AI + React Native

AI features in your React Native app.
Shipped, not stuck in review.

We build the AI part of mobile products: streaming chat, camera recognition, voice, on-device models, and the native modules they need. Then we take the app through App Store and Play review.

Direct access to the people building your product. No account managers, no hand-offs.

The phone is the hard part

The AI part works. The app around it does not.

An AI feature is easy to show in a notebook or a browser tab. A phone asks harder questions: streaming over a bad connection, what a model costs per user, what happens offline, what the reviewer at Apple makes of it, and which native module somebody now has to write.

01

Streams fine on wifi, times out on mobile data.

02

The model API key ships inside the app bundle.

03

Token cost per user nobody has modelled yet.

04

Rejected under the App Store rules for AI apps.

One clear next step. No agency maze.

Founding-client pricing. Early partners lock in senior-team rates before they rise. The scope is intentionally visible before the call.

* You have the ranked fix list within two working days; the rest of the week is us fixing what is critical. Sign a Production-Ready or AI MVP contract and the audit is included at no charge. Run it on its own and it stays a paid engagement, up to $1,800, with no obligation to continue.

How the handoff works

Fast where it counts, visible the whole way.

Twenty minutes to a call, forty-eight hours to a price, two days to a ranked fix list. Every one of those is a clock we keep, and you never wait on an agency status report to know where the project stands.

01

Free audit call (20 minutes)

We look at the prototype, the risk you feel, and what “ready” needs to mean for your users.

02

Fixed-price proposal (within 48 hours)

You get a bounded scope, delivery path, assumptions, and a price range worth reacting to.

03

Ranked fix list (2 working days)

On a rescue we start with the audit. Inside two working days you have every problem we found, ranked by user impact against effort, with an estimate on each.

04

Weekly sprints (visible progress and decisions)

Working increments, short notes, and a running list of what is now safer to ship.

05

Handoff and support (optional retainer)

Documentation, context, and a clean next step after launch. Support stays optional.

Work / proof state

Proof comes from shipped work, not polished claims.

We are keeping this section honest until rescue projects are confirmed and approved for publication.

case studies / building

First rescue projects in progress.

Follow the build on LinkedIn. Confirmed outcomes, stacks, and client quotes will appear here when we have permission to share them.

shipped / our own products

Two products we designed, built, and shipped ourselves.

ariex.fit (AI fitness coaching, with camera recognition of gym equipment) and Mira (a mindful photo-journal, live on the App Store) are both React Native and Expo, both ours, both in real users’ hands. Proof of how we build, not just how we say we build.

The team

Small enough to care. Senior enough to own the result.

We bring engineering, QA, delivery, and client operations into one accountable loop, with no mystery handoffs between strategy and the code.

founder / cto

Volod

Founder, CTO, and full-stack architect in one person: designs the system, writes the code, and owns every technical risk call, from the first estimate to the final deploy.

co-founder / development & delivery

Daria

Development, QA, and delivery in one person: took Mira from first commit to a live App Store listing solo, and holds every Dyvertex project to that same before-it-ships standard.

growth lead

Illia

First point of contact at Dyvertex: finds the teams whose prototype is already breaking, works out what they actually need, and gets them onto the audit call with the engineer who will own the work.

FAQ

Useful answers before the first call.

Can you add an AI feature to the app we already have?

That is the work we do most. Streaming chat that survives a bad connection, camera and vision features, voice, retrieval over your own data, and moving the model call off the device where the API key does not belong. We start with the audit so nobody quotes a number before seeing the code.

Will Apple reject an app because it has AI in it?

Not for having AI in it. Apps get rejected for what sits around the feature: user-generated content with no moderation or reporting path, an age rating that does not match what a chatbot can say, permissions requested without a visible reason, data sent to a model provider that the privacy labels do not declare, and subscription screens that do not spell out what the AI actually does. We prepare for all of those before submission. Nobody can guarantee an approval, and anyone who does is selling you something.

Do you build mobile apps as well as web?

Mobile is the focus: React Native and Expo, including native modules in Swift and Kotlin when a vendor SDK has no wrapper, and App Store and Play submission. We also build the web apps and backends behind those products. See the services pages for the specific scopes.

Do you write tests, or just ship?

Both, and the tests are part of the fixed price rather than a line item you can cut. Unit and integration tests on the logic that is expensive to get wrong, end-to-end tests on the flows that make money, and both running on every pull request so a regression fails CI instead of failing a customer. On mobile that means Detox running from EAS Workflows against a real build before a submission, because a regression there costs a review round. We use AI to widen what gets tested: it generates the real-world cases nobody sits down and writes, like the interrupted upload, the expired session mid-checkout, the retry that arrives after the timeout, the pasted emoji in a name field. A senior engineer decides which of those a real user could actually reach, and the rest are thrown away. What we do not do is chase a coverage percentage.

Do you sign an NDA?

Yes, if that is needed before you share project details.

Do you use AI to build the code?

Yes, deliberately. We use Claude Code, Codex, and GitHub Copilot to move faster through boilerplate, migrations, and test coverage, and to generate the real-world edge cases a person would not sit down and enumerate. What we do not do is skip the parts AI cannot own: architecture decisions, security review, and judgment about what production-ready actually means for your users. Every AI-assisted change ships through senior review, not blind acceptance of the first output. That review step is the whole business.

What if my project is not from Lovable, Bolt, Replit or Base44?

That is fine. We also build products from scratch for people who have never used an AI builder, and take standard web, mobile, backend, and AI projects. The builder list is the entry point, not a restriction.

What size of projects do you take?

Small and medium ones: a single product, owned by a small senior team. We are not set up for large, multi-team enterprise platforms.

Fixed price or hourly?

Core offers are fixed-price. Hourly work is possible for agency subcontracting or genuinely undefined scope.

What happens after the project ships?

You get handoff, documentation, and an optional monthly support path after launch.

Book the audit

Have an AI feature that works in a demo but not on a phone?

Send the repo, the build error, or the rejection notice. We will use 20 minutes to find out whether it is a fix, a rebuild, or a clean no.
