I took part at regular meetings regarding elaborating application requirements, clarifying them, detailing them.
I was involved in task elaboration, task estimation, task allocation, elaborating application tests scenarios and application development along with automated tests.
AGILE was used as a software development methodology along with SCRUM and KANBAN.
The applications were developed using Java 6. Struts 1, JavaScript, jQuery, JSP and Servlets were used for user interface development. JDBC was used for database communication, Apache tomcat as an application server, Junit, Mockito for automated tests and Maven as a build tool

General description

I was the team and technical lead responsible for maintenance and developing new modules for SIVGIS a Geographic Information System (GIS) using AGILE methodology and coordination of a 3 members development team.

Activities and responsabilities

SIVGIS is a Geographic Information System(GIS) Java 5 desktop application given into production in April 2009 for APIA (government Agency for Payment and Intervention in Agriculture). SIVGIS was built as a custom set of Eclipse plugins along with other open source plugins such as GeoTools and uDig. Application user interface was developed both in SWT and in Swing. Application business was partially implemented using EJB 3 over a JBoss 4 server and partially using an ESRI GIS solution. Application data was stored in an Oracle database accessible from the persistence layer of the application via JPA 1 or pure JDBC for performance issues. Eclipse was used as the main development tool, Apache Ant as build tool and Jira as issue tracking.
I was also responsible with development and maintenance of the Enterprise Resource Planning application APIA, application integrated with SIVGIS. Both solutions were developed for the Agency of Payment and Intervention in Agriculture (APIA) part of the Ministry of Agriculture.
I took part at regular meetings regarding elaborating application requirements, clarifying them, detailing them, task elaboration, task estimation, task allocation and development monitoring.

Achievements

I was responsible with maintenance and developing new modules for web based enterprise resource planning (ERP) application TravelMaster using AGILE methodology

General description

web based application developer

Activities and responsabilities

TravelMaster application was developed for Tri-Pen, a USA based company and it was used in production for managing cost control related to all aspects of the traveling industry. It has a layered architecture having a user interface layer written in Struts framework along with JSP, custom JSP tags, JavaScript, Apache Velocity and DWR (for ajax). The business layer was written in pure Java. The persistence layer used JDBC and OJB persistence framework over an Oracle Database. Apache Ant was used as a build tool, Eclipse as development tool, SVN for source code versioning, Jira as issue tracking tool. The application was deployed over a BEA server instance
I took part at regular meetings regarding application requirements, architectural changes and technologies used for implementation.
I analyzed and proposed architectural changes for migrating to newer technologies like JSF or Struts2 instead of Struts 1, using Hibernate persistence framework instead of OJB and introducing Spring container in order to improve productivity.
I improved application quality by reducing the number of technical problems
