How an AI-assisted rebuild took a vibe-coded MVP into production infrastructure a founder could build on.
Hera Fertility had shipped an ambitious vibe-coded prototype that resonated with patients immediately. Growth outpaced the architecture: authentication was stitched across three providers, the database layer was copy-pasted from tutorials, and every deploy was a manual SSH session.
The founder was spending more time firefighting than building features. The tool that started as a weekend project needed to become real software — without tearing up the product that users already loved.
We mapped the existing flows, identified the three systems under the most load, and replaced them one at a time behind feature flags. The product stayed up the entire time — no big-bang migration, no customer-visible downtime.
Every change came with tests, a CI pipeline, and runbooks so the founder could keep shipping once we handed it back.
Consolidated three auth providers into one provider with a thin adapter. Sessions now survive deploys.
Introduced a typed ORM with migrations in version control. Schema changes are now reviewable and reversible.
GitHub Actions runs tests on every PR and auto-deploys to staging on merge. Production deploys are a single click.
Error tracking + performance monitoring + uptime alerts wired into a shared channel. The founder sees issues before users do.
Measured as the founder's weekly shipped-feature count compared to the three months before the engagement.
