TypeScript, JavaScript, Python, Web, React, Node.js, AWS, iOS, Windows.
Quip is a real-time collaborative document, spreadsheet, and chat application for web, desktop, and mobile. It was structured as a largely independent company within Salesforce until Salesforce acquired Slack in 2021, when it became part of Slack.

- Technical lead for Quip’s slides product. I was responsible for frontend feature development in TypeScript and React with some Python, interfacing with the product and design team, triaging and prioritising external client issues, and reviewing design and code of other team members.
- Developed and reviewed many miscellaneous features across Quip’s core document product, primarily in TypeScript, React, and full stack integration with Quip’s Python server backend.
- Occasionally seen deploying and maintaining Quip’s Windows application.
Attic Labs • Software Engineer • 2015-2018

Attic Labs was an 8-person startup that developed Noms, a novel open source database. It was acquired by Salesforce in 2018.

Google • Staff Software Engineer • 2009-2015
C++, JavaScript, Chrome Extensions, Python, Java.
At Google I spent 5 years working on Google Chrome, the desktop web browser used by billions of people. Most of these were developing the Chrome Extensions platform – installable applications most visible as large buttons on Chrome’s toolbar, where I was a Staff Software Engineer and technical lead for 2013-2015.
- As technical lead, I set priorities and technical leadership for the team, with a focus on security and speed. My approval was required for all new APIs developed for the Chrome Extensions platform.
- Responsible for general maintenance and improvement of the platform itself.
- Interacted with the open source community that is built around Chrome Extensions. These were hobbyist developers though to developers from large companies (including Google), and everybody inbetween.
- Provided design and code review for many APIs across different teams in the Google Chrome organisation and elsewhere inside Google.
- Designed, implemented, and documented several fundamental APIs – for example chrome.storage and activeTab.
- I am co-inventor of patent US9535755B2 based on the synchronisation feature of the chrome.storage API.
My first year (2009) at Google was on Google Wave, the short-lived email competitor. I worked on features in the web frontend (Java / Google Web Toolkit) and backend (Java).
