Major things that I have done with Java include: - Implementing business logic and service layer components - Integration with databases - Developing and integrating with in-house and third-party web services (such as payment gateways (e.g. Paypal), SMS gateways, AWS APIs and other Government / non-Government integration endpoints).

I have very strong experience in using the Spring framework and its dependency injection feature for developing comprehensive web applications. Other Spring libraries that I came across and am familiar with include: - Spring MVC - Spring Security - Spring Batch: for developing modules to handle batch processing of scheduled tasks - Spring Integration: to cater for enterprise application integration needs - Spring Data: to interact with various databases (e.g. MongoDB, MySQL) I have ongoing experience with most of these technologies and using these technologies I am capable of implementing most customer needs and use-case scenarios.

Though I am not primarily a creative designer or multimedia content provider, in many instances I can resolve minor to moderately complex image and audio editing needs. I can also create / edit vector graphics. My expertise with opensource tools like GIMP, Inkscape and Audacity often cuts down the need to wait on the availability of a dedicated UI designer or multimedia content editor.

I spent 2 days being stuck on a problem that Tanvir was able to get to the problem of very efficiently. He obviously did plenty of research before our eventual meeting and was ready to take me through his discoveries. It was a very worthwhile investment.

Designing, architecting and implementing a full blown single page web application. Working on each and every layer of the application and its development lifecycle from ground up. This also includes continuous delivery and continuous integration of the project on Amazon AWS. I am the only developer on this project and quality is something that has been ensured from day one. The application is being developed following a TDD approach and it has over 1,500 test cases (just to give an idea of the its extent).
