Confidential, Mendota Heights, MN

Consultant

Environment: Android, .NET, Xamarin.Android, C#, MVVM, REST/Web API, MySQL, Google Cloud Messaging (GCM), TokBox, TFS, Agile, NSubstitute.

Responsibilities:

• I was responsible for architecting and building an Android application for a set-top box. The set-top box is connected to a TV via HDMI which displays the UI. The device has built-in Wi-Fi interface.
• The architecture used MVVM pattern. The business functionality was implemented in RESTful layer. A data layer abstraction was used for CRUD operations between service layer and MySQL.
• The UI/View is primarily built using .axml definitions and associated Activity artifacts. The Model layer contains the business logic/functionality; this layer also is the consumer of the REST layer. Model gets consumed by ViewModel to allow interactions with the View. A Data Binding allows ViewModel to ensure that the Views get updated data.
• Video calls are implemented using TokBox API.
• The Server and the UI Client exchange short messages using Google Cloud Messaging (GCM). They are used to push down/up notifications.
• Automated Unit Testing is planned using NSubstitute.
• Presently, Android SDK 4.2.2 (API 17) is being targeted; but, it is likely to be revised higher.
• An iOS version of the application is likely to follow. So, the architecture is designed to allow code reuse up to ViewModel layer. The Views are expected to be native to each OS.
• I was part of the team responsible for designing and developing cross-platform mobile solutions for Ecolab's products and services .
• Used Confidential 's in-house cross-platform framework iFactr, developed parts of the application that provide cleaning and energy-efficiency solutions to industries such as Food & Beverage and Hospitality .
• Used design patterns and industry best practices to design and develop elegant and maintainable solutions .
• The application was architected using MVC pattern into various layers . The data layer was abstracted out with mappers tied to physical layer (SQL Anywhere). The business functionality was implemented in a Business Layer, accessed by Controller’s Action Methods. It’s a thick-client application; so, the offline client on mobile devices is running its own database. The local DB is synced up with the master on a server via a Sync app.
• The app is interfaced with an external Ecolab-specific hardware called Ecolab Controller. It is used to tie the application to Dispensers responsible for mixing and dispensing various cleaning chemicals. A separate Controller Mapper provides the abstraction and allow the app to interact with Ecolab Controller. Field personnel use their mobile devices to configure and access various functionality on the Ecolab Controller, thereby controlling the cleaning functions via the Dispensers.
• Some of the built-in UI controls were customized to provide additional functionality to meet client requirements. Examples include Bool Fields and Required Text Boxes with Icons. Such custom controls were isolated to their own layer to provide an abstraction, as the app needs to remain cross-platform.
• Ecolab has large presence in a number of countries; and, the app is expected to be launched in each of those countries. So, all strings and literals were isolated to resource files and tables. A separate translation service is utilized to translate into respective languages.
• Automated Unit Tests were performed using NSubstitue. A separate Test Project is created for each project in the solution. The Test Class contains the “substituted” instances; these are then registered and made available in a Test Method, as dependencies.
• A Simulator app was created to replicate some of the functionality of Ecolab Controller hardware. It’s a straight C# app that listens to mobile app as it tries to communicate to hardware. It is primarily used to test the mobile app, in a limited way.
• A number of helper libraries were written to centralize non-business functionality.
