E-commerce applications were developed for IBM Germany and IBM Worldwide. I was an official IBM contractor. Following projects were assigned to me and my team: IBM Common Custom Classification System (CCCS) and IBM Electronic Transport Order (ETO).

CCCS Application is to provide custom classifications of IBM merchandises to the users and other IBM applications. It contains about 5000000 custom classifications to all products that IBM has ever produced. System is available to all the countries where IBM has local departments. Application has a front-end (web) interface available for the users and backend interface available for other applications, usually for mainframe applications. Backend processes use MQ-series to contact needed service of CCCS application.

ETO Application is a system to connect local IBM departments with local transport carriers. It provides facilities to assign orders to carriers and track how the orders are processed.

2002-2003 Role: Sub-Teamleader This position assumed management of six Java developers in Minsk/Belarus.
Responsibilities included technical project management and some administration activity: tasks assignment, preparation of timesheet reports to project managers, Java code review, and creation of internal (low-level) application designs. My job included implementation of the most important tasks that were assigned to our team (specially various business transactions). Our team also provided database management. It included creation of DB2 DDL files, SQL migrations scripts, creation of DB2 Java stored procedures. Production DB2 databases were located on PowerPC servers cluster and mainframe MVS host.

2001-2002 year. Role: Software Developer
Responsibilities: It included development of the new business transactions and support of the both applications (CCCS and ETO). Java code had to be developed using WSAD v.4.X and 5.X as main development tools (From the earlier beginning Visual Age for Java was used). Management of local test servers WAS 4.x and 5.x WTE. It also included preparing code to deployment on the production WebSphere server on AIX environment. Code had to be synchronized with CVS repositories on the regular basis. Some of my tasks included usage of the WebSphere embedded MQ. Production and test queues were accessed using MQ Java libraries. Database access layer development using EJB CMP beans and Session bean facades was also part of my job. UI development included validation of JSP pages according IBM internal standards for User Interface. Borland C++ 5.02 was used to create custom text editor and the JSP syntax checker utility (check JSP pages according IBM internal standards).

Application used Tomcat as a web application server. Microsoft J++ was used as a main development tool. Borland InterBase was used as a database server. Borland Delphi 2-4 was used to create local windows clients for the database server. The application included custom authentication and authorized models. It used Servlets on the presentation tier and some custom classes to provide access to persistence data via JDBC. Java application was basically used to perform dynamical data inquiries. Also some backend processes were created to provide some time-consuming data analyses. Delphi clients were used to fill data in the database.

A medical drug classificatory was developed. Classificatory was created to provide custom search of medical drugs using type of drug, medical class and medical group. It provides different sorting modes (price, availability) for the users. Application was supposed to work on W32 platform. Delphi 2.0 Application was used as an IDE. Paradox (Borland Database Engine) was chosen as database server.
