OpeSystems (BEPENSA).

http://workbycloud.com/aplicaciones

Dec 2011 - Apr 2015.

Place: OpeSystems.

Location: Mérida, Yucatán.

Position: Analyst Programmer, Advanced Analyst Programmer, Project Leader.

•Construction of WorkByCloud Android Applications (450 private users), while learning to use languages that were compatible with JVM in order to optimize Android coding.

Applications:

SmartOrder (Sale). In production, in use.

The main aplication. A point of sale for small self-service stores that sell CocaCola products.

Crédito (Credit). In production, in use.

An application that followed the number of clients using credit.

Dialogos de Valor (Value dialogues). In production, in use.

Application that provides dialogues that the salesperson had to have with the small business owner.

Conteo (Counting). In production, in use.

This application is used so that the person in charge of re-stocking vending machines can take count of the needed types of soda (brand and presentation), and place orders accordingly.

SOS (Out of stock). In production, in use

When a self-service store is out of stock, the owner uses the application to place an emergency order to the BEPENSA call center which is open 24/7.

Cobranza (Collection). In production, in use.

Application used by BEPENSA salespeople to register payments collected and their sales routes.

For all applications, the technologies used are:

•Consuming RESTFul Web Services, with JSON as a data transfer structure, using Retrofit (http://square.github.io/retrofit/), and custom libraries with HttpClient library (http://hc.apache.org/httpclient-3.x).

•JSON manipulation with Gson (https://code.google.com/p/google-gson) and Jackson.

•For database was used the technique Object-relational mapping (ORM) using the OrmLite (http://ormlite.com) library.

•Applying Aspect Oriented Programming for injecting code via AspectJ (https://eclipse.org/aspectj), with advices and inter-type declarations. Some modules for production, another for testing.

•Improving Java 6 adding Lambda expressions using Xtend (https://eclipse.org/xtend) language.

•Adding Libraries via public and private Maven (https://maven.apache.org) repositories.

•About Android SDK: Use of Handlers and Threads to do CRUD operations in background. Note: we had a performance issue using while AsyncTask class. The CRUD operations were slowing down by each onProgressUpdate call, which is why it was changed from AsyncTask to the Handlers and Threads set.

•Use of Broadcast, Services, and Content Providers for inter-communication between apps.

•Use of Google Cloud Messaging (https://developer.android.com/google/gcm/index.html).

•Conteo application content was presented with a ListView. However, a focus issue was present: the user selected an item, but when he proceeded to type something else, the focus was lost and the first typed character was automatically selected and deleted by the time you typed the second character. The problem was solved by changing from ListView to RecyclerView.

•Java Annotation was used to generate code.

•Java Reflection API was used to access and manipulate Android classes.

•Communication with Bluetooth printers. Improving the print with HTML as layout (in conjuction with CSS and Javascript (AngularJS). Getting a Bitmap from WebView to create a ticket image with specified width in dip units. The bitmap is dithering to get an 8-bit image to be sent and printed.

•In laboratory testing (not in production) I implemented an application that used iBeacons technology. Using the SDK Estimote Beacons Android SDK (https://github.com/Estimote/Android-SDK), the app consisted of identifying Coca-Cola vending machines.

•Coding Unit Test with JUnit 4 (http://junit.org). Used for Android apps as well as Java libraries.

•Using Git as a version control system, managed with SourceTree. Using free accounts in BitBucket (https://bitbucket.org), and private repositories with Bonobo Git Server (bonobogitserver.com). In the beginning SVN was used.

•Eclipse, IntelliJ Community, were the IDEs was used for development.

•Android Levels: 8, 19, 20.

Developing CRM 2011 and CRM 4 plug-ins using C# for the backend and HTML and Javascript for the front end. These plug-ins were used by the company to optimize their costumer follow up process. It was also used to produce reports of personalized indicators.
