As a solutions architect I designed and implemented scalable distributed systems using Skytide's analytics platform. These were multi-tier data pipelines feeding OLAP aggregation servers which supported web-based reporting dashboards. I built analytics systems for customers such as Netli, Limelight, Akamai, ClearChannel, Telefonica, Ericsson, Rostelkom, and Tata Sky.Responsible for all phases engagements: from requirements gathering, specification, capacity planning, implementation, production, and maintenance.Experience integrating and analyzing a broad spectrum of datasets: structured XML documents, http logs, flash, wms, Omniture, doubleclick, Adaptive Bit Rate streaming.Worked closely with field sales representatives by producing POCs for the sales cycle.

Worked on Plumtree's search server (formerly Ripfire), on a project to convert from single-node to more scalable multi-node system. Extracted indexing module from server to a shared stand-alone component.

Designed and implemented a report generator feature for Kaplan’s Distance Learning Platform running on JBoss. This feature allows developers of online courses to specify custom report content and format via XML and Java.

 Designer and lead developer of business logic infrastructure for the B2B Contract Compliance product built on a proprietary EJB application server and integrated with Oracle ERP. Designed and developed XML dialects and tools to support definition of customers’ B2B contract terms and other business data. Developed library of java classes to support the definition of complex pricing policies such as tiered discounts, rebates, and incentives. Contributed to design of the Oracle ERP adapter. Led team of four engineers dedicated to this project.

Supported clients and integrators implementing applications built on our proprietary B2B platform. Roles included team leadership, project management, client relationship management, training, mentoring, design, coding, trouble-shooting. Designed database schemas and EJB object models to support client business processes for B2B web portals.

Architect/Consultant Designed and developed a pure Java distributed multimedia delivery product suite for broadband networks. Releases 0.9-1.1.2: In the server, I designed and implemented the load balancing, scheduling, thread management, session management, message queuing, connection pooling, and implemented the optimal dynamic bandwidth allocation strategy. Designed and implemented a distributed console application for configuration and management. In the video player SDK, I designed and implemented the proprietary buffering strategy, fail-over, and fault-tolerance.  Release 2.0: Designed and implemented a Redirector component and its content management database application, including a custom solution for object-relational mapping. Designed and implemented dynamic content distribution between video servers.

11.9 SQL Server Release: Responsible for stabilization and debugging for lock management, access methods, and utilities. Developed 2 chapters of internal training course for SQL Server Administration.

Server Resource Manager Group: Responsible for a wide variety of components that manage in-memory resources such as logical locks, buffer caches, and RDBMS meta-data. Enhanced and maintained the lock manager through 4 major releases of the SQL Server, including design and implementation of lock manager support for the major rewrite of the server to support row-level locking. Designed and implemented the ‘drop column’ feature, which allows the user to reformat an existing table by removing all the data in that column. This included enhancements to the logging and recovery systems. Designed and implemented the ‘explicit table locking’ feature.

SQL Server Internals Group: Responsible for re-engineering the internal infrastructure of the SQL Server. Contributed to the design and implemented the cleanup manager, in support of the Global Error Handing project. This component managed a registry of all internal resources acquired by a server thread, providing a way to release the appropriate resources in the event of an error. Conceived and implemented an error simulation system to exercise SQL Server error handling code. Implemented SQL Server built-in data transformation libraries.

Test Tools Group: Developed and supported test harnesses, utilities, and database applications that comprise the software test systems for all Sybase products. Designed and implemented tests for SQL Server, connectivity libraries, and front-end products.

Develop, run, analyze automated tests for SQL Server and other products.
