REST, gRPC, and GraphQL API design patterns, contracts, and best practices.
2,500 API endpoints in one MCP server without blowing context windows. The Code Mode pattern uses search + execute to cut token cost by 1,000x.
AI agents calling tools via MCP create new attack surfaces: prompt injection through tool responses, credential leakage, and unauthorized execution.
Handle unpredictable JSON in Go: map[string]any, json.RawMessage, type switches, and defensive patterns for shifting schemas.
Production LLM API patterns: streaming, function calling, retries, token budgets, cost optimization, and observability for backend engineers.
Production REST APIs with Spring Boot: JPA, Bean Validation, global exception handling, MockMvc testing, and scalable patterns.
Handler, service, and repository layers. Custom error types. Middleware chains. Health probes. The patterns for Go APIs handling millions of requests.
Five rate limiting algorithms, their trade-offs, how to distribute them across a fleet, and client-side backoff that works.
How a team serving mobile, microservices, and third-party integrations ended up running REST, gRPC, and GraphQL together.
