I build seamless digital and physical experiences—melding iOS, IoT, and automation to craft intuitive, intelligent systems.
A maker at heart, I bring together technology to create solutions that add value, ease, and joy to life.
This page is dedicated to showcasing some of my most exciting contributions as a software developer. Over the past 6+ years, I’ve had the privilege of working with great companies, mentors, and peers, developing iOS applications across various industries—particularly within the Internet of Things.
My curiosity about how things work has always driven me. Every question leads to exploration, every exploration leads to learning, and I continuously apply these insights to my work and life.
I specialize in native iOS development, seamlessly integrating third-party APIs to craft powerful applications for Apple devices. I’ve collaborated with large teams on apps used by millions, developed a clinical trials app while working directly with executives, and built creative personal projects that merge software and hardware.
At Cue Health, I was recognized as a Subject Matter Expert in iOS and Android within just six months. At Ford Motor Company, I contributed to the main app and prototype app for the Ford Mustang Mach-E Electric, helped interview and train new candidates, and led cross-platform testing demo teams.
I’m always looking to connect with people who take a multidisciplinary, critical-thinking approach to problem-solving. If that sounds like you, let’s talk!

Cue Health App
Most recently, I served as an iOS Product Developer, Subject Matter Expert, and Document Approver for FDA Submissions at Cue Health, Inc., a leading biomedical company at the forefront of COVID-19 testing and virtual healthcare.
I contributed to the development of the flagship Cue Health app, where I was quickly promoted to manage the Clinical Trial project, a mission-critical initiative for the company. In this role, I collaborated closely with firmware engineers, doctors, designers, testers, and product managers to develop iOS code used by real clinical trial participants. The results of these trials were pivotal in securing FDA approvals for expanding Cue’s test offerings.
Due to the high-stakes nature of this project, I worked directly with Cue’s Chief Medical Officer and other top executives, ensuring the app met rigorous standards for medical accuracy and compliance.
Additionally, I played a key role in onboarding new hires, training them on the development process, and authoring and maintaining resource documents critical for internal knowledge sharing and project success.

Lincolnway App
During my time at Ford Motor Company, I worked as an iOS Developer contributing to the LincolnWay® app, the premium vehicle connectivity platform for Lincoln’s luxury vehicles.
I was responsible for developing and enhancing innovative features, including the Phone As A Key functionality. This feature enables an authorized user’s phone to act as a key, providing keyless entry and remote control over vehicle functions via Bluetooth Low Energy (BLE) and network connectivity over cellular or Wi-Fi.
As part of a small cross-platform development team, I collaborated closely with testers, designers, and a project manager. This was my first experience with IoT technology at an industrial scale, and it gave me valuable insight into how to seamlessly integrate mobile tech with real-world systems.
Given the premium nature of the Lincoln brand, the app needed to deliver a highly responsive user experience and cutting-edge features that set it apart from competitors. I wrote test-driven code in Swift and UIKit, incorporating RxSwift and other advanced tools to meet the app’s performance and design standards.

Ford Pass App 2.0
At Ford Motor Company, I contributed to the development of FordPass 2.0, the app that connects, controls, and interacts with Ford vehicles such as the iconic Mustang Mach-E and the beloved F-150 truck. FordPass, like its counterpart LincolnWay, uses Bluetooth BLE, cellular, and Wi-Fi connectivity to provide users with seamless control over their vehicles.
This app is relied upon by millions of users across the Americas, Europe, Asia, China, and Australia. As part of the team, I helped deliver responsive, high-performance code that ensured a zippy and efficient user experience. I worked within a smaller cross-platform team alongside designers, testers, and project managers to meet stringent performance and design requirements.
In addition to my development work, I also took on a mentorship role, guiding new hires and peers from various teams, sharing knowledge and best practices to foster collaboration and growth.
My time working on FordPass 2.0 greatly expanded my expertise and solidified my skills as a developer.

Olivia App
The Olivia App was created with love for my color-obsessed wife, Olivia, who inspired me to name this app after her. It combines a fun mini game with a useful tool for my photography needs.
Originally developed a couple of years ago under the name Lumo Chroma, the app’s primary function was to provide different color screens and brightness levels for 3D light painting using the B-mode of a DSLR camera. The app was designed as a tool for creative photography endeavors.
I later expanded the app by adding a mini game that challenges players to match a randomly generated color as accurately as possible using RGB sliders. If the player finds a color they like, they can easily save it for later use in light painting or other creative projects.
The Olivia App is my way of combining creativity, color, and photography into one enjoyable and useful experience.

Rabbit App
The Rabbit App holds a special place in my career, even though it is no longer supported due to the company’s dissolution. This was my first project after completing graduate school, where I had the opportunity to work alongside a small, diverse team of graduate students from various disciplines and countries.
The project involved developing an event hosting and chat app, and it came with unique challenges, particularly as I was working as a freelancer with a team of developers scattered across different time zones and countries. This was my first experience navigating the complexities of remote teamwork, and it taught me invaluable lessons about collaboration, communication, and how to effectively manage time zone differences to meet a shared goal.
Though the app is no longer in operation, the experience was foundational in shaping my approach to teamwork and project development, leaving a lasting impact on my career.
