Work Experience:

Acision, Richmond VA C/C++ Software Engineer September 2009 - Present

Acision develops the mobile messaging software, providing communication solutions for network operators and service provider. In addition to baseline call answering capabilities, I developed advanced features from scratch such as Enterprises Auto Attendant (EAA), Screen & Intercept, Anonymous Mailbox, Audio Read Receipts, Auto forwarding, Broad cast Alerts, Message Playback Speed Control and many more features. All the projects I worked are under AGILE/SCRUM environment.

Project 1: Audio Read Receipts

This feature allows operators to offer voicemail only subscribers who don’t have email service the ability to access read receipt messages in their mailbox via the Telephone User Interface (TUI).

Responsibilities:

· Designed the C++ coding architecture by using Object Oriented Approach.

· Implemented the message classification based on the flags for Message Disposition Notification (MDN) identification.

· Implemented C++ coding for MDN classification and message aging for Read Receipts.

· Developed the XML call flow for using this feature by end subscriber (includes set / resetting LDAP attributes) and tested it.

Tech. Environment: C++, XML, STL, GDB, UNIX, JXplorer, Clear Case, Clear Quest, LDAP, REST API’s and Eclipse

Project 4: Message Auto Forward

Message Auto-Forwarding allows a subscriber to forward all new messages received via message deposit to be forwarded to another subscriber's mailbox. It can be configured in 3 modes regular, silent and delayed modes.

Responsibilities:

· Developed REST API to toggle the Auto Forward feature.

· Implemented the C++ code for basic auto forward delay feature, implemented a handler to handle this event including storing the time and to calculate the delay time.

The setting of the Vendor Class Identifier VCI (Option 60) is to inform the DHCP server about the hardware type and functionality of the device. The value that this option is set to gives the DHCP server a hint about any required extra information that this client needs in a DHCP response. In our scenario, we are going to use this option to tell the client about which IP address and configurations file to take.

Responsibilities:

· Designed functional, procedural hierarchies of DHCP state machine such as DISCOVER, OFFER, REQUEST and ACK states
