RECENT PROJECTS

Project Name: EXACT
Company: Consumer Health Technologies
Java Technologies: Spring, Hibernate, Wicket, Drools Jboss Rules, Drools Flow, Maven, Oracle, XStream, Scriptella

Project Description: My task was to develop Business Process Management System for EXACT project which includes:
- Web User Interface for Process Configuration, Process Running, Process Statistics, Documents and Files Repository
- Business Process Designer (Drools Flow)
- Drools Rules Engine
- Centralised repository for Drools Knowledge Bases (Drools Guvnor)
- Business Process Event and Error Handling
- Testing Environment

A business process or workflow describes the order in which a series of steps need to be executed, using a flow chart. Drools Flow provides the necessary building blocks that end users can simply drag and drop onto their canvas when constructing their business processes.

Business Process WorkItem is a building block which consists of:
- Web Service Script which is executed when process reaches this workitem. This script returns Java Object
- Action Block which inserts the object returned by script in drools working memory
- Set of business rules which validate the object returned by script and implement corresponding business-logic
- Action Block which fires these rules.

Testing Environment uses mock web service scripts which return some java object prepared in test setup. Each rule has corresponding test which checks if the rule was fired during process execution.

Validation rules check if the object returned by script is correct. If not, corresponding event is triggered and process flow jumps to corresponding event node which adds error to error log.

Drools Rules and Drools Flow Files are part of Drools Knowledge Base which is stored in centralized repository (Drools Guvnor). Drools Guvnor is a web-application which allows to have access to corresponding knowledge base. Before process is started knowledge base is added to this process by connecting to Drools Guvnor.

Project Name: AREVA
Company: Luxoft
Java Technologies: Spring, Toplink, Struts, Drools Jboss Rules, Oracle, XStream

Project Description: My task was to develop xml validation and generation web-service for Energy Stock Trade System.

XML generation is scheduled for particular time. The format of generated xml files is configured with drools rules. Corresponding process generates xml files using Builder Design pattern.

XML validation is triggered each time the corresponding xml document is stored to database (Using Oracle Triggers). Corresponding drools rules check the format of xml. If validation is failed, corresponding error is added to error log and xml document is marked with failed status.

Project Name: Auction
Company: Freelance
Java Technologies: Spring, Hibernate, ZK

Project Description: My task was to develop Auction Management System with the Scheduler which checks start time
and stop time of the lot. Auction Management System consists of two parts: front-end (user-part), and back-end (admin part). Front-end was written on PHP (not by me). It includes: item lot list page where user can place bids for any active lots. Each time user places bid the stop time of lot is increased by X seconds and the current price of the lot is increased by Y. X and Y are determined from the lot properties which are configured for corresponding lot in the admin part.
Back-end (admin part) was written by me on ZK + Java: It includes item management page and item lot management page.

Project Name: Tembo Project
Company: SDI Media Group
Java Technologies: Spring, Hibernate, JDBC, JUnit, JMock, Hibernate Event System, Jog4J, Ant, Maven, Crowd (Authentication Manager), JIRA, Confluence, Cruise-Control Server, Code Collaborator

Project Description: Tembo is an Enterprise Resource Planning client-server system (client side is on Flex and Server-Side is on Java). This system was requested and is intended for use by SDI Media Group Company, big subtitling and dubbing US company that have a lot of offices all over the world. Tembo helps to manage projects, offices, resources, jobs, tasks, etc. I actively participated in the process of Tembo project development from its very start.

Project Name: Stocks Clusterization
Company: Allarm Service
Java-Technologies: Java SDK5

Project Description: Stocks clusterization by certain statistical positions. It was required to study the stock price time history during the past two weeks and on the basis of this information put the stocks with the similar time history in the cluster-groups. The results of the program were clearly seen on the stock price time history charts for the different stocks. The stocks, which were in the same cluster had the similar charts. To put the stocks in clusters I used mathematical tool of graphs, finding the complete graphs among the number of result graphs. These complete graphs contained the stocks from the same cluster in the form of the graph points.

Project Name: Main Server
Java-Technologies: Java SDK5, java.util.concurrent library, RMI
Company: Allarm Service
Project Description: The development of the software module which is responsible for the stock exchange trade information gathering during the current day and for keeping this information in the form of different statistical positions.
