Improved several parts of our internal build+deploy pipeline:

Bugfixes and expanding support for our automated release system. This creates semver ordered git tags to mark new merged changes, that trigger downstream CircleCI workflows. These CircleCI workflows build and store deployable artifacts of products/services (typically docker images)

For deploying to internal and production environments, our team owns an internal webapp that is used by the whole engineering org. This webapp wraps our K8s infra and K8s actions, allowing teams to granularly deploy their services. I contributed to that frontend app, for example: search feature improvements/fixes, as well as security guardrails to prevent deprecated AWS roles being used in production

Implemented a new fleet of slimmer docker images used as CircleCI executors, so that we could pull our images faster from AWS, resulting in faster job startup time

Ensuring that dependencies the app pulls in from the open source npm registry and internal closed source registries are kept up to date

Monitoring web bundles for duplicate dependencies and overall size

Triaging issues where monitoring data failed to funnel into Datadog

Pair programmed with a coworker to enhance the way our consumer search app redirects, such that it prioritizes recent locations the user has shown interest in, instead of a generic map area

Mentored engineers as we added more complexity and features to our top-level search suggest/typeahead UI components

Learned and used lighter weight declarative UI rendering libraries (lit-html) to create robust, feature rich search UI components

Learned Koa and co-authored + maintained a robust Node.js/Koa app that handles server-rendering the new consumer search web application, hosted at https://www.compass.com/homes-for-sale

Created and contributed to several internal npm packages, which followed traditional semver guidelines and publishing practices of npm packages typically seen in open-source

Mentored and gave direction to more junior coworkers as the team grew, and also delegated out reasonable but challenging amounts of work to them

Worked with UX designers and fellow UI engineers to proof out feature asks

Translated Axure wireframes into implemented features

Created and estimated stories, tasks, and subtasks from high level managerial feature asks

Participated in sprint planning sessions to ensure realistic load balancing

Reviewed and gave feedback on pull requests from fellow UI engineers, on a frequent basis

Wrote automated e2e UI tests for features and bugfixes that I implemented

Ensured automated tests were ran nightly, and acted upon when failures were detected

Worked with UX and UI to proof out new ideas for our tech stack, particularly our JS framework and testing framework

Implemented features within a component-based UI architecture, primarily through React-Redux bindings

Worked with UX to create and iterate upon our reusable React components

Assessing feasibility of designs and technical asks

Providing estimates for time given a set of tasks to accomplish

Aid senior developers in building large-scale projects from the ground up

Building responsive websites that work nicely over the big 3 breakpoints - mobile, tablet, and desktop
