Unisys sofftware partitions the hardware so that multiple guest OSes may work on it simulataneously. We work on the bugfixing and maintenance of this software which is primarily written c and c#.

ARRIS is embedded device manufacturer that makes modems/routers/gateways. Work involved developing software in a fast paced environment usijng a myriad of technologies most of which are from the opensource community. Here are some of the examples of my work:

Developing backend functionality within embedded device using C/C++.on Linux platform.

Protyping FactCGI as a replacement for CGI.

Development of BLE embedded server component for Device onboarding.

Bug fixing and maintenance.

Design and development of Mobile application backend on Embedded device using PHP

Design and development of HNE autoconfiguration feature that allows auto configuration of extenders connected to the router/gateway.

Initially researched on enabling containers in an embedded device. The device used was a Raspberry Pi 3. As the project proceeded the work involved was changed to integration of plume and testing of Plume REST api using Postman application.

Depending on the URL that's being accessed using mobile network a charging policy was applied to the customer that was accessing it. Example: Facebook access is free while Techcrunch could be charged depending on the data size.

Tech 47 is a team that worked on porting opensource software to 64 bit so that it could be used internally in a modified version of Linux platform.

Datablitz is a main memory database used in telecom networks to provide fast access to customer data using SQL. Primarily owned by Alcatel Lucent, the product had very few competitors one of it being Oracle TimesTen. Work mainly involved bug fixing maintenance and integration of a new SQL engine to the core database.

Interworking function is a product that connects 2 afax/fax machines in order to transmit data from one end to another. However the product that I was working on was to perform the same thing using IP packet network instead. The work involved making using of PPTP protocol.

Megisto content based charging switch was a telecom network component that charges the customer based on the size of the content being accessed. The charging switch analyzes the data that is being transferred through the ip network and charges the customer based on the policy configured by the telecom service provider. The accounting information is then passed to the Radius server periodically.

A software product was created by then Lucent for the migration of customer information from an older version of software to a newer version of the software. This software required constant maintenance and upgradation depending on the telecom software being used.

Datablitz is a main memory databased used for telecom networks for its efficiency and speed while also making using of SQL interface for the ease of access.
