Claude Code moved my recipe app from Drizzle and Neon to Prisma ORM, Prisma Postgres, and Prisma Compute. The database migration worked, but setup and deployment needed hands-on help.
Next.js 16 makes Turbopack the default bundler. The build is genuinely faster, but the edges show. Three real upstream bugs I ran into upgrading a Pages Router app: a runtime assetPrefix that never hydrates, pino breaking the build, and a dev-only hydration regression.
Adding deadline reminders to a workflow tool: a Cloud Scheduler → Cloud Tasks → worker pipeline, why IAM run.invoker was the wrong lock for a public SSO-gated Cloud Run app, verifying OIDC tokens in-app instead, making retries idempotent, computing Japanese business days without hardcoding holidays, and a Next.js standalone build trap with Google client libraries.
When Slack SSO works for staff but not guest accounts: adding Google sign-in as a gated fallback, re-keying users on email, preserving Slack mentions for users who never sign in with Slack, and enforcing who may use which door.
A new design draft and a fresh requirements list arrived mid-build. How I triaged them against priority, deferred the integration-heavy features without stalling, kept the plan doc as the source of truth, and decided the schema was finally stable enough to stand up the database.
