Case Studies in Agency Dev

Background

In 2016 I began working as a developer for Crometrics. The company specializes in A/B Testing and development of high performing UI and UX. Over the years, I’ve developed frontend experiments in multiple JS frameworks and delivered backend solutions when necesssary. Clients range from SAAS, to E-comm, to Enterprise and more.

Highlights of my work:

  • Expert knowledge in UX practices and A/B testing
  • Developing cross-browser mobile-first user interfaces per spec and Figma
  • Feasibility studies and collaboration with the product team
  • Code review and assisting junior developers
  • Providing support through Slack and video calls to technical and non-technical clients

I invite you to take a look at the company case studies and client list. Below I will detail some examples of my contributions.

Feasibility Studies

As a senior member of the team, I’m often called on to determine whether more complex experiments are possible. In this case, I determined the experiment was feasible, but complex. I then created an architectural diagram to explain how the experiment could be implemented.

Example Feasibility Request: During the booking process, if errors occur, pop a modal to allow a user to submit a phone number. Upon submission of the form, an API call would be made, and the form would pass the user’s phone number along with any relevant data from the dataLayer to an agent as preliminary information before reaching out to assist the user with their booking. The API request would trigger the call center agent to reach out and review the data passed. The API key cannot be exposed.

Component Development

One client offered design assets via Storybook to use in their experimentation program. The assets had to be translated into frontend code compatible with our frontend environment, while maintaining the look and functionality of the originals. I created and organized modern stateful components to match their assets and reduced the time needed to build experiment iterations.
