First off, I’m not looking for work. I will consider helping out charities or other worthy causes on a part time, best effort basis. But please don’t contact me about new professional opportunities.
I’m a proven engineer and manager with over 30 years of software and hardware development experience, I have a passion for leading edge technologies such as Amazon Alexa, IoT hardware and software, the latest Apple technologies, and Maker culture. I want to work with world class innovators and creative thinkers; working hard to reliably deliver outstanding products, as well as helping to encourage, train and motivate the entire team and others. I enjoy learning from others, and helping others to learn. Technology is moving at warp speed. Keeping up is challenging. I like to contribute to keeping it fun for both the team and our clients.
I have worked successfully as both manager and developer in engineering teams of a wide range of sizes, from working by myself to directing over 50 software engineers. My preference is always to remain hands-on; leading, mentoring, consulting, but still contributing directly through participation in coding, code reviews, and architecture and best practices discussions.
Senior iOS Developer, H-E-B Austin, TX – 2018-Present
I love working for H-E-B. I’ve been blessed to be part of the small team responsible for the PartnerNet iOS app. This is an iOS app for H-E-B employees (we call ’em Partners, because they are, and hence the name).
Senior iOS Engineer, Mutual Mobile, Austin, TX — 2015-2018
I have greatly enjoyed organizing and facilitating companywide hackathons on Alexa, Arduino, and brown bag training in preparation for it. I have conducted lunch-and-learn sessions on topics as diverse as “iOS Key Value Observing”, “Creating Printed Circuit Boards”, and Alexa skill development.
Examples of recent project work
- Serverless backend for a VR experience
I designed and implemented the back-end for a VR solution. I leveraged several AWS services, primarily API Gateway and Lambda. Code was implemented in Node.js using test driven development, and deployed to multiple stages using a combination of bash scripts and the AWS CLI.
- iOS Application
I was part of a team that implement a complex iOS application in Swift utilizing Test Driven Development and the VIPER architecture. I implemented several parts of the application working with visual designers to implement their UI designs, along with designing and implementing the business logic associated with those components.
- Alexa Custom Skill
I designed and implemented a healthcare informational skill in Node.js. This skill is basically a voice help desk to assist users with questions about their healthcare plan coverage and costs. This was deployed to multiple stages using the AWS CLI and bash scripts.
- IoT iOS Application
I implemented an iOS application used to demonstrate the capabilities of a BLE IoT prototype board. An image representing the board was positioned in 3D space in real-time, tracking the movements of the board. Addition metrics were displayed such as acceleration and button activity, and a UI presented allowing the user to control the state of LEDs mounted on the board.
- Personal Open Source Project: Patriot Hobbyist IoT Framework
I love implementing IoT hardware and software in my spare time. I released the Patriot frameworks to help others with their IoT projects. Simply including a library into their IoT firmware projects allows the Patriot Alexa Smart Home skill, iOS app to automatically detect and interface with their custom devices.
