* Eclipse technical lead for Debug Platform, Java Debugger, API Tools, and PDE (Plug-in Development Environment). Lead a globally distributed development team and participate openly with the Eclipse community.* Completed IBM management courses and act as a first line manager for a local team: interview, mentor, performance reviews, salary decisions, etc.* Lead the design and implementation of tools that analyze binary and API compatibility of Java classes. OSGi bundle manifests define package visibility and custom Javadoc tags define how APIs are intended to be used (implemented, extended, instantiated, etc). The tools report compatibility issues between versions of software and report API use violations within a single version. The tools work incrementally in the Eclipse SDK and in batch mode via Ant tasks consumed by release engineering builds. Java types and references are analyzed by reading class files and simulating class loading in an OSGi runtime.* Developed an asynchronous model driven viewer framework. The framework is used in Eclipse to support a wide range of debug architectures and allows the client (UI) to remain responsive in the face of debug severs that can be latent and unreliable. Updates are rendered in the UI thread as content, labels, and images become available from background worker threads. Background work is scheduled to prioritize updates and avoid conflict with operations/updates in other views. * Lead enhancements and maintenance of PDE as Eclipse migrated its underlying software provisioning technology.

* Technical lead for Eclipse Debug Platform and Java Debugger. Remote lead for a team; Enhancements to the Eclipse debug infrastructure, frameworks, and Java debugger leading up to its initial open source release in 2003. Focused on developing an extensible stable platform and a richly featured Java debugger to support commercial debuggers for IBM and a community of open source debuggers.* Designed and implemented expression evaluation support in the Java debugger. Expressions are compiled into an AST and traversed in execution order while maintaining an execution data stack (arguments, results, etc., are pushed/popped). Message sends are invoked on remote VM via JDI and native operations are performed client side. Developed conditional breakpoints with this support.

* Designed and implemented a debugger user interface in the Eclipse workbench that operates on artifacts and operations common to many programming languages and debuggers (abstracted as Java interfaces). Result is a common user interface that can be shared by many debuggers. Tool vendors provide debugger specific implementations of the interfaces and get a user interface for free.* Lead implementation of a Java debug client based on the open JDI (Java Debug Interface) standard, integrated into Eclipse Java Development Tools. Synchronous Java APIs are backed by a multi-threaded implementation communicating over a socket to a remote VM using a wire protocol to marshal/unmarshal requests, responses, and events.* Designed, implemented and tested a JDOM (Java Document Object Model). The DOM allowed clients to read and manipulate the structure and content of Java source files.Release engineer for distributed development team. Developed custom tools in Smalltalk for code integration, building, and distribution.

* Design and development of views and wizards for VAME (Visual Age Micro Edition – an IDE for Java, written in Java).* Design, development, maintenance, and testing of ENVY/Packager (Smalltalk packaging application).* Researched type inference algorithms and implemented a type inference engine for ENVY/Smalltalk. Simulated virtual machine optimizations via byte code manipulation for dynamically typed OO languages (polymorphic inline caching).

Contract work for New Media Research at the Banff Centre included modifications of VSS (Virtual Sonic Space - 3D audio localization algorithm), the packaging of VSS into a C library for 3rd party use and MIDI control, MAX programming to control a laser disk player, and running the audio components of previously developed VR pieces.
