Employment (Feb. 1999 - present)
Principal Member of Technical Staff, Oracle Corporation.Principal engineer in the Oracle Data, Indexes, and LOBs group.
Implemented J2EE 1.3/1.4 compliant JMS provider for Oracle Containers for Java (OC4J).
Implemented J2EE 1.3 compliance for Oracle's Java Messaging Service (OJMS).
Participated in the Architecture Task Force for Oracle's Unified Application-to-Application and Business-to-Business Integration Solution.
Designed a C++ version of the Java Messaging Service (JMS) API for access to the Oracle AQ queuing system.
Implemented extensions to the Oracle JMS API to allow browsing on JMS Topics (multi-consumer queues).
Architected a Messaging Gateway integrating Oracle AQ with non-Oracle queueing systems (MQSeries, TIBCO, MS/MQ) using the Procedural Gateway of the Oracle RDBMS and the Oracle Message Broker drivers.
Architected, designed and implemented the BPC (Business Process Coordinator), an execution engine for high-level, declarative business models describing enterprise-wide application integration.
Coordinated proof-of-concept demonstrations of the BPC at McDonalds, Agra Systems, and Envera.
Provided QA, configuration management, build, and installation support for BPC and OMB (Oracle Message Broker).

Implemented a collection of optimization algorithms, based on executable rewriting (using the EEL/PP toolkit), to improve the instruction cache performance of programs on a superscalar, pipelined architecture (UltraSPARC in particular). The collection of programs studies ranged from the SPEC benchmark suite (integer/floating point), to X-windows applications, to large database servers (Oracle/Informix/DB2).
Implemented a source-to-source translator from Java to C++. The translator (consisting of a parser, AST, and code generator) was used to study the performance of (interpreted) Java programs compared to (compiled) C++ equivalents. The runtime support included a reference-counting garbage collector.
Implemented a collection of algorithms, data structures, and animation frameworks for Computational Geometry in 2 and 3 dimensions.
Designed and implemented a framework (based on the Paradyn Performance Measurement System) for performance data collection and semi-automated, self-tuning algorithms for programs based on dynamic performance information.
Implemented a portable, synchronously-scheduled, lightweight thread library (in C). The library is currently used extensively in the Paradyn Tool.
Implemented a type inference algorithm for a Object-Oriented, functional programming language. Also implemented a code-generator, exception architecture, and memoization for the language targeted at a RISC-like virtual machine.
Implemented a code-generator backend for the SPARC architecture and to be used as part of the LCC compiler.
Implemented a syntax-macro system to extend the syntax of the C language with a wide-range of arbitrary extensions. Demonstrated the use of the syntax macros to implement exceptions, function closures, and new statement types in C.
Implemented a file-access library based on B-tree and Hash indices for use in a toy database system. The library was designed to be highly configurable in terms of buffer cache sizes, file page sizes, buffer cache page replacement policies, indexing and hashing algorithms and used in studying the effects of these parameters on the performance of a database system. The library is in use in the Minibase database package developed at the University of Wisonsin-Madison.
Implemented a connection-oriented, reliable, TCP/IP stack on top of a connectionless, unreliable, unordered messaging layer.
Ported the IPS2 Performance Analysis tool to the Solaris-2.x system. This involved instrumenting the C library and the MT lightweight threads library to collect detailed performance information for use in subsequent analysis.
Implemented a process migration system for checkpointing the state of a running Unix process on one machine and restarting it on another. Demonstrated the system by implementing a WORM capable of reliably completing an application in multiple copies across a network of workstations, with the ability to tolerate failure of hosts and processes.
