A single prompt can't safely refactor a multi-file codebase. Here's how repo-scoped slash commands and staged subagents in Claude Code fix that, with git safety gates included.
A field guide to diagnosing V8 memory leaks and event loop lag in high-throughput NestJS APIs — measuring lag with perf_hooks, killing RxJS subscription leaks, and offloading CPU work to worker threads.
How to wire Stripe's Payment Element into a React app so 3D Secure, Apple Pay, and Google Pay don't leave you with orphaned orders or duplicate charges.
A cost and latency comparison of self-hosted headless ComfyUI against managed APIs like Replicate for Flux and SDXL image generation in web apps.
A practical look at Next.js Partial Prerendering — how to structure Suspense boundaries correctly, why cookies() can silently kill your static shell, and how to stop CDNs from leaking one user's data to another.
Fix slow LCP and INP in React + Vite apps with route-level code splitting, manual Rollup chunks, and smarter icon imports. Real config included.
