Writing
Real incidents from my own production systems: the problem, the options I weighed with their trade-offs, what I chose and why. No invented scenarios, no generic AI advice, no listicles. First-hand only.

Not a one-week experiment: how I actually structure work with Claude Code and Kiro CLI on a production side project. Where agents genuinely accelerate, where they don't, the guardrails that make autonomy safe, and what it costs per month.

npm audit flags a vulnerability in a package you never installed and cannot upgrade directly. The options: wait, force-upgrade, override, fork, or accept the risk. How overrides actually work, their sharp edges, and keeping CI honest about lockfiles.

One user logged in, thirteen duplicate rows appeared. A check-then-insert in a Server Component render path raced against concurrent renders, and a swallowed error made it snowball. Where writes actually belong, and the one guarantee that holds.

Why I moved a live Next.js project off Vercel, the options I weighed (stay and pay, OpenNext, static export), what each would cost me, and the DNS, redirect and analytics surprises that only showed up after the switch.

Pulling shared UI into its own package sounds like a weekend refactor. Then Tailwind majors clashed, a deleted brand color kept resurrecting itself, and CI couldn't install the package at all. What distributing a private shared package actually involves.

Two real SSR-mismatch bugs: toLocaleString rendering different number formats on server and client, and an iOS-only flicker from a clobbered html attribute. The options weighed for each fix, and a general method for diagnosing the whole bug class.

I migrated my SEO pages to static generation expecting near-zero compute. Active CPU went up instead. The culprit: default <Link> prefetching multiplying every visitor into dozens of server renders, and why prefetch={false} alone made the UX worse.

My side project hit two free-tier limits in the same week: serverless CPU and database egress. How I found the one query behind most of it, migrated dynamic SEO pages to SSG with client-side infinite scroll, and untangled the three cache layers everyone confuses.

A static, CDN-cached page scored a 5.7 s LCP with a 1.2 s FCP. The largest contentful element turned out to be a deliberately deferred consent banner. Five candidate fixes, their trade-offs, and why the counter-intuitive one (render it earlier) won.

My retrieval returned 200 OK and zero rows, silently. Why raw embedding similarity scores are model-specific rather than meaningful on their own, what real score distributions look like, and how I calibrated a threshold with eval pairs instead of intuition.
