViQh4MqQANKg1dj8.

I built an automotive client app that allows users to record video in various modes for upload to a server, where it is used for machine learning (ML) model training. The app also supports video streaming to the server, where it is evaluated against the ML model. Once the evaluation is complete, the application sends an alert to the mechanic's or worker's watch device, notifying them of any potential issues.

This project served as a proof of concept for the client, demonstrating the technology's value and justifying further investment. The successful implementation led to an extension of the consulting contract and the team's expansion.

I was part of a team building a custom in-house application using native iOS Swift. The project served as a demonstration of our technical skills and the platform's capabilities. I contributed to developing standard business application features, including localization, a splash screen, audio integration, API usage, local database support, and multiple styling options for customization.

The application was designed to align with its counterparts on Android and Flutter (cross-platform), ensuring a consistent look, feel, and feature set across platforms. I actively supported this crossover effort, enabling smoother collaboration and team integration.

I remained on the team for several months, working on many features. After contributing significantly to the application's development and cross-platform consistency, I concluded my involvement.

I developed and launched a fully functional Android application to the Google Play Store, implementing client-driven business logic features tailored to specific user needs. I engineered a user data-driven recommendation algorithm using Android Java, with SQL connectivity through a PHP-based server powered by MySQL.

I deployed the PHP back end to a self-managed server via SFTP and released the Android app to the Play Store. Following the launch, I maintained continuous development for nine months, delivering regular updates and ensuring user satisfaction through consistent improvements and support.

A veterinarian website for end-of-life care for pets as an at-home service. Worked with the client to achieve a professional site that will drive customers. The website has been successful as customers have found it searchable and simple to use and understand, and have contacted us to schedule appointments for care.

Additionally, designed the logo, built the site by hand via HTML, CSS, and JavaScript, and prepared images for professional use. The client has already contacted me about building a larger website in the future when her practice is in place.

A vehicle inspection Android application for critical business use at the company. Qualified service members used AiM Inspect in its various forms to guide the inspection process of vehicles for auctions, company sales, or leases. With a leading auction house as primary investor and many contracts with major corporate auto financing and dealerships, the application was used by thousands of users across the country daily on Zebra and Samsung devices.

The app would function via user sign-in and then check the version numbers of local DBs. If they failed this check (outdated or non-existent), the data would be downloaded from the AWS S3 bucket and delivered to the device. Some areas did not have internet connection, so it was critical to enable work to be performed "offline" with ways of updating the inspections if there was missing critical data. The application had a complex algorithm to calculate costs to damages and had an expansive UI to be able to have detailed inspections on all parts of the car, including images of the condition.

As a lead engineer, I enforced quality control on coding standards and ensured logic safety coverage via integration and local mocked tests. I also planned and led the team in large efforts.
