Member of the engineering team of AMPS, a high-performance streaming database product in production with thousands of instances deployed worldwide. Server development in C and C++ on Linux, and client API development in C, C++, Python, C# and Java on Linux and Windows. A heavily multithreaded codebase for a distributed system that optimizes for performance to meet our customers' latency, throughput, and scale requirements. Accomplishments include:- Responsible for hands-on support of cross-functional teams within large customer organizations to assist with issues and develop long-term strategies and solutions to meet varying requirements. Many support engagements went beyond direct product issues to focus on in-depth analysis of Unix hosts to identify resource contention as contributing factors-Determined root cause for numerous defects, identified both internally and reported by customers, driving fix from implementation through to delivery.- Led design and implementation of publish filter feature to support conditional publishing- Implemented sorting engine to take advantage of parallelized sorting algorithm while queueing requests from a single thread to limit extraneous thread creation.

I am a developer for the product line which includes real-time, perpetual analytic ‘engines’ written in C/C++/Java that have ETL, data quality, “entity resolution”, and alerting/analysis components backed by RDBMS systems (DB2/Oracle/SQL Server.). A primary consideration in writing this software is performance and scalability to billions of records and terabytes of data, while retaining high quality entity analytic functions. The AR product builds upon the same entity analytic technologies and adds another dimension of cryptographic one-way hashes to enhance privacy protections. Day to day responsibilities include investigation, design input, development, debugging, porting, quality engineering, documentation, and assigned product maintenance tasks. I regularly participate in design meetings and provide support to internal and external customers.

SRD was a small start-up which was acquired by IBM in December of 2004. The product line was an entity analytic engine backed by an RDBMS. Primary responsibilities included development, design and debug of the core entity analytic engine.
