Essays on engineering systems, product craft, and lessons from shipping ambitious software with founders and teams.
SecurityNext.js shipped security releases on 14 October, 27 October and 3 November 2026. A dependency policy that turns those advisories into a routine instead of an incident.
PerformanceNext.js shipped a bundle-optimizer agent skill and new Bundle Analyzer tools. A workflow for using them that produces smaller bundles rather than just more diffs.
ArchitectureNext.js 16.4 recommends Cache Components for every app, enables them by default in new projects, and adds next upgrade --agent. Here is a migration order that does not stall.
ArchitectureReact 19.3 shipped on 9 September 2026. View Transitions and Fragment Refs are stable, Trusted Types are supported, and Server Components can render Context directly.
Product StrategyMost estimates fail in week three, not at the quote. A practical scoping method that keeps the number honest without freezing the product.
Product StrategyThe rate gap between a freelancer and an agency is real, but it is not waste. Here is what the difference buys, and when you should pay for it.
ArchitectureRSC is the default in Next.js 16. Half-adoption is worse than not adopting at all. The numbers, the pitfalls, and the patterns that survived on production apps.
Artificial IntelligenceBy May 2026 the field consolidated to five agents. SWE-bench Pro scores, cost per developer, and the governance gap most teams are ignoring.
PerformanceSame edge function deployed on both platforms for a quarter. p50/p95/p99 numbers, pricing at 14M requests/day, and where each platform wins.
