Role: Hadoop Consultant

Confidential was not incubated by businessmen in boardrooms rather it was an outcome of the efforts of a small group of passionate software engineers turned entrepreneurs, whose objectives were purely technology-enablement and commitment driven. service delivery and decision making is achieved because of our adherence to our core value systems marked at the time of our inception. These values guide and help us draw our business and service lines.

• Lead Hadoop developer for core tools group. Setting up the Hadoop Cluster and developing the map reduce applications to handle the data from the library definition files. Architected Big data solutions to handle millions of records.
• Developed, maintained and tested core technology software modules for cadence tools group in c and c . Supported platforms using Linux, Solaris and IBM-AIX.
• Improved the software quality by proactively identifying and fixing purify and valgrind bugs.
• Plug-in software development: Specified and implemented key plug-in for Cadence library definition files.
• Wrote test cases and implemented a testing software suite. Provided migration path for Cadence applications to adopt this new plug-in.
• Design library management software: Lead developer for a critical high-visibility project involving migration of Integrated Circuit design library management software to the Cadence next generation design database Open Access . Consistently completed milestones as per schedule delivered successful code on schedule.

Role: Lead Consultant

• Software Engineer for HAP team. The High Availability Platform HAP of Motorola provides a highly available platform designed to support applications providing reliable service with 99.99 uptime. Designed, implemented the Proxy Component client-server model which acts as conduit communication state, configuration, statistical, diagnostic information from the HAP to call- processing payload cards and vice versa.
• Designed this to be multi-threaded server, to accept client request using a predefined TCP/IP socket and port. The call- processing payload cards triggers events on the server side by sending IP data to the Proxy server's listening socket. Also on the server side, events like data value change, alarms raised, critical error reported etc would trigger callbacks, which the Proxy Component receives and sends out the info to the play load cards through IP data packet.
• Designed and implemented with the capacity to handle high volume information transfer by taking full advantage of HAP's high availability and to handle multiple play load cards requests.
