Work Experience
Front End Software Engineer
2016 - PRESENT
PagerDuty
- Created reusable UX components which includes a data/time picker, filterable/sortable table, drag and drop interface, and dashboard modules.
- Built an analytics dashboard with customizable modules and filterable data. This includes work with charting libraries such as D3.
- Worked on setting up a websocket server so that certain pages in our app were live in the sense that a user never had to reload the page. The page always had the most up to date data and would change whenever any data would change in the backend.
- Contributed to a UX 2.0 initiative which included re-skinning our entire application. This included animations, hover & active states, new drop downs, new layouts, etc.
- Designed a new user flow for the sign up page which was a trial wizard to get new users more familiar with features as they were setting up a new account. This was a multipage form that included animations and a walkthrough.
- Developed a product walkthrough which would explain features to new users once they arrive on the main dashboard. This walkthrough was a multistep guide that would show users different features.

The Dyrt
- Contributed to the campgrounds rating feature where users can enter a 1-5 star rating along with a description regarding a particular campground.
- Created a framework to build contest pages. This framework allowed admins to upload a few photos and choose from a few layouts on how to display the details of a contest.

- Created a coupon clipping application where users could browse coupons for a given grocery store and clip coupons for future use. Users could then redeem coupons when at the grocery store. This application was both for desktop and mobile where all the work was done with ember.js, HTML, and CSS.
- Built a shopping list feature set where users could add items to a shopping list, mark as in cart, delete, or import items from a recipe.
- Maintained a consistent user experience for both desktop and mobile for both the shopping list and coupon feature set.
- Designed an automated integration test suite that ensured quality of software. This test suite was run before every deploy.
- Developed an automated deploy pipeline where a series of tasks were to be completed before releasing code. This included a passing test run, asset compilation and upload to S3, and reconfiguring the server to point to the latest build.

Experience
The Dyrt
https://thedyrt.com/The Dyrt is a campground review application. As a front end developer, I helped build the review feature, map feature, contest pages, searching and filtering, and a lot of the UI/UX for campground pages.
PagerDuty Operations Command Console

This is a dashboard that gives an overview of your technical operations. I worked on the configuration, UI/UX for both light and dark theme, and drag and drop UX. In this console, you can also focus on certain elements like a service, or an incident in which the other modules will adjust their context to whatever you focused on.
PagerDuty Incident Details Page
