Software Architect

Responsibilities:

• Responsible for software architect solution to J2EE projects, environmental setting for development, testing and production. Responsible of providing technical help and supervising development teams on several projects. With my supervision teams become more successful and can focus on development instead to lead with settings and components decisions.

Business Infrastructure

Responsibilities:

• Interview with Customers to define requirements and Systems Analysis. Designing Use Case Model for software solution, execute client interviews to get requirements and functionalities definitions in order to set the software model. Using “Unified Modeling Language” techniques. o Working closely to client’s IT teams to get real cooperation among the legacy applications and find out the optimal way in order to provide the integration solution. Using Oracle ESB tools, SOA or other customizable technology.
• Designing solution with SOA to provide Web Services Interfaces. Review for existing applications and study the best way to get this applications communicated and provide the data model and WSDL to represent Web Services and SOAP communication. Using definition and WS test tools like XMLSpy and JUnit test over NetBeans 5.0. My solution was a System mounted on JBoss application server with Axis to save on license cost.
• Design and coding for a Stress application in order to detect performance fails over an specific server architecture with EntireX-Java-Natural-ADABAS. To do this I was programming a multithreading java swing application who can fire many threads to stress the server and the check how it work under load. Prepared an install jar to fire the stress application from different machines. o Coding maintenance of the ActiveX written on C++, even generate new ActiveX to the GUI en the Point Of Sale(POS) application. This is an application over the web but it has to deal with some local peripherals using C++ ActiveX who manage Serial port communication, label printers, money boxes, etc.
• Develop Java Object and package them to get a simple J2EE Framework for XML Database Server and Relational Database Server based on EJB and SOA in order to humanize the assembling job in the business layer to programmers. This framework has data access object, error handling and dependency injection to compose the business objects.
• Development of projects and J2EE Integration based on JSP, STRUTS, HTML, EJBs, JNDI, MVC and design patterns. Do java coding to create classes for the framework and package it on library to make reusable to other projects.
• Prepare configuration for JCA connector over Sun Application Server and JBoss Application Server. This JCA is for access XML native Database Server: actions to do this, read JCA Tamino's documentation, install JARs Library on the J2EE Server Classpath and then make a concept test to see how it works(access XML Database and fire CRUD operations over the XML Data). After this it is ready to implement JCA over the whole solution.
• Preparing JUnit test to check business components. This is using JUnit implementation over NetBeans, preparing the set of test we need and the expected object response, then you can fire the test over the business class and check the results. This help to make test over components without run the whole application and layers over a J2EE server. Also you can do small debug sessions over an small piece of software code.
• Preparing project development environment over Sun Application Server and Testing and Production environment over IBM-Websphere.
• Training to co-workers and prototypes development of to demonstrate J2EE architecture and good practices using new development techniques like Agile Modeling and Extreme Programming. o Develop of Java Libraries to deal with XML data using Xerces Parcer and XPATH.
• Lead team to the integrations of 2 modules over the new application, before this applications would be on different applications servers vendors but after my analysis and test we got the applications working as one.
• Preparing project development environment over JBoss Server and Testing and Production environment over BeA - Weblogic Server. o Concept test and environment setting to use Hibernate-MySQL and Spring MVC framework. Using table mapping tools to represent data entities on Hibernate XML. Make code for high level business objects who manage data operations using Hibernate functions. o Employ of iReport to provide the web application with dynamic PDF pages render using VOI libraries. Code of especial Servlet to help rendering operations for PDF over the presentation layer. o Employ of AJAX to perform operations over the web GUI as the way thick clients do.
• ActiveX integration on JSP code to handle peripherals for the Point Of Sale(POS) application. This is an application over the web but it has to deal with some local peripherals using C++ ActiveX who manage Serial port communication, label printers, money boxes, bar code reader, etc.
• Preadmission Postal Mail Web Module
• This project was started as prototype and my mission was to standardized the Project and improve components design. After my intervention the project was layer designed and with a documentation for develop conventions and deployment configuration for production environment. Prepare a deployment script using ANT. Set the values into the Ant XML to link the libraries (jar) needed on the package for the application and set the values for deployment path. Usually I don't prepare the Ant from scratch instead of I modify some other Ant file created before with a tool.
• Preparing Gantt to control project activities and management schedule for deliverance. Review for the progress on the activities with team and then with the client. The time for each activity on the Gantt chart is taken from the programmers and with the experience measured before in order to get a metric function to gauge the activity.
