We're pretty good at making web applications and e-commerce sites. We've been doing AJAX well before the term was even coined. Sometimes we build customer-centric sites, where users can get information on your organization, buy your products, and so forth. Other times we build applications for internal use, perhaps for data entry, or converting old desktop applications to more useful varients.
That's not necessarily the end of the story though; our first goal is to make sure you're satisfied, not to sell you a custom application or website. There are all sorts of existing software out there written to solve a variety of problems, many of which are high quality and free. Don't let someone convince you to pay them to develop a custom solution, when the product has existed in the Open Source community for years!
Let us know what you're interested in, we can work together to figure out the best solution.
