Helped promote the wider adoption of Kotlin within Walmart. The omnichannel team adopted Kotlin for all new development shortly after I joined the organization. I wrote a guide on code style and best practices and included tooling like "ktlint" for improved code quality.Authored a new internal framework to unify the barcode scanner functionality across Walmart’s Android app. This improved both code quality and the end-user experience. Required collaborating with a variety of other product teams, including Walmart Pay. This feature allowed customers to perform tasks like price checks, prescription refills, and import paper receipts.

As the first Android engineer, I led the development of Simple's product for Android. The foundation we built served us well in the following years as the product increased in size and complexity. We grew the team to eight Android engineers during my tenure.Later, I became lead engineer on the first cross-functional product engineering team at Simple. I went on to lead the engineering effort for the integration of Plaid’s account linking solution into our mobile and web applications. Following that, I was lead on a small team that integrated two-factor authentication into our mobile and web sign-in flow.Simple had a large microservices infrastructure supporting the client applications. Much of our work involved integrating with these backend services via REST APIs. We used libraries like OkHttp, Retrofit, Moshi, and Google’s AutoValue to make these integrations easier and reduce the amount of boilerplate code required.Features I was directly responsible for:- Transaction History- Transaction Search- Support Messaging- Photo Check Deposit- Block / Unblock Card- ATM Finder- Two-Factor AuthenticationSimple's backend infrastructure was primarily written in Scala using the Dropwizard framework. However, we had several JVM microservices running Clojure and JRuby. Everything was hosted in Amazon's Virtual Private Cloud (VPC).As a financial institution the security of our customer's data was paramount. I worked closely with our internal security group on threat modeling and mitigation.

Prior to their acquisition by Esri, I helped Geoloqi build their native Android developer SDK and architect their web APIs. I was responsible for writing code, producing documentation and providing developer support. I built an SDK for the Geoloqi API on Android; maintained the Geoloqi Android Titanium Module; and worked on developing battery-efficient solutions for mobile location-services.

I was one of two engineers responsible for building the Dark Horse Android comic reader application, which in early 2012 had over 20,000 installs and a four and a half star average rating on the Android Market. The app has since been installed on millions more devices.In addition to the Android client, I worked with a small team of developers on several Django, Python and PHP web applications. Our team was also responsible for maintaining the Things From Another World web store (tfaw.com).
