Act as senior fullstack engineer to scaffold production apps in Next.js/Remix/SvelteKit, integrate type-safe APIs, implement auth flows with Supabase/OAuth, add real-time WebSockets/chat, full-text search, secure file uploads, monorepo management, and deploy to Vercel/Netlify with CI.
npx claudepluginhub rnavarych/alpha-engineer --plugin role-fullstackIntegrate APIs with frontend applications using type-safe patterns: tRPC for end-to-end type safety, REST client generation (openapi-typescript, orval), TanStack Query / SWR for data fetching, optimistic updates, and error handling.
Implement complete authentication flows: login, signup, forgot-password pages, JWT + refresh tokens, session-based auth, social login (Google, GitHub, Apple), MFA/2FA, protected routes via middleware, and role-based UI rendering.
Set up deployment workflows for Vercel, Netlify, Railway, Render, and Docker. Covers preview environments per PR, database migrations in CI (expand-contract pattern), environment variable validation, health check endpoints, and rollback procedures. Use when configuring deployment pipelines, managing env vars across stages, or establishing rollback runbooks.
Implement file upload flows with presigned URLs (S3, GCS, R2), multipart/tus resumable uploads, Sharp image processing, drag-and-drop UI with progress indicators, server-side MIME validation via magic bytes, virus scanning, and CDN serving. Use when adding profile pictures, document attachments, media galleries, or any user-submitted file feature.
Scaffold production-ready fullstack projects with Next.js (App Router), Remix, Nuxt 3, SvelteKit, Astro, Blitz, RedwoodJS, or Wasp. Covers framework CLI starters, headless CMS options (Payload, Directus, Strapi, Keystone), feature/layer/domain project structures, Turborepo monorepo layout, env var validation, Docker Compose for local services, and dev tooling (Turbopack, Vite, HMR). Use when bootstrapping a new project or auditing an existing one for missing foundations.

Complete fullstack development toolkit: React, Express/FastAPI, PostgreSQL scaffolding with AI agents
5 toxic senior engineers trapped in one plugin. Viktor draws boxes, Max ships, Dennis codes, Sasha breaks, Lena asks why. They argue, roast each other, and somehow deliver excellent technical decisions. Two memory systems: Billy Memory (local ~/.claude/, informal team chaos) + Project ADRs (formal docs/adr/, professional records for git). Team memory never leaks into ADRs. ADRs work without Billy.
