graphql
GraphQL gives clients exactly the data they need - no more, no less. One endpoint, typed schema, introspection. But the flexibility that makes it powerful also makes it dangerous. Without proper controls, clients can craft queries that bring down your server. This skill covers schema design, resolvers, DataLoader for N+1 prevention, federation for microservices, and client integration with Apollo/urql. Key insight: GraphQL is a contract. The schema is the API documentation. Design it carefully. 2025 lesson: GraphQL isn't always the answer. For simple CRUD, REST is simpler. For high-performance public APIs, REST with caching wins. Use GraphQL when you have complex data relationships and diverse client needs. Use when "graphql, graphql schema, graphql resolver, apollo server, apollo client, graphql federation, dataloader, graphql codegen, graphql query, graphql mutation, graphql, api, apollo, schema, resolvers, dataloader, federation, typescript" mentioned.

idea-maze
Most startup ideas are bad. Not because founders lack creativity, but because they're solving invented problems instead of lived ones. Paul Graham's essays reveal a pattern: the best ideas come from living in the future and noticing what's missing. Schlep blindness hides gold. Organic ideas beat brainstormed ones.

kubernetes
Kubernetes is the operating system for the cloud. It schedules containers, handles networking, manages storage, and keeps your apps running.
