Employment & Key Achievements
Technical Lead Apple Sep 2013 till date Wipro
• Developed Messaging based solution using RabbitMQ, Hazelcast distributed caching & Cassandra
NoSQL Database
• This assured Data Consistency across Service instances & Propagation of data changes within an SLA
of 8 ms (& overall Data Propagation within an SLA of 35 ms)
• Involved in debugging of issues related to Data Setup / Environment impacting the functioning our
HTTP based WebServices (built with proprietary WebObjects) and thereby impacting Apple Online
Store (www.apple.com)
• Architected & Designed a Fault Tolerant Solution to make existing services Highly Available with a
goal of near to zero downtime. Solution proposition included developing micro services, usage of
Oracle Service Bus for fault tolerance and Data Center based affinity cache to enable stickiness and
avoid data unavailable situations
Architect MasterCard Sep 2010 – Aug 2013 Wipro
• Architected & Designed end-to-end solution to re-write their 20-year-old legacy system that handles
Credit Card disputes (like Chargebacks, Retrieval Requests, Case Filing) to move to Java, J2EE,
Spring, Hibernate & ext-JS based Web application
• Did feasibility study & prototype use of third-party tool – Snowbound Software, for ability of
multiple file upload, scanning & other document management features from within our web
application
Architect Qualcomm Aug 2008 – Aug 2010 Wipro
• Provided Solution Architecture & Design of System Integration Solution to China Telecom –
customer of Qualcomm.
• As China had 31 provinces, there were different telecom providers. Challenge was to be able to
interface with the 31 different billing systems and adhere to the integration specification provided by
Shanghai Research Institute
• Owned & Coded a Router Component – a HTTP based web service – that routes calls based on a
routing table that uses IMSI-MDN mapping to instance-port that hosts service for a province. This
component has a key responsibility in the overall architecture of this solution as the hardware was
limited and we had to provide high availability of the services – And the IMSI-MDN based routing
approach worked best
• SOAP services were also built. Some SOAP consumers had to be built to interface with external
billing systems
Sr. Software Specialist General Electric Oct 2004 – Aug 2007 Patni Computers
• This was the first project where I learnt & adopted UML in creating Use Case Realizations,
Component, Class & Sequence Diagrams
• This was also a first for me to own and lead a complete E2E implementation using Java, J2EE,
Hibernate, SOA. Applied Service Locator, Façade patterns
