• Physician Registration - physician referral to specialists, radiological diagnostics, diagnostic feedback to physicians and patients.
• Content management was done on Joomla 1.5. Installation of Zend Framework for PHP applications.
• Employed lean methodology through UML use case analysis and domain modeling to perform object oriented analysis and design (OOA/D) and applied Agile methods of software development including SCRUM, pair programming, test driven development, code refactoring and use of design patterns. Familiar with Rational Unified Process of software development and testing.
• Developed code on Eclipse/Linux for the Android (mobile computing platform) patient management system. Installation of Eclipse (Ganymede) with plug-ins for Java Android with SDK 2.1, 2.2 & 2.3.
• Linux system administration including configuration of Apache Web Server 2.x, networking and virtual hosting; create local network with virtual sites on Apache 2.x web server to enable communication with iPhone/iPod-Touch.

Confidential (Software Architecture & Development): Design and develop PHP and MySQL code for coupon management with the following capabilities - merchants can create, modify and delete coupons as part of on-line advertisement; consumers can browse, clip, print and email coupons; administrators can manage users, merchants (integrate with Google Maps) and approve coupons.

Confidential :

• Designed and developed a unique role based security system using digitally signed credentials for the Internet using several Java technologies both for web using servlets, JSSE (Secure Socket Extension for SSL/TLS over HTTP), JCE (Crypto Environment for DES, RSA) libraries, digital signatures using DSA, MD5 as well as client server using Java Swing, RMI and TCP/IP socket programming.
• Multi-modal Patient Information System: Using the Java programming language, developed a XML based content model with XSLT stylesheets to manipulate data and display content in various formats including PDF, PS, HTML on Apache's Cocoon running off Tomcat Servlet engine. Used XQuery for XML data processing. Previously developed healthcare workflow system using Apache\'s Cocoon on Tomcat servlet engine and an XML database featuring Xindice. Used XSLT /XQuery/XPath along with pipelined actions through 'sitemap.xml' to access and transform XML content based on user role (RBAC) and state.
• Prepare course material for network security. This course material is still being used as of 2011 being taught at various engineering colleges for students of computer science, information technology at the bachelor's and master's level. Statistics show more than a thousand students used this course material.
