Essbase is a multidimensional database management system (MDBMS) that provides a platform upon which to build analytic applications. * Primary responsibilities include managing the deployment architecture of the legacy Essbase product offering for both cloud and on-premise, working with senior management on developing strategic initiatives, and providing guidance to cross-functional development teams on the evolution of the product architecture to meet those initiatives.* Delivered the Oracle Essbase on Oracle Cloud Infrastructure (OCI) offering, providing a strategic path for customers to migrate their customized on-premise environments to OCI, showcasing the best practices as well as integrations with key OCI Services.* Managed a small team of developers working on the core Oracle Essbase product, focused on deliverables pertaining to lifecycle and platform.

* Researched and developed prototypes for tactical features and architecture to determine viability and development costs for senior management. Examples include developing an architecture and implementation roadmap for deploying on kubernetes for better resource utilization and lower operational costs for the Oracle Analytics Cloud offering.* Designed and implemented the artifact storage layer for the Oracle Analytics Cloud offering, creating a high-throughput REST API around an RDBMS store.* Responsible for the architecture of application metadata lifecycle across different components within the BI 12c platform stack, identifying product gaps based on short-term and long-term requirements.* Led and mentored engineering teams on technical design and implementation of key features.

* Developed many of the core features of the AudienceDirect (AD) product including the REST API, JSF UI components, security, workflow, using standard JEE and open-source technologies.* Implementing key features in the YieldEdge (YE) product, working on infrastructure, solving problems with performance and a large memory (up to 256GB) footprint.

* Created the next generation architecture for the tool set managing the metadata lifecycle, introducing standard development methodologies to the modeling process, providing a flexible solution for customers and a broad solution adaptable to current and future requirements.* Create and manage the overall technical design of the next generation modeling tools, leveraging existing JDeveloper and Metadata Services (MDS) technologies, reducing development and maintenance costs.* Coordinated with Essbase and Oracle BI teams to create a common design-time metadata model, making it possible to consolidate model development tools across the stack.* Mentoring developers on technical design.

* Lead a team of engineers on key infrastructure features.* Tightly integrated the product to the common infrastructure as part of the EPM product suite, providing integration to Hyperion Shared Services, Oracle Weblogic server.* Built integrations with Oracle BI Enterprise Edition, Oracle Identity Manager, and Oracle EPM Planning.* Implemented SSO solutions with Oracle Fusion SSO and Oracle EPM SSO.* Implemented security features and ensuring the product followed Oracle security standards.

* Built the reporting services infrastructure, including a Multi-dimensional Expression (MDX) query engine for accessing what-if multi-dimensional data and metadata.* Designed and implemented an XML for Analysis endpoint for executing MDX queries using the industry standard SOAP protocol, allowing for integration with third-party reporting tools.* Designed and implemented the rowsource infrastructure for storing and querying what-if tabular data, used as a data source for the multi-dimensional engine.* Created a design-time metadata service using XML and JAXB technologies, providing an abstraction layer for metadata modeling independent of the runtime engine.* Ported the product on the Apache Tomcat, IBM WebSphere, and SAP Netweaver J2EE application servers on the Windows and Linux operating systems.* Led the SAP Netweaver certification effort for the Dynamic Operational Planning platform.* Led development and customizations for several Fortune 200 CPG and manufacturing customers, using standard development methodologies for a successful implementation and deployment.* Managed the build infrastructure and the Perforce source control server.

* Designed and implemented the role-based access control security model.* Maintained deployment and runtime of the Sourcing product on BEA WebLogic and IBM WebSphere J2EE app servers.* Designed and implemented the clustering feature, which eliminated the single point of failure for the bid processing engine, introducing data partitioning schema for increasing overall system scalability. This feature produced libraries for efficiently managing cluster communication between nodes that ended up being used by other Ariba products.* Significantly increased overall system performance by re-architecting the topology, eliminating unnecessary network latency for data accesses. Effort resulted in recognition from management.* Responsible for the development and installable build environments using Ant and PERL.

* Worked on the infrastructure team for the Dynamic Trade product. * Implemented database level archiving to improve overall system performance.

* Developed a distributed medical image processing system using a market-oriented approach for distributing processing load.

* Part of the technical team building tools based on research as part of the Digital Library Project.
