PROFESSIONAL EXPERIENCE

2006-present Altera Corporation, San Jose, CA
Senior MTS
Lead engineer for the Nios II Integrated Development Environment. Nios II is an embedded soft-core processor for Altera FPGA's. As a general-purpose CPU it requires a full-featured C/C++ development environment. The Nios II IDE is a specialization of Eclipse/CDT targeting the Nios II processor. Responsibilities included specification, development and release engineering for the product.
Result: Upgraded the IDE to latest Eclipse releases and enhanced functionality and features. Increased customer satisfaction and drastically reduced defects.

2004-2006 Siderean Software Inc., El Segundo, CA.
Senior Software Engineer
Worked as a member of technical staff in the engineering department, on a number of critical technologies for the flagship Seamark Navigator product. Built up Eclipse-based infrastructure and rolled out to the team, greatly increasing productivity. Built-out test harness infrastructure based on JUnit and CruiseControl. Quickly developed the Seamark 3.6 UI based on XML/XSLT, and incorporated new features. From requirements to full prototype in one week.
Result: Immediate impact on the product.

Architect for a Spring-based component and security model for the next generation Seamark 4.0. Design included the ability to run without Spring for testing purposes. Security model was orthogonal to component model, allowing it to be transparently added to the product without disturbing existing code.
Result: Fully functional component and security models.

Rapid response to customer need for logging. Customer made data-logging a requirement for closing a deal, I designed and implemented this feature in three weeks from first notice to ship.
Result: deal closed, revenue generated.

2003-present simontuffs.com, Pacific Grove, CA
Independent Consultant
Open Source Software project creation and delivery. Created and published four open-source projects in under six weeks in the areas of Java installers, network benchmarking, XML based services and an Eclipse plugin.
Result: one-jar.sourceforge.net, soap-stone.sourceforge.net, xml-xig.sourceforge.net, and jar-plug.sourceforge.net released as open-source.

Web-Services Consultant for PushToTest (www.pushtotest.com). Designed, implemented and verified server-side software used for XML scalability studies on BEA/Weblogic and Sun Java System Application Server. Customers included General Motors and Sun Microsystems.
Result: Performed multiple contracts on-time and on-budget with satisfied customers. Initial contract taken from RFQ to sign-off in only fourteen days.

Collaborated with Stidolph Software Engineering in a contract with Siperian Corporation to produce a discrete event simulation of their J2EE based system to help them analyze its architecture.
Result: Simulator met customer requirements and exceeded expectations.

2000-2003 Lutris Technologies Inc (Gridion) Santa Cruz, CA
Senior Staff Engineer
Member of engineering team that created the J2EE Lutris Enhydra Application Server. Major areas of development included the deployment subsystem and classloaders. First to deploy and debug the J2EE Pet Store application on this platform. Conceived the idea for a 'restart' product based on Grid technologies. Developed the basic Grid-based computing platform concept and 'sold' it to the team. Created rapid-prototype of system, and handed off to the engineering team for implementation. Created rapid-prototype of Job Submission Language (JSL) by heavily leveraging the open-source Ant project. JSL allows for programmatic-control of jobs as they are executing on the Gridion platform and has become the pivotal API in the product.
Result: Lutris was able to re-start as Gridion Inc., after laying off all but a core team of 5 engineers and 2 executives, instead of filing for bankruptcy.

Created fully-working prototype of Grid-based XML accelerator (based on XSLT). As part of due-diligence proceedings, a Venture Capitalist (VC) required proof of concept for an XML/XSLT accelerator based on our Gridion platform. Under extreme time pressure I designed and produced a fully working prototype, and performed tests and analysis of data to demonstrate potential ROI for customers of this system, with actual linear speedup up to 16 processors.
Result: successfully convinced lead VC to continue with Gridion.

1997-2000 Octant Technologies Inc, Sunnyvale, CA
Co-Founder and Systems Architect
Systems-Architect and lead developer of the Tiburon simulation environment. Integrated Systems was realigning its business, and our team and customers did not fit their new direction. I was instrumental in the spin-off in the role of Systems Architect. Tiburon is a software/hardware platform that can perform real-time or data-driven simulations on a range of topologies from networked Unix workstations to multi-processor VME based systems. It is the simulation engine in use on the Space Station program for flight-readiness testing of hardware before launch, and was also recently used as flight hardware for the AFRL XSS-10 mission.
Result: Octant Technologies is basing its new contract proposals around the Tiburon (renamed Orion) platform, and continues to grow.

1990-1997 Integrated Systems Inc, Sunnyvale, CA
Research Scientist
Lead scientist on development of Multi-Model Simulator for Honeywell MATE program for the Space Station. Honeywell/Boeing had committed to using a simulator from Integrated Systems Inc, but it would not scale up to the size of simulations that they needed. My team of four engineers created a first release of a product to solve the basic problem and stabilize the business relationship between ISI and Boeing, and then went on over a period of 12 months to completely solve the problem. On at least two occasions our work was on the critical-path for the entire Space Station project. This simulator is currently in use in various facilities around NASA, including the Johnson Space Center, essential in pre-flight testing of modules for the Space Station.
Result: $600K new contracts for Integrated Systems with follow on product sales, and Honeywell was able to deliver $60M of products to Boeing/NASA.

Led subcontract software development projects within the Advanced Systems Group for large aerospace corporations such as Lockheed, Motorola (Iridium), Boeing, Honeywell and Harris. Led many projects including software design and development for the AutoCode C and Ada products automatic software generators.

1995 Borland Interactive, Scotts Valley, CA
ATLAS Team Manager
Management of a team of four engineers on the Atlas project, part of a rich-content email delivery system

1989-1990 Ready Systems, Inc, Sunnyvale, CA
Senior Ada Engineer
Integration of the Telesoft Ada environment with the Ready Systems VRTX real-time embedded operating system.

1985-1989 Alcoa Technical Center, Pittsburgh, PA
Staff Control Engineer
Control systems design and implementation, software development, real-time systems development, signal processing.
