PROFESSIONAL EXPERIENCE:

Confidential

Senior Software Engineer

Responsibilities:

• Understanding client's requirements and their feasibility.
• Interaction with client's business to discuss, project and propose development scenarios - in the form of User Stories-.
• Design and implementation of back-end platform, front-end architecture and security model.
• Development and implementation of UI components, layout and messaging system in order to effectively communicate/glue them as the application grows in complexity.
• Application security testing and quality standards.
• Implementation and development of unit tests (jUnit and Jasmine).
• Debugging and troubleshooting.
• Analysis, code reviews and unit test documentation.

Senior Software Engineer

Responsibilities:

• Abstract: Design and implementation of the Enterprise Services Platform (ESP) within a Service Oriented Architecture (SOA) by applying the principles of reusable software components which can be integrated together to support multiple business needs in a consistent manner by exposing the Message Model which would include the definition of request and response messages schema and/or exceptions.
• The platform itself will be the basis for future projects based on the same architecture, reducing costs of software implementation by promoting the reuse of services for business needs and shorten time-to-market of product delivery to customers. The platform is developed entirely in the Java EE platform using Maven, Spring Framework, Hibernate/JPA, XStream, Gson, Log4j; deployed on an Oracle WebLogic cluster and a few instances of Oracle RDBMS system.

Senior Software Engineer

Responsibilities:

• Design and implementation of specifications and work packages for security vulnerability patches for on-going project in the Java EE platform; additionally, participating in the implementation for penetration testing for some vulnerabilities - XSRF, XSS (and variants), SQL Injection-. Configuration and execution of HP Fortify software to check source code for further/remaining vulnerabilities. MF-Process Data Services is deployed on Oracle WebLogic, utilizes simultaneously a Sybase ASE and IBM DB2 databases, a WebMethods integration server, and an IBM MQ server for asynchronous messaging/communication.

Senior Software Engineer

Responsibilities:

• Design and implementation of specifications and work packages for security vulnerability patches for the Java EE platform. Configuration and execution of HP Fortify software and plug-ins to check source code - security vulnerability assessment. MF-Portfolio Values is deployed via UNIX shell scripts that pull the source code from IBM ClearCase, build it and deploy it on an Oracle WebLogic box; databases in use are Sybase ASE and IBM DB2. It is mainly a Web application compounded of many functional modules and two Web modules; relevant technologies are Spring Framework, Apache Struts, Hibernate, ILOG JRules, JSP/JSTL and JasperReports.

Confidential

Software Engineer

Responsibilities:

• Design, development and implementation of a new system for transferring information between pension systems — basically granting interoperability by sending/receiving XML information in a decentralized, asynchronous way via WebSphere MQ; likewise interacting with an enterprise transactional IBM DB2 cluster.
• Analysis of future use of Web Services (REST-like). Also responsible for structure and end-to-end development of such system under the Java EE platform and Spring Framework. As a pilot project we implemented an application to handle security, calculation of interior/exterior payments, retirements, disabled beneficiaries, shares, etcetera.

Responsibilities:

• Responsible for structure, implementation and development of the overall architecture for an Intranet-based home application — there should be a shared platform for projects in future. The system was developed under the Java EE platform, Spring Framework, Apache Struts, Sybase ASE as database engine and IBM WebSphere as application server.
• Release and deployment management for applications and infrastructure; monitoring capacity and support for IBM WebSphere as well as supporting the migration from SharePoint and Microsoft SQL Server to Alfresco ECM and MySQL. Also Involved in the design and implementation of Alfresco workflows and BPM designs with the Activiti engine.
