° CapCom (Capital Commitment - Client Facilitation Trades)

The primary purpose of this project is to track the profit and loss on client facilitation trades, which enables traders to commit capital in the form of a risk price for a client order. The P&L is calculated on a theoretical basis, comparing the traded price with the client against an average price (VWAP) in the market. The resulting P&L on the capital committed is a key part in analyzing client profitability and trader performance.

Technically, it is a 3-tier client server application, where C# GUI tier interacts with Java middle-tier via CORBA-like custom library and queries an Oracle 10g database using Hibernate. Also there are few communication channels with other internal applications using CORBA and Tibco EMS.

I was involved into design, development and support of all parts of application at a position of Team Leader. Also I developed an amount of application monitoring tools using shell scripting and Java, implemented lifetime reconfiguration tool using JMX.

° PhotoSite.

This was a social networking web application based on photos sharing and printing aimed to Belorussian market.

This is a Java application and it queries an MySQL database using Hibernate. The results passed back are processed and transformed into XML via Commons-betwixt. The XML is parsed by XSL and then displayed on the front end.

I took part in designing application and developing both core functionality and front-end part.

It was a Fixed-price project and it was successfully finished in time.

° Flight Booking Engine for Lufthansa.

Flights and Hotels Internet reservation system. Java, Struts-based application queries Amadeus Global Distribution System calling XML-based web service and Oracle DB using JDBC, transforms results into XML and displays at the screen after XSL transformation.

I developed GUI XSLT part and implemented OTA2Amadeus and vice-versa XML formats transformation framework.

° HotelBenchMark.

Web application for benchmarking Hotels by visitors, scalable for easiest integration with any hotel reservation systems. I took part in designing application starting from creation of UML diagrams and developing including both core functionality and front end part. Java, servlet-based application queries MySQL DB using JDBS, then converts results into XML via Castor and displays at the screen after XSL transformation. Was optimized for JBoss application Server.

I used the following languages, tools, and technologies:

·         J2EE, Java, XML, XSLT, JavaBeans, Maven, Mysql.
