Working with teams in New York, London, and Denver to create an API backend for our mobile applications and point of sale system. Spring Boot based applications hosted in AWS on Kubernetes. Integrates with: Auth0 (OAuth2 + OIDC), Twilio, Vertex. Code bases are Kotlin written TDD using kotlin-test, mockito, and Junit5. GItlab CI for CI/CD.

Greenfield Android project for quick service food industry. The application leads the user through a mobile ordering experience where they can create a customized order and pay from their phone. Using Android Architecture Components (View Model / LiveData), Room,and Koin. Integrates with Google Maps / Places Search for store selection. The networking stack uses Retrofit and RxJava. The project utilizes RxKotlin/RxJava 2 to handle threading concerns. Production ready features include obfuscation with Proguard, monitoring with Firebase Analytics / Crashlytics. Testing is accomplished with JUnit, Espresso, Robolectric, and Mockito. We use Bitrise and Firebase Test Lab for CI/CD to deploy to a Play Store alpha channel on every commit.The application was created with a team of three developers, including myself. We have an integrated UX team, and a dedicated quality assurance professional.

Greenfield rewrite and release of a public facing production Android app with 5+ million users.Tech stack: Google Pay, RxJava 1, Dagger 2, Java (started Kotlin conversion when official support was announced by Google), Google Maps, Material Design. Production ready features include obfuscation with Proguard, monitoring with Firebase Analytics / Crashlytics. Push notifications transitioned from Salesforce to Apigee and eventually Firebase. Testing with JUnit, Espresso, Robolectric, and Mockito running on CI in Bitrise with Firebase Test Lab.

Food app for national cafe bakery. I came into this project after my company had been developing it for a while (started in 2014), but was part of a total overhaul as we switched to a new web service platform the client was developing. Technologies used: Google Maps, Java, Otto Event Bus, Crashlytics, Picasso, Roboguice, ORMLite, SQLite, Junit, Mockito, Robolectric, Espresso.

Created a web enabled, barcode scanning application that was fielded by a large agriculture company. The application was designed to manage inventory at the end of the season. Workers scan barcodes of seed bags and can manually enter in details regarding the physical appearance of those seeds. The application was deployed via an MDM to Motorola TC70 Handheld scanners. We used the EMDK for Android to integrate with the hardware based barcode scanner. The application was designed to work offline, so we persisted data to a SQLite database and would sync when the device came online using Android's sync adapter component. This was a Java based project using Roboguice, ORMLite, Retrofit, OkHttp, and Glide. We had a team of two developers including myself, and used TDD to create all the functionality. For testing we used Robolecric, Junit, Mockito, and Espresso.

Developed a suite of applications designed to help first responders assist with chemical, biological, radiological, nuclear, and explosive material threats. The project uses wireless mesh technology to synchronize sensor data across many devices. The goal is to provide situational awareness during an event, a historical record of the recordings, and a collaboration platform consisting of: chat, GIS, and personnel management tools.The technology platform includes a desktop Java application, multiple Android applications, plus a variety of hardware sensors and networking equipment we integrate with.

Worked primarily on the consumer site carfax.com and carfaxbig.com which serves financial institutions by supplying vehicle data over Spring enabled web services. We utilized Spring 3.x, Weblogic, Groovy, Java, Grails, Oracle Databases, and Rabbit MQ for messaging. TDD with JUnit and Mockito: CARFAX practices Extreme Programming.
