Web Applications provide users the capability of accessing applications that can be accessed over internet or an intranet. The architecture of the web based applications is N-tier architecture that uses client side scripting languages, has multiple application servers that can be hosted on different servers and backend as database. We have experience and expertise of developing secure, robust and scalable web-applications. We develop web service applications that provide scalable services due to a well thought and carefully designed architecture,which provides support to multiple clients interacts with various application server. Our architecture also helps in minimizing transaction time which we ensure is the one that is acceptable from the end user’s perspective (though transaction time also depends upon the hardware and the network speed). Security of these web applications can be a major concern. We ensure that our web applications are secure by using secure protocols like SSL and HTTPS when required. We encrypt all sensitive data before storing it in the database, which are later decrypted before presenting it the respective end-user. Tokenization of URLs is also done to ensure security in web based application. Also, whenever needed, we can provide APIs to poll/ping external databases of the clients securely. We have successfully implemented web applications in financial, healthcare supply chain and e-commerce domain. Our experience also includes developing comprehensive web services solutions for connecting healthcare supply chain, ecommerce engines and detailed advertisement solutions with mobile technology.
