    I am an electronics engineer, XML consultant, technology evangelist, and frequently published technical author. After graduating in 1995 from the University of Engineering and Technology, Lahore, I began designing software solutions for industrial control systems. Later, I turned to XML and built web- and WAP-based XML processing tools, server-side parsing solutions, and service applications. Since 2006, I have focused exclusively on Java- and XML-based open source tools and solutions. A strong advocate of open source tools, I not only design solutions based on them but also train software and IT personnel at Lahore universities in using open source technologies. I am the author of JasperReports 3.6 Development Cookbook (Packt Publishing, 2010). Please see my following articles that I've been writing to display my work.
