• Worked on Openwave voice/video messaging server (OVM): This product has been deployed across several Tier1 customers across the globe and has close to 10 million subscribers actively using the features/services of this product.
• Involved in developing new features for this product.
• Worked on various other features of this product including some key architecture level performance bottleneck issues in terms of connection pooling and memory management to improve the overall product architecture. Was able to successfully resolve key issues by proposing and implementing new solutions.
• Was also involved in development and fixing issues of other components related to this product i.e OSG (Openwave Services Gateway), SIP Proxy Server, Call Control Relay Server.
• Worked on Notification Manager (NM): This product has also been deployed across several Tier1 customers across the globe and has close to 10 million subscribers actively using the features/services of this product.
• Worked on developing new consumer for this product i.e SIP PUBLISH consumer. This involved designing and developing a new consumer right from scratch. This involved integrating with 3rd party SIP Stack vendor and creating a multi-threaded scalable application to meet the performance requirements. This was implemented using C++/LDAP/TCL. This is now live in one of our Tier1 customer and handling traffic successfully.
• Was also involved in development and fixing issues of other components related to this product i.e Eventrouter, Notifyserv, other consumers.
• Later on was also involved in supporting the Tier1 customers on the issues related to this product. The customers span across the globe. So this involved a strong technical expertise and operational process to handle the escalations. It also involved managing / planning and providing releases to customers.
