This is a pnpm monorepo whose dominant application is apps/portal, a Next.js + tRPC + Prisma community platform for tech interview preparation. It delivers three interactive products: an anonymous salary/offer comparison tool with percentile analysis and currency conversion, a resume review system with PDF uploads, comments, stars and gamified badges, and a crowdsourced interview question bank with voting, full-text search and list curation. Authentication is NextAuth via GitHub, file uploads use Supabase storage, and all application logic is exposed through a tRPC router tree backed by PostgreSQL. apps/website is a Docusaurus static site that publishes the interview handbook content, blog posts and practice lists such as Grind 75; it is content-delivery rather than dynamic. The repo has some data/research flavour because it ships Prisma seed datasets (countries, states, companies, salary XLSX) and offer-analysis logic, but those are reference data and application features, not an analytical pipeline. The engineering follows T3 conventions: Zod-validated routers, React Hook Form, a custom UI kit and shared config packages. Strong reusable pieces include an accessible typeahead, a compound radio list, a currency exchange utility and an optimistic vote hook. Weaknesses are long and repetitive tRPC routers (especially the offers-profile update mutation), duplicated voting mutations across routers, inconsistent use of protected routers, hardcoded assumptions in seeds, and no visible automated test suite. The repository is actively maintained with recent commits and CI workflows, but it has medium technical drift: the portal pins older major versions of Next.js, tRPC and React Query, and it depends on a custom vite-plus toolchain. The Prisma schema has many 2022-era migrations and substantial complexity. It is best used as a reference architecture for building community-driven interview-prep features and as a source of isolated UI/utility patterns rather than as a drop-in application.

This repository is the Front End Interview Handbook, a comprehensive collection of front-end interview questions and answers covering HTML, CSS, JavaScript, system design, behavioral topics, and company-specific experiences. It is built as a static documentation site using Docusaurus 3, with a custom theme that includes sidebar advertisements and a modified table of contents. The site supports 10 languages through i18n and is deployed at frontendinterviewhandbook.com. While primarily a content repository, it demonstrates solid software engineering practices in its Docusaurus configuration, custom theme components, and multilingual setup. The content is curated from the h5bp/Front-end-Developer-Interview-Questions repository and community contributions, with references to authoritative sources. The repository also includes blog posts and success stories. It is not a traditional application or data pipeline but a hybrid of a documentation site and a curated knowledge base.
