Enterprise Architect

Confidential

Responsibilities:

• Define & Implement Omni Channel API Management Digital Strategy Across Confidential, AutoZone & AutoAnything
• Define & Implement Identity Federation, SSO and protection against OWASP Top 10 vulnerabilities using OAuth2, Open ID Connect and JWT/JWS/JWE
• Define & Implement Analytics platform leveraging Flume, Solr, Morphlines and Angular
• Define REST standards, HATEOAS implementation, service virtualization and automated functional testing
• Define and Implement distributed storage for Media Services with GlusterFS
• Define event based integration roadmap for customer data integration
• Defined Continuous delivery pipeline
• Define & Implement Search Architecture
• Explore technology landscape that align with Confidential Business objectives
• Confidential ’s core business is data publishing. In 2010, Confidential needed an Omni Channel delivery strategy allowing them to publish data via different delivery channels such as Mobile, Browser and Direct B2B Integration.
• I identified API Management as a digital strategy for Confidential to meet its business objectives and spread the business from NA to Europe. As part of the API Management strategy, I assessed various API Gateways such as ApiGee, CA’s API Gateway (formerly Layer7), WSO2 and Intel Mashery’s offerings. For Confidential, CA’s API Gateway was a better fit and hence I was responsible for adoption of API Gateway across Confidential, AutoZone and AutoAnything.
• As part of the API management strategy, I was responsible for defining the API security, API Technical stack, API Testing, API Analytics, Continuous Deployment roadmap and API monitoring.
• A key requirement to data publishing platform is the ability to search the relevant data quickly. I introduced the concept of ontology management and implemented search architecture via Solr to provide free form search and improve the search ranking via ontology management.

Senior Architect

Confidential

Responsibilities:

• I was involved with design of highly available (5 9s), high speed store and forward router that handled 80K messages per second with guaranteed delivery. The key technologies involved were C/C++, In-memory database from McObjects, GUnit and FPGA based messaging middleware from Solace.
• I was responsible for IOT architecture/design/delivery/performance tuning of HACC program, which included suite of applications with 5 9s availability, high frequency, and low latency message processing. HACC was design to scale horizontally with latency in order of microseconds between components. The key technologies involved were C++, Boost, Dependency Injection framework called PocoCapsule, GUnit, GMock and FPGA based messaging middleware from Solace and Linux System programming.
• I was responsible for redesign of the legacy UI portal and middleware services. The technology stack included java 1.7, spring framework, spring integration, hibernate, maven and Tibco Rendezvous for messaging middleware.
• Net Control was a large initiative to replace legacy mainframe applications with distributed architecture. My main role was to design, develop and implement the core domain model. The technologies used were Java, Spring Framework, Junit, Jmock and Tibco Rendezvous for messaging middleware.

Enterprise Architect

Confidential

Responsibilities:

• The above platform was designed in response to a radical change in the SmithBarney’s business model. SmithBarney has transitioned from a fee based to advisory based business.
• This radical shift required IT to provide tools to the FA which would allow them to provide superior advisory services using relationship paradigm.
• Hence, I was responsible for solution architecture of the new platform that would allow FA during the discovery of the new clients, restructure existing households from account based to relationship based structure and provide a total view of a client’s relationship & assets.
• The new platform adopted CDI methodology to provide a single unified customer view.
