·         Took company from R&D environment, using Unix/C/C++ to a flexible, product-based environment (Apache, MySQL, PHP).  Put together 6-month resource plans and project schedules.  Managed the technology and defined deliverables for strategic business relationships.  Liaison with 3rd party software developers.

·         Implemented 65% Performance Improvement to Terabyte Oracle Production Data Warehouse, included Schema redesign, table partitioning, indexing, data reduction, SQL and Pro*C optimizations.

·         Technical Architect and Project Manager of MediaPlanner, the key technical product for the company.  Designed the database, which included solving the “parts explosion problem” within a relational database.  Managed the 6 person technical team to create a web-based, layered product, that allows Media Planners to start with demographics and psychographics and plan out their media campaign.  Technology components I used were MySQL server database implemented via middleware layer of JSP/JavaBeans (jdk1.2.0_02) using a JDBC 2.0 driver and HTML presented from an Apache Server, to complete the 3-tier architecture.

·         Designed and implemented an architecture which allows real-time deployment of our custom content by non-technical webmasters.  This entailed creating multiple, robust constantly running processes programmed in C and C++, with multi-threaded socket calls across redundant servers.  The processes update nameservers in master/slave relationship and deploy new and changed content displayable at users’ sites.  Architecture optimized retrieval while supporting redundant, independent servers.  Designed a user-friendly, web-enabled front-end for the process.

·         Maintained and extended the internals of a proprietary web server written in “C”.  Transitioned from proprietary web server to Apache.  Implemented the new website:

·         Created a Virtual Account Database which used web-spidering agents to pull together information from financial accounts in numerous other databases.  Implemented schema and all database access/update routines in C++/SQLServer.

·         Designed, implemented and benchmarked data parallel algorithms for Oracle server applications on shared-memory processor (SMP) Unix systems.  Techniques included named pipes, threads, mutexes, ramdisk, embedded SQL (Pro*C++), Oracle Parallel Query Option, disk striping, advanced SQL and indexing techniques and data buffer cache tuning.  These C++ algorithms were then used to make performance improvements in project work.
