Since January 2016 I have been part of the engineering team for a ground-up rewrite of Google Earth, one of Google's best loved products and among my personal favorites. The new implementation launched in April 2017 on web and Android, with IOS (iPhone) to follow shortly. The multi-platform architecture starts with a common core of C++ code for Earth rendering and core application logic. The core is wrapped in platform-specific presentation code (JavaScript, Java and Objective-C) to provide a fully-native look and feel. On web, this is an unusual architecture -- the C++ code can be delivered in either Portable Native Client (pNaCl) or Web Assembly (wasm) form.

Google Maps Engine (GME) was Google's premier enterprise-grade solution for geographic data processing in the cloud. As a member of the "Core" engineering team we developed and maintained server software infrastructure the product. In January 2015 Google announced that GME would be discontinued. I remained as part of the GME "Sunset Cruise" team until we shut the service down in January 2016.For several months at the start of this period I assisted in the development and support of one of Google's oldest Geo products: "Earth Enterprise" is a tool set which provides enterprise customers of Google Earth with the ability to generate their own globes from proprietary data. The product is used by government agencies and infrastructure-oriented businesses throughout the world.

From January 2012 through the end of 2013 I worked on a next-generation version of the "My Maps" feature, in addition to supporting the legacy "My Maps". The new product was launched as "Google Maps Engine Lite" and "Google Maps Engine Pro" in 2013. In late 2014, the new product was officially rebranded as the new "My Maps".

In January 2011 I took on the Tech Lead role for the "My Maps" feature of Google Maps, as the Monetization responsibility moved elsewhere in the company. Besides supporting a product with millions of users, my major accomplishments were to lead the in-place re-implementation of My Maps using Google's "Fusion Tables" storage backend. The same My Maps client software (part of Google Maps) was capable of using either Fusion Tables or the legacy storage. On completion, however, we decided not to launch the Fusion Tables version, and instead began implementation of a wholly new solution.

As Tech Lead for Monetization of Google Maps and Google Earth, I was responsible for the design and implementation of various projects to improve the coverage of and revenue from ads on Google's geographic products.Personal contributions have included: - Ads for geocode results - Design and implementation of MapClips (the little ads at the bottom of the map). - Design and implementation of asynchronous panel ads (ads that are updated after the page has loaded). - Design and implementation of experiments in redesign of panel ads. - Re-implementation of infowindow results for location-based ads.In addition, as Tech Lead I have contributed through my team to the implementation of - "Reverse Business Lookup" ads for geocodes. - Ads for Google Earth. - Ads for driving directions.as well as other strategies and improvements.

As a member of the Google Maps engineering team, I participated in a variety of projects from 2005 until my involvement tapered off in 2012 to work on the entirely separate "Maps Engine" based version of My Maps. Significant projects during the first two years included: * "Street Views" street level imagery. * Send-to-car and send-to-email. * Multi-point driving directions. * Various geocoding improvements. * Rewrite of Google Maps printing, including implementation of print preview window. * Specialized improvements to driving directions (e.g. through roundabouts).

After consulting for StrataLight in Campbell for one year, in 12/2003 I became a regular employee (Senior Software Engineer). The following September I became the Software Manager, directing a very talented team of 6, while continuing my own engineering responsibilities. Designed and implemented a Web-based Element Management System in Java on an embedded Linux platform for StrataLight's carrier-grade long-haul 40GB optical terminal system. The interface is novel in several respects: * Supports event-driven client updates in near-real time by continuously streaming HTML and JavaScript to an off-screen IFRAME element. * Page content is determined by live XML data bubbled up from managed entities. * Much higher level policy is implemented by defining XPATH expressions in the property meta-data. * Uses an XML page layout language.

This was my big career change, away from compilers and toolchains and into WWW technology and business development.Major projects included development of ClassWorld.com and several internet publishing projects.

My first (and so far only) "middle management" job. Located in Sunnyvale I directed up to 40 engineers and 5 managers engaged in the development and support of open-source GNU software tools, including C and C++ compilers (gcc/egcs and g++), debugger (gdb), GCJ (Java compiler), glibc (C library) and the proprietary IDE tools "Code Fusion" and "Source Navigator".

