Skills

Open Source Open Standards

At B-inIT Consultancy Group , I am lead consultant in Open Source group. We are very active in usage and development of following products: Eclipse , Hibernate , JBoss , Tomcat, and MySQL . We believe that with applying Open Source s and Open Standards our customers can avoid expensive vendor locks. Very good example of this is JBoss Application Server .

J2EE

I am a J2EE Software architect with 6 plus years of experience with J2EE . I led successfully a couple complex projects with small and large teams, covering various aspects of software development, process and methodology. With my extensive experience in Object-Oriented design and development, Java , J2EE , middleware and enterprise application architecture and implementation, I help my costumers to implement ICT systems with low TCO.

Over the past 6 years I have witness J2EE platform become the proven technology for implementing large-scale distributed application in such a short time. With new Java ^TM 5 and EJB3.0 things are becoming easier and more transparent. The technique is very flexible, but may organizations have problems with changing internal processes to adapt to new needs. Agile development process will deliver enough control and flexibility to reach new goals.

JBoss

With pleasure and proud I have used JBoss as reliable application server for various projects of mine. JBoss AS is the first J2EE 1.4 certified, production-ready, open-source application server on the market, delivering a high-performance, reliable platform for e-business applications. Combining a revolutionary, service-oriented architecture with a no-cost open source software license, JBoss AS is free to download, use, embed, and distribute, making it the most popular middleware platform for developers, independent software vendors (ISVs), and enterprises alike.

By simplifying the way developers interact with the middleware services, JBoss AS enables IT organizations to deliver greater value in less time. Faster development, combined with a zero-cost software license, greatly reduces overall business costs. Best of all, support for JBoss AS is delivered by full-time JBoss product experts and certified JBoss partners, making JBoss AS the safe choice among enterprises for powering their mission-critical applications.

IBM Websphere

Many organizations still deploy legacy application on z/OS operating system. IBM WebSphere Application Server has grown to be a successful application server platform. With IBM WebSphere Application Server on z/OS, the preferred application server platform gains the benefits of capacity and robustness from the mainframe legacy. It also gains access to data and transactions residing on z/OS subsystems such as DB2 and CICS . This software has very high license software but for some large ICT organizations it still delivers low TCO. I have worked with IBM WAS on z/OS for last three years.
