    I'm a software developer from India with a breadth of development experience including desktop and web applications using Java, build engineering, and web application development using python/Django. I also have experience in working on components like ADF which is a JSF implementation. Also on wide variety of web servers likes of Tomcat , Apache , Weblogic Server . Unlike many programmers I have a thorough knowledge of my craft and rather than hammer away on projects I use my solid problem solving skills to think through the problem at hand and devise an intelligent solution. I believe in approaching work with a view of scalable long term solutions rather than short term hacks , while honoring the time line. In addition to knowledge in a breadth of programming languages (Java, Python) that I can use to create custom business software solutions, I also am well versed in the administration and maintenance of common web application environments. Programming skills apart, I have a good command of the English language to be able to articulate thoughts very well and that makes me a great Content writer. My ability and skills in researching for information are honed over 10 years of working with many big guns in the Software industry. I can deliver content and articles that perfectly match your requirement, are concise and effective. If you're looking for a moderately priced alternative to American programmers who has the same skill set, ability to communicate effectively in English, and a history of delivering completed work on time and as directed I'm your guy.  less
