v0 · to production
Your v0 app, taken to production.
Taking a v0 app to production is a different job from building the prototype. A v0 build gets you polished React screens fast, and that is usually where it stops: the backend, the data model and the parts real users lean on are still to be built. If you are looking to hire a v0 developer who finishes what the builder started, this is what that looks like: senior engineers keep what you validated, add sign-in, payments, a data model and deploys that hold, and ship it to real users.

01 · What breaks
The v0 prototype works for you. Then real users show up.
What founders bring us after a v0 build, in their words. These are not v0’s faults; they are the parts of a product no builder can finish for you.
- Auth and roles
Anyone can see anyone’s data.
The prototype has a login, but every signed-in user can read every row. Roles, ownership checks and sessions that expire are the first thing real users need and the last thing a demo shows.
- Payments
The checkout works until a webhook fails.
A payment button is not a billing system. Refunds, disputes, failed cards, tax and the webhook that marks an order paid when the browser has already closed all have to be right, every time.
- Data model
The data model was decided by the first prompt.
Tables named after screens, no constraints, and relationships the app enforces only in the UI. It holds for one user and comes apart when two edit the same record.
- Deploys
There is no way to deploy except from the builder.
No environments, no migrations, no rollback. A change that breaks production has to be fixed in production, and the only backup is whatever the builder keeps.
- Security
Secrets are in the client.
API keys pasted into front-end code, no rate limits, no audit trail, and an admin page anyone can guess the URL to. It is fine for a demo and not fine with strangers’ data.
- Store review
The store rejected the mobile build.
A prototype that wraps a web view, has no privacy labels and no reviewer account comes back from App Store or Play Store review. The fix is usually in the backend, not the screens.
02 · What we do
Keep what you validated. Build the parts a prototype leaves out.
The v0 build is the spec. We read it, decide with you what survives, and put real foundations under it.
01Review
A written gap map of your prototype
We walk the app with you and write down what works, what is wired to nothing, and what production demands: sign-in, data, payments, deploys, security, stores. The map is yours either way.
The Production Gap Review02Auth
Sign-in and roles you would trust with a stranger’s data
Sessions that expire, roles enforced on the server, ownership checks on every query, and Apple or Google sign-in where the product needs it.
03Payments
Billing that survives refunds and failed webhooks
Stripe with refunds, disputes and tax handled, webhooks that are idempotent, and receipts that state exactly what the card was charged.
04Data
A data model with constraints and migrations
The schema the product actually needs, enforced in the database, with migrations you can run forward and back and a backup you have seen restored.
05Deploys
Hosting with environments, rollback and monitoring
A repository you own, a build pipeline, staging and production, error reporting, and a rollback that takes minutes instead of a rebuild.
Launch Engineering06Mobile
App Store and Play Store review, handled
When the product needs an app, a real iOS and Android build on managed pipelines with privacy labels, a reviewer account and the listing prepared.
Mobile app development
We never rebuild a v0 app from scratch to suit ourselves. The written plan says exactly which parts we keep and which we replace, and why.
03 · Proof you can check
Prototypes we took to production, including our own.
Several of our own repositories began as scaffolds in an AI app builder, so we know where the line is from the inside. A stalled hand-off MVP we rebuilt and now operate, and a client platform built on the foundations a prototype is missing. Every figure opens its receipt.

How we countThe work behind the numbers
The number
v1.0.4 SkillSchedule’s iOS and Android app, built on Expo alongside the web portals
- Venture we operateTriaPetA hand-off MVP whose own README said every phase was incomplete, rebuilt into a referral platform with real-time routing, portals for owners and clinics, a mobile app on one API, and measurement honest enough to tell us what to fix next.
- ClientSkillScheduleParent, coach and admin portals and an Expo app on one API, with Stripe billing that splits refunds, Apple and Google sign-in, push notifications and crash reporting, built for App Store and Play Store review.
- We start where many founders start: several of our own web front-ends and product prototypes began as AI-builder scaffolds before our engineers took over.
04 · In their words
Clients on the work, word for word.
Names and titles attached. When someone also has a business tie to our founder, it is disclosed under the quote.
Synaptech built a solid food delivery app that works well for our business. The ordering system is straightforward and our customers find it easy to use. Good communication throughout the project.
Darren McAdamsLinkedInFounder · FoodJetsDisclosure Darren is also Veer’s co-founder at Craveble, a venture we co-operate, and the two work together at American DVBE. Synaptech developed a project management system that helps us track our civil engineering projects more efficiently. The reporting features are useful and the interface is clean. They delivered on time and stayed within budget.

05 · How it starts
Read the prototype first. Then foundations. Then launch.
The same order every time, because each step protects the next. You see the plan before we start and the product on a real URL before it goes to users.
Every line of code we ship runs on one rule: AI drafts, senior engineers decide. How we build →
Step 1: The free Production Gap Review
Share the v0 project or a link to the running prototype. We walk it together, then hand you a written gap map across sign-in, data, payments, deploys, security and store readiness.
Out a written gap map, yours to keep
Step 2: A written plan
If there is a fit, you get a written plan with the scope, a timeline and an estimate: what we keep, what we rebuild, and why. If there is not a fit, we say so.
Out scope, timeline and an estimate, in writing
Step 3: Foundations
A repository you own, the data model with migrations, sign-in and roles, and hosting with staging, production and rollback, before any screen gets its polish.
Out your repo, your hosting, roles under test
Step 4: Money and integrations
Stripe with refunds and disputes, idempotent webhooks, email and SMS, and every third-party key moved out of the client, with tests on every path that moves money.
Out money paths under test
Step 5: Launch and after
Error reporting, a tracking plan, store submission when there is an app, and a first report on what users actually do, so the next step is a decision rather than a guess.
Out live, monitored, measured
06 · Straight answers
Questions founders ask about a v0 app before launch.
Can you take my v0 app to production without starting over?
Usually, yes. A v0 app typically arrives as a strong front end with little or no backend behind it, so the screens survive and the system underneath gets built. The review maps which parts survive as they are, which get rebuilt behind the same screens, and which are missing entirely. We keep what you validated and replace only what production demands, and the written plan says which is which before anything changes.
Why hire a v0 developer instead of asking the builder for more?
The builder is good at the part it does: screens, flows, a first version of the logic. Sign-in you would trust with a stranger’s data, payments that survive refunds, a data model with constraints, deploys with rollback and store review are a different job. A v0 developer who has done that job finishes the product; more prompting mostly produces more screens.
Do I keep my code?
Yes. The first thing we set up is a repository you own, with the build pipeline and hosting in your own accounts. If we part ways, everything keeps running without us and the next team has a codebase, not a dependency on a studio.
What does this cost?
The review is free and ends with a written plan that carries the scope, a timeline and an estimate for your app, not a package. We do not publish prices because no two prototypes are missing the same things. You see the plan before you commit to anything.
Will it work as a mobile app too?
If the product needs one, yes. We build iOS and Android apps on Expo that share one API with the web, and we handle App Store and Play Store submission with the privacy labels, reviewer account and listing prepared. A web view wrapped in an app usually does not pass review, so the plan says what a real app needs.
How do you use AI yourselves?
Across the build, under one rule: AI drafts, senior engineers decide. Several of our own repositories started as scaffolds in an AI app builder, so we are not snobbish about where a product begins. A senior engineer reviews and owns everything that ships.
07 · The front door
Find out what’s between your v0 app and production.
Share the project or just the link. Leave with a written gap map across sign-in, data, payments, deploys, security and store readiness, before you spend a dollar. If we’re not the right team to close the gaps, the map is still yours.
