• Took a career sabbatical to work on personal and open-source projects plus some part-time freelance work
• Developed masks—a full-featured, open-source, self-hostable auth framework for Ruby on Rails.
• Contributed to Shopify stores, Wordpress installations, and other basic applications for various clients.

Framework Computers

2023

• Developed features, performance improvements, and infrastructure changes in advance of high-traffic product launches
• Prototyped new e-commerce and content management platforms with a goal of speeding up development and reducing maintenance burden

Shopify

2016–2022

• Formed Shopify's Identity team and led a project to simplify and secure login, signup, and account management processes.
• Successfully migrated over 2 million accounts to a more secure single-sign-on system, along with major internal infrastructure.
• Led the development of the initial Identity service, tooling for integrating with it, and oversaw the complex migration experience, ensuring no major downtime or security incidents.

• Dev ATC paired Shopify developers with a mentor and had them assist with incident management, keeping the CI/CD train running smoothly, and any other developer frustrations related to the largest codebase throughout the work day.
• I facilitated Dev ATC over 5 years—a program that hundreds of Shopify developers participated in. I personally mentored a good number of them.

• Formed another team named "Multi-channel Foundations" with a goal of improving and maintaining integrations with first- and third-party marketing/sales channels.
• Managed and coached the foundations team through several major projects—including a sync service that moved product and order data between Shopify and major channels. The service cut sync times from days to near real-time, removing a major source of customer and on-call frustration.
• Shipped Shopify's GDPR implementation for first and third-party applications. Onboarded 5 major partners to the API. Managed an on-call of ~15 developers.
• Took over management of several multi-channel teams, and coached them through a consolidation of several channel integrations, ultimately shipping a new product with significantly better reviews.

• Joined the CI/CD team, which owned Shopify's build and deploy infrastructure. I participated in the design and launch of a custom merge queue, automated deploy monitoring and rollbacks, Github/Slack integrations, self-hosted github runners, and more.
• Shipped several libraries and UX improvements for simplifying the deployment and monitoring process—took onboarding to CI/CD from a multi-step process down to just a few clicks.
• As primary on-call for anything related to Shopify CI/CD, I participated in many incidents which often required some form of intervention to roll out or fix problematic changes.

Vantage

2015–2016

• Led the design and development of new product features, directly contributing to the company's first $100k MRR milestone.
• Collaborated with customers to identify needs, designed solutions, and implemented nearly all frontend code, alongside key backend APIs.

Freshbooks

Lead Developer

2010–2015

• Introduced an auth service for sharing session status across the frontend, paving the way for single-sign-on and new REST APIs for expensing, time tracking, and invoicing.
• Led a team that introduced Ember.js, rewrote large portions of the frontend to use it, and modernized the FreshBooks frontend.
• Ran tech talks and workshops on developing frontend with JS and Ember.js.

• Tech lead of a QA automation project that introduced Selenium to FreshBooks. Eventually used by the whole QA team to speed up easy-to-automate manual testing.
• Brought automated testing to large portions of the codebase by refactoring o modern Symfony components—introduced a templating language, HTTP router, request context, and abstractions for managing permissions.

• Developed product features and improvements including VAT support, updated expense tracking, importing/exporting features, and more.

Freelanced since my early teens, designing and developing websites, content management systems, backend integrations, and e-commerce platforms. Have at various points held long-term contracts with local advertising and design agencies.

Early on I developed an ORM and a few other libraries for a now-defunct PHP framework named Kohana. Nothing I've made since has been as popular, but I have contributed to open source efforts at most companies I've worked at.
