SmartRM

SmartRM is a document level security solution. It permits the user to protect files, send them, and keep control of who can use the files and under which conditions. The files are encrypted and the keys are sent to the SmartRM server. Users opening the file have to identify themselves, and will obtain the decryption key only if the correct grant was given by the owner. SmartRM is a 4 component system, with Win and Mac native clients (C++/Qt), a web administration console (Ruby on Rails), and identity and key servers (Java/Spring/Mule).

LaFeltrinelli

http://www.lafeltrinelli.it/
LaFeltrinelli is a major Italian bookstore chain for which we developed a custom eCommerce site from the ground up based on Magnolia CMS, Spring, and Hibernate. The site has complex back-end integration with payment systems, logistics, accounting/invoicing, CRM, and loyalty sub-systems. The site was built by a team of 15 in only six months. My team developed the shopping cart, checkout, and payment gateway integration, as well as integration with logistics and accounting systems.

BPM Web Application

I developed an application for a major pharmaceutical company that formalizes the approval process for promotional materials. In Europe, pharmaceutical promotional materials are heavily regulated and have to pass several approval steps, from internal marketing and legal departments to authority deposit and approval. The whole process has to be traceable and available for internal or external audit at any time. The application was developed in Java/Struts/Hibernate and based on the jBPM OSS BPM engine. After a successful launch, two other departments adopted the application for their approval processes.

HR Application For Tax Filing

A web application that Italian companies use for tax filing on behalf of their employees. It implemented a 300 page specification process mandated by the fiscal authority by importing from the previous year's filings, editing, and transmitting to the authority. The application was developed in Java/Struts/Hibernate in 5 months.
