- Established a UI build, release, and bootstrap process, enabling QA to test arbitrary UI versions, and generally making releases more predictable and less scary.- Spearheaded a major new UI feature from initial UX research and interviews to UI and API design and through multiple releases and user feedback. The process established here has set the bar for user-centered thinking for all new user-facing features.- Introduced GraphQL as a middle tier, established the initial schema, and mentored on GraphQL best practices. A huge win here is that the API is more representative of the user’s mental model, but no changes were needed to the underlying data. I love GraphQL :)- Reduced costs for a massively scaled (and critical!) images api by balancing bytes served at the expense of CPU- Daily involvement with a whole host of AWS services like CloudFront, S3, ECS, ECR, EC2, Route53, Cloudwatch, and many others.- Established (and evangelized!) E2E testing strategy

- Architected, developed, lead a team, and deployed a micro front end loading platform for an existing monolithic UI application. Aside from developing the browser application, this included a large amount of deployment work involving AWS, Jenkins, spinnaker, helm, and Kubernetes.- Defined and developed an incremental migration path from the existing large web application UI to individual micro frontends. This was a huge success as we effectively replaced the foundation of our entire UI without affecting any of the (many) UI developers' day to day!

- Architected, planned, and developed the UI platform for the next evolution of Zenoss’s core product: Zenoss Cloud (https://www.zenoss.com/product). This included selection of UI frameworks, libraries, test frameworks, build tools, reusable component library, and broader concerns such as scalability and security.- Scoped, estimated, and planned implementation of UI features, balancing product, user, and technology requirements, ensuring that the resulting features fit neatly within the UI platform- Worked closely with product stakeholders to wireframe and prototype new features and ensure they align well with the broader UI architecture- Worked closely with back end engineers to design (and frequently implemented) GraphQL schemas which properly model the domain and providing maximum flexibility for queries- Mentored fellow engineers (some remote) through white boarding, conversation, and code review, often demonstrating the correct way to “cut with the grain” of a new library- Constantly reevaluated UI user experience, including consistency with style guide and/or design system- Contributed to and troubleshooted Jenkins and Spinnaker CI/CD pipelinesInvestigated complex technical issues across the entire application stack- Presented technical concepts to non-technical people from support to sales to executives

- Developed a variety of data visualization components using D3 and SVG- Designed and developed a number of one-off SPAs, with minimal oversight, and occasionally implemented backend services as needed- Served as an expert in web application development tools, libraries, frameworks, and best practices- Brought my passion for user-centered design thinking to just about every conversation, ensuring the end user encounters as little friction as possible

Burlington, Massachusetts, Us

- Developed the Node.js backend for an automated, cross-platform, mobile testing framework- Developed the JavaScript client for the mobile testing framework- Developed a Node.js CLI tool and SPA for listing agents, executing tests, and viewing results

- Created reusable ad templates and scripts enabling print designers to rapidly deliver digital ads- Designed new digital ad formats and microsites, many of which became new products- Mentored overseas designers via design reviews, broadly improving the quality of deliverables- Proposed, designed, and developed internal tools (SPAs) which saved time and money by reducing errors and replacing legacy software
