2. Technology Stack Selection

// Stack recommendation engine
const recommendStack = (requirements) => {
  const stacks = {
    'enterprise-web': {
      frontend: 'Next.js + TypeScript',
      backend: 'Node.js + Express',
      database: 'PostgreSQL',
      cache: 'Redis',
      auth: 'Auth0',
      hosting: 'AWS/Vercel'
    },
    'startup-mvp': {
      frontend: 'React + Vite',
      backend: 'Node.js + Fastify',
      database: 'PostgreSQL + Prisma',
      auth: 'Supabase Auth',
      hosting: 'Railway/Render'
    },
    'high-performance': {
      frontend: 'SolidJS',
      backend: 'Go + Fiber',
      database: 'PostgreSQL + Redis',
      queue: 'RabbitMQ',
      hosting: 'Kubernetes'
    }
  };
  
  return selectOptimalStack(requirements, stacks);
};
