Teck Stacks: Vue, Nuxt, Typescript, Vuex, SCSS

Some of the challenges:

1. Performance Optimization: The profile page experienced poor page load times (over 5 seconds) due to large amounts of images, client-side logic, and API calls.

2. Server Side Rendering: For SEO, we needed to statically pre-render the profile page. However, handling state hydration and middleware in Nuxt SSR proved complicated. 

- On the server, we made API calls to fetch profile data and pre-rendered the page with the response

- On the client, we hydrated the page with the same API response to avoid mismatches

- We implemented Nuxt middleware to match API caching behavior between server and client
