Senior Software Engineer, yoonew (April 2007 - September 2008)

New York, NY, US

Tools and Languages: Eclipse 3.2, Apache Tomcat 6, Java, Python, MySQL, Oracle Coherence, Grinder, JUnit, Flex 2, jQuery, DWR, Live Cycle Data Service, Lightstreamer, JMS, log4j, ANT, Maven, Hibernate, JProfiler, TestNG, GigaSpaces XAP

Objective:

• Development of a market exchange platform for sport tickets using a distributed/replicated architecture. The platform runs on a cluster of servers and uses Apache Tomcat 6, MySQL Cluster, Oracle Coherence and JBoss Messaging.

The project is developed in a team of 7 persons

Duties:

Lead Development of the front-end:

• Design and conception of the real time market exchange using DHTML, AJAX. Prices and orderbooks are updated in real time every second using Lightstreamer (Comet Push Server). The site was developed using the Spring MVC Framework, jQuery and DWR.
• Development of a flash chart application to display charts of the product price history. This application implement scrolling and real-time update of the prices through Lightstreamer.
• Design and development of the Flex interface of the market exchange (Yoonew Direct) using Flex 2 SDK and Live Cycle Data Service.
• Design and development of a mobile version of the website using XHTML Profile.
• Developed a java mobile application prototype using J2ME Polish.
• Optimization of the web content by compressing HTML, Javascript using open source tools.

Development of the back-end:

• Development of Price index managements and historical values storage
• Development of bridge classes to communicate to the lightstreamer push server using the lightstreamer protocol
• Development of alert management
• Configuration of Live Cycle Data Service and implementation of services to communicate between the Flex 2 client and the market exchange.
• Wrote methods to process credit card (SALE, AUTH, VOID, CAPTURE)

Development of application/tools to administrate the market exchange:

• Conception, design and development of an administration console application that uses Flex2, Adobe Live Cycle Data Service (formerly Flex Data Service), and JMS.
• Exposed some java methods of the market exchange through JMX

Test developments:

• Design and development of load stress tests to simulate several users placing orders on the market exchange from a browser. This allow to find several bugs that would be difficult to find otherwise.
• Wrote several unit tests using JUnit and TestNG
• Fix and optimize code using JProfiler

Deployment of the application:

• Wrote the build files (ant) to compile, package and deploy the project.
• Developments of python scripts to automate the data creation in the database, generate JavaScript files and check consistency of the node in the cluster.
• Configuration of tomcat (HTTPS, filters, redirection, ..)

Misc

• Wrote some GigaSpaces Services for the next version of the market exchange (price index management, lightstreamer, alerts)
• Installation and configuration of Atlassian Crucible(code repository tracking/monitoring) and FishEyes(peer code review)
• Wrote technical documentation and technology comparison
• Took part in the database design (database schema and hibernate configuration files)

Topics: Peer-to-Peer, Search Engine
Tools and Languages : Python, C (GLIB), MySQL

• Design of a personalized search engine decentralised on user’s computer (P2P architecture). Each computer acts as a search engine on its local data. Collaborative searches are done using self learning algorithms to query the most relevant computers and rank results according to the requester profile.
• Implementation of a simulator to evaluate the efficiency of the system to provide personalized and relevant results to its users. The simulator was developed using the C language and the GLIB library (~8000 lines of code).
• Development of a prototype implementing desktop search, collaborative search and indexation of visited web pages. The program was developed using the Python language (~10000 lines of code), the Cheetah Template engine and the MySQL DBMS. Homepage: http://maay.netofpeers.net/
