Employment history

Paradigm4, January 2022 to present: Principal Software Developer
Paradigm4 produces an array-based database, targeted at life science applications. I have worked on transaction improvements and a client for our REST API. Work is done in C++17.
Motional, November 2020 to January 2022: Principal Software Engineer
Motional develops software for self-driving cars. I started in the platform infrastructure team, working on middleware to let the various components communicate. Later, I helped design a new runtime framework, managing the various tasks that make up the software stack, and then moved to the team that was created to build that framework. Work was done in C++20, with some Python 3.
Smartsheet, April-November 2020: Senior SDE II
Designed and developed parts of a new product, called Datatables: a zero-management database that was designed to fit into the existing Smartsheet ecosystem. As a senior member of the team, I also participated in design reviews, guided less senior engineers, and helped management pick technical direction. Work was done in Java and SQL. The product, a multitenant SaaS service, is implemented with microservices, based on Micronaut, and runs on AWS Lambda (a serverless application framework). I applied compiler technologies to optimize execution of requests.
Google, April 2011 to April 2020: Senior Software Engineer
My last team at Google was working on a project called Longform, for writing and editing text with a stylus. The library was usable in various contexts; the first released product based on it is an enhancement to the ChromeOS virtual keyboard, to make ChromeOS tablets easier to use without a keyboard. Work was done in C++17, with some bits of C++20, and compiled to JavaScript Webassembly via emscripten.
Before that, I worked on QPX, which is the backend for Google Flights, as well as for many airline and third-party travel sites. QPX searches for flights and fares; it's a vast optimization problem. Some highlights of my work: Work was done in C++11/14 and Common Lisp.
ITA Software, 2008 to April 2011 (acquired by Google)
For a description of my work at ITA, see QPX, under Google, above.
Akamai, 2007: Senior Software Engineer
I worked on making one of Akamai's DNS servers multithreaded. Work was done in C++. I also ran an experiment with writing a DNS server in Erlang.
Endeca, 2004 to 2006: Principal Software Engineer
Endeca (since acquired by Oracle) sold an enterprise information access platform to help people search and analyze their information.
Centive, 2001 to 2004: Principal Software Engineer
Centive sold a platform for calculating complex commission plans for companies with millions of transactions per month.
eCal Corp., 1999 to 2001: Chief Scientist
eCal made Web-based calendaring software: a packaged server for the enterprise space, a hosted service for the consumer space.
Netscape, 1996 to 1999: Principal Software Engineer
I came to Netscape as part of the acquisition of InSoft (see below).
InSoft, 1993 to 1996: Senior Software Engineer
InSoft made enterprise videoconferencing and streaming media systems.
Analysis & Technology, Inc., 1992 to 1993: Software Engineer II
A&T was a naval contractor.
National Science Center Foundation, 1991 to 1992: Software Engineer
The NSCF sold computer-aided instruction software for algebra.
