    I have over 5 years of experience in developing web applications using Java, Scala, Spring, Play, Hibernate and JavaScript. I have developed highly concurrent, reactive applications on the JVM, as well as large-scale enterprise apps that worked with legacy databases. Currently, Clojure and Scala are my tools of choice when working on my side projects. Recently, Elixir has become a part of that as well. In the past, I have developed full-scale apps using Objective-C and, ahem, PHP as well. I have been working with Scala and Clojure for quite a long time now. I have been a long time user of git, mercurial, gradle, and maven with some experience with sbt. Apart from these, I have dabbled in a lot of languages and frameworks like Go, Ruby, CoffeeScript, Groovy, node.js and several others. I have an ability to pick up new things easily. I learn new things almost everyday. I am always on the lookout for new tools for solving problems. And I have always succeeded in coming up with elegant solutions to programming problems.  less

    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.
