Pockit Engineering Blog - Stories about development, tech, and tools
Master the security architecture for production AI agents. Learn how to implement OAuth 2.1 delegated auth, scoped tool permissions, MCP gateway enforcement, human-in-the-loop approval flows, and defense-in-depth patterns that prevent goal hijacking, credential leaks, and runaway agent actions.
Master LLM observability for production AI agents. Learn distributed tracing for multi-step reasoning chains, compare LangSmith vs Langfuse vs Arize, implement cost tracking and automated evals, and build the monitoring stack that turns black-box agents into debuggable systems.
Master the art of zero-downtime PostgreSQL schema migrations. Learn the expand-contract pattern, advisory lock strategies, safe column additions, index creation without locking, backfill techniques, and production-tested tooling to change your database schema while serving millions of requests.
A production-tested guide to using LLMs for automated code migration. Covers Angular-to-React, Java-to-Kotlin, Python 2-to-3, COBOL-to-Java patterns, prompt engineering for code transformation, AST-aware migration pipelines, validation strategies, and the real limitations you need to know before betting your codebase on AI.
The complete, production-tested guide to upgrading from Next.js 15 to Next.js 16. Covers the Turbopack-only bundler, the middleware-to-proxy migration, async request APIs, Cache Components with 'use cache', Partial Prerendering by default, memory optimization in containers, and step-by-step codemods for every breaking change.
