Now I Get It! Blog

Claude's response is never the final answer.

Sometimes, AI-generated web pages contain small errors.

A dropdown now lets customers pick a visual style for their generated page -- Academic Editorial, Vintage Travel Poster, Brutalist, and more.

Adding an admin-only bulk endpoint that uses Anthropic's batch API for cheaper, async processing -- plus the regression review that found a latent bug nobody knew was there, and the 504 that wasn't actually a failure.

A latent CloudFront key-rotation bug went off in test four days before I noticed, and prod was a few hours away from the same fate.

A small UX cleanup with an outsized discoverability win, plus a thumbnail-403 red herring during smoke testing that I attributed to a benign cookie expiry.

The thousand-fold SES headroom that came with production access also opens a real attack surface.

AWS approved SES production access, so the auto-confirm hack from launch night came off and Cognito started sending real verification codes.

Now I Get It!

A general-purpose gift code system whose first job is giving five free credits to the earliest 200 waitlist signups at launch.

Replacing a scan-then-filter DynamoDB query with a sparse GSI and CloudFront edge caching, then measuring what actually improved.

Making translation mode filterable by reusing the tag system instead of building a parallel badge mechanism.

A full audit of the test suite before launch surfaced fixture rot, two real bugs in existing tests, and coverage gaps on the modules added most recently.

Enforcing Anthropic's supported-countries list at checkout without adding a single line of frontend code, by delegating to Stripe.

Adding free-form tags to personal galleries, and why the interesting design question wasn't the feature shape but where to put the data.

Removing a pre-user-accounts safety valve that credit-based pricing made redundant, and enjoying the rare pleasure of a PR that's almost all deletions.

Replacing sequential Lambda updates with an atomic alias flip, and the five bugs that only showed up when I actually ran the new deploy script end to end.

Adding an SQS queue between upload confirmation and PDF processing, sized against real production data, with retries that don't block other jobs.

A staleness detector from the previous day's queue refactor was declaring long-running papers dead at 5 minutes because nothing was updating the progress timestamp while Opus was streaming.

Building an admin dashboard for reviewing copyright takedown requests, then a public status page so reporters can track what happened -- closing both sides of the takedown workflow.

Refactoring two 500-line deploy scripts into modular subcommands -- because waiting through a Docker build to change an HTML page is nobody's idea of fun.
