Add Ammar Alakkad as a frontend maintainer for CustomersDot

I started actively reviewing MRs for CustomersDot on Oct 4, 2019. During this time I've learned a lot and worked on bridging many gaps, from being more iterative to taking better care of testing.

Since I began working on CustomersDot in July 2019, I've reviewed over 75 MRs and contributed 150+ merged MRs.

I enjoy collaborating with our UX and backend counterparts, e.g. collaborating with the UX team during Pajama's project.

I'm still working on learning more about advanced GraphQL, learned about smart queries during this review.

Trainee frontend maintainer issue.

Initiatives

• Porting Danger bot from GitLab to CustomersDot
• Suggested and implemented MVP for excluding OOO from reviewer roulette for CustomersDot before the Engineering Productivity team make it official
• Added <code data-sourcepos="16:11-16:24">.tool-versions</code> to facilitate working with asdf.

Links to Non-Trival MRs I've Reviewed

Provided a short review summary under each item.

• Display namespace missing error in addon purchase page

suggestions about consistent default values with prop type, shorten variable names, use v-safe-html with defined allowed tags

• Add additional answers for cancellation

suggestions about using GitLab's utility classes, matching the provided design

• Introduce TransactionLineItem component

suggested merging <hr> within a child component and a prop to control it to reduce code redundancy

• Show add seats button for dotcom subscriptions

Provided a patch to enhance frontend tests, and another patch to fix a feature flag issue for a backend MR

• Add product_radio implementation

Had a suggestion for the UX which got accepted, suggested component-specific style to be in a dedicated .scss file, suggested renaming scss selector to not inherit unwanted styles

• Use Vue.js selects for Sign In/ Sign Up page

Noticed MR removed an id which would break the corresponding label, noticed adding required to a not required field.

Links to Non-Trivial MRs I've Written

• Pajamas: New GitLab.com Subscription Page

Used skeleton component under a feature flag followed by another MR to replaced the placeholder

• Use new gitlab subscription form

Add plumping between introduced change and parent component with a feature spec covering it

• Remove bootstrap-switch from js, scss and dependencies
• Add renew subscription api and payload
• Graduate Pajamas Update: "Manage Purchases" from feature flag
• Add accept terms component and consume it
• Graduate Payment Methods page from feature flag