Transferring out of HP's compiler lab after 12 years, I joined an in-house technical consulting group. Here I worked with HP-UX software developers at Synopsis, Avant!, Viewlogic on porting and performance analysis of EDA (Electronic Design Automation) applications.

After 11 years as an HP manager, while completing my Master's degree I became an engineer on the code generation (compiler back-end) team for what's now known as the Itanium or iA64 processor architecture. Implemented code generation for various operations, and generated stack unwind data structures. Designed and implemented stack unwind class library for use by debuggers, simulators, the HP-UX kernel, and other programs that need to reproduce and examine the machine state in previous stack frames.

In 11 years as a manager at HP's compiler lab in Cupertino, I managed at various times the engineering teams for the following compilers: C++, HP Pascal, HP COBOL, Ada/300 (68000), Lisp/800 (PA-RISC), and HP Business Basic. Other responsibilities:-- Managed HP's involvement in Pascal, and COBOL language standards committees. Also involved with LISP and C++ standards. -- Served as compiler lab's point person for several HP-UX and MPE-XL system releases, coordinating all language deliverables.-- I was HP's Stanford Recruiting Team Leader for Computer Science for about four years, 1993-1997, and also served on HP's CS recruiting team for Cornell University.

Managed teams of up to 12 engineers responsible for the development, release and support of programming tools on multiple platforms. Products included: CBASIC compiler, C Compiler, linkers, assemblers, and a new debugger. Platforms were CP/M-86 and MS-DOS, as well as new development for Concurrent DOS and Unix on the 80286 and 68000. Other responsibilities:-- Management of contract deliverables to IBM, Motorola and Intel. -- Special assignment as technical recruiting manager, succeeded in growing the company's engineering staff by about 80 people within 3-4 months. -- Implemented a portable strings library in C, using m4 macros as an alternative to templates.

The Advanced Data Institute -- also known as "A.D.I. America" -- was affiliated with the Karlsruhe, Germany, company of the same name.As the first engineering staff member, I hired and trained the software staff for this Sacramento startup dedicated primarily to the support and enhancement of the German-developed DBMS "Aladin." Other responsibilities included -- Extensive cooperation with the German developers. -- Direct support of customers and customer applications. -- Continuing a contract from Chapin Associates, extracted UCSD Pascal compiler from p-System to run as a standalone compiler under a version of Unix. -- English localization.

My second effort at founding an independent company. Besides various consulting projects and dead-ends, I designed, developed and marketed the CPR text formatter for the UCSD p-System.

SofTech Microsystems was a subsidiary of SofTech Inc. dedicated to the commercial development and propagation of the UCSD p-System, under license from the University of California. My job was licensing and marketing, and involved lots of phone calls. To date, this has been my only non-engineering job.

(not affiliated with the university itself) I founded this San Diego consultancy to address the immediate demand for UCSD p-System expertise.-- Consultant to Sperry-Univac Minicomputer Operations, Irvine CA. Design and development of software for Maintenance Processor in new minicomputer system.-- Developed UCSD p-System booter and disk driver for the DEC RX02 disk system (PDP-11 assembly language).

For the UCSD Music Dept, I rewrote an ALGOL application called "PRISM" (Pitch and Rhythm Interactive Synthesizer for Music) in UCSD Pascal and assisted in its deployment to students.

Contributed to the initial public launch of the "UCSD Pascal System" in July 1977, first as an unpaid volunteer and later as a paid staffer. Wrote the initial version of the "Setup" utility, though it was soon replaced, and contributed to the documentation.Ported the UCSD Pascal system to the General Automation GA-16 minicomputer, and was co-author of the p-code interpreter for GA-16. Later consulted on the initial designs of the p-code interpreters for the 6502, 6800 and TI-9900 microprocessors. The 6502 work later became famous as "Apple Pascal". The TI-9900 Pascal was extensively promoted by Texas Instruments as part of the TI-99/4 microcomputer.
