**Position:** Lead Software Developer
**Job description:** I worked on multiple (Java-based) products at Sterling Commerce:
* I was the Tech Lead for a product called the <a href= "http://www.sterlingcommerce.com/Products/AllProducts/Connect/secureproxy.htm"> Sterling Secure Proxy</a> (SSP v2.0). SSP is a proxy server that resides in a network DMZ - and allows enterprises to securely expose their <a href= "http://www.sterlingcommerce.com/Products/AllProducts/Connect/direct.html"> Connect:Direct</a> and <a href= "http://www.sterlingcommerce.com/Products/AllProducts/Gentran/integrationsuite.html"> GIS</a> deployments to Trading partners across the Internet. This work included:
* * The Design and Development of:
* * A highly scalable NIO based Proxy-framework that was used to power the HTTP and FTP proxies.
* A Ruby/curl based automated system-test tool for the Product (to augment JUnit based unit-tests).
* SSL/Proxy Performance Evaluation and Tuning:
* * Benchmarking on various Hardware/OS combinations.
* PKCS11/Hardware based Crypto acceleration.
* Development of a JNI wrapper to tap into C/OpenSSL based Crypto acceleration (demonstrated 2x Crypto performance improvement).
* Development of a lightweight NIO based replacement for the networking layer in the Proxy (demonstrated 2x - 5x throughput improvement).
* I was the Tech Lead for a product called the Sterling External Authentication Server (SterlingEAS). SterlingEAS is a Security product that is used by other Sterling Commerce products <a href= "http://www.sterlingcommerce.com/Products/AllProducts/Connect/">within the Connect family</a> for things like user-authentication and X509 certificate validation. This work has included:
* * Coming up with an extensible/scalable Product Architecture.
* Managing the Iterative and Test-driven development of the Product.
* The Design and Development of:
* * The microkernel based infrastructure for the Product.
* A (highly scalable) network-server NIO based subsystem.
* Integration of SSL with NIO using SSLEngine (with Java 5.0)
* An XML<->Object conversion layer.
* A Pnuts based automated system-test tool for the Product (to augment the JUnit based unit-tests).
* I was the sole developer for a new product called <a href= "http://www.stercomm.com/Products/AllProducts/Connect/directselect.html"> Connect:Direct Select</a> that was released in mid-2004. This product is a lightweight Java version of Sterling Commerce's flagship data transfer product called <a href= "http://www.sterlingcommerce.com/Products/AllProducts/Connect/direct.html"> Connect:Direct</a>. Being the sole developer, I was responsible for all the activities of the product development lifecycle - Requir
