One single point of contact, from concept to publication. 12 years of experience. 15+ apps delivered.
In short: I build iOS and Android apps for clients in Los Angeles (3,979,576 residents) and across California. One single point of contact, 12 years of experience, delivery from concept to publication in 8 to 16 weeks.
You want to launch your app.
Spoiler: Apple is not waiting for you.
Apple processes 100,000+ app submissions per week.
And behind this review process, there are real humans clicking, testing, and judging your work.
The key advantage of this strict process is credibility.
When your application is live on the App Store, it is a massive quality guarantee for your clients in Los Angeles.
It proves that you respect privacy, that your interface is clean, and that the experience is smooth.
But nearly one submission in four is rejected.
A hidden crash. A misplaced icon. A button that does nothing.
The iPhone user is unforgiving. They click. They quit. They forget.
And Apple is even stricter.
iOS development is not just coding for a different phone.
It is adopting an entire philosophy.
Apple's philosophy.
Apple controls everything. The hardware (iPhone, iPad) and the software (iOS).
The key point is that this strict control is a massive strength for us.
Unlike Android, where we have to test on thousands of different screens, the iOS universe is much more constrained.
This allows us to achieve an exceptional level of polish for every screen of your application in Los Angeles.
To code, we use the official languages: Swift and SwiftUI.
SwiftUI is Apple's modern standard. It is clean, fast, and built to create smooth interfaces.
But code is not everything.
A good iOS app must respect Apple's Human Interface Guidelines.
This is the design bible at Apple.
It dictates the size of buttons, how menus should open, and the margins to respect.
Why does this matter?
Because iOS users spend 2x more in-app than Android users.
They pay more, but they demand a perfect experience.
If your app does not look like an Apple app, the user will feel it immediately.
They will be confused. They click. They quit. They forget.
My job as an iOS developer is to melt your idea into this premium mold.
We create a product that feels native, natural, and reassuring for your target audience in Los Angeles.
Based in Cannes, I work with clients all over France and internationally. But distance changes nothing about my level of commitment.
For 12 years, I've been creating iOS and Android apps for SMBs and startups by putting human connection first. I immerse myself in your projects as if they were my own. You have my direct number, we call each other when needed, and we move forward together.
The most important factor for a successful application comes first from a great human relationship. That is the core of my approach.
The economy in Los Angeles is evolving fast. Very fast.
Local businesses can no longer settle for a basic, aging website. Digital transformation is happening everywhere across California. And mobile devices have become the absolute center of this shift. 🚀
In short: your clients live with their phones in their hands.
It is an unavoidable reality that most global web traffic comes from mobile devices. If your business in Los Angeles is not easily accessible on their home screen, it is practically invisible to a massive chunk of your audience.
I help companies build this vital digital presence. Governments across United States are pushing small and medium businesses to adapt to these new consumer habits, and funding digital growth.
The observation is the same everywhere. The residents of Los Angeles want to order, book, or find information with a single tap, whether they are on their couch or commuting.
Los Angeles brings a lot of media and entertainment work, where the app is one piece of something larger and the brand is already fixed. That is easier than it sounds: when the design language exists, the arguments about colour and type never happen, and the whole conversation stays on what the thing actually does.
It brings its own discipline, though. A brand built for print and film does not always survive contact with a phone. Type set at a weight that looks elegant on a poster can be unreadable at arm's length on a bright screen; a palette with beautiful low-contrast pairings can fail basic accessibility; a logo designed for a title card does not shrink to a tab bar icon. My job on those projects is often to protect the brand from a literal translation of itself, and to propose the smallest adjustments that keep the identity intact while making the screen usable.
Media projects also tend to be heavy with video and images, which is where mobile performance is actually won or lost. Full-resolution assets on a list view make an app that stutters and a data plan that evaporates. The work that matters here is invisible: resizing on the server, loading progressively, caching properly, and never blocking the interface while something downloads. It is unglamorous, and it is the difference between an app people keep and one they delete after a week.
The nine-hour gap means our working days do not really meet — your morning is my evening. That works well with a rhythm of weekly deliverables you review at your desk and I act on overnight, and it works badly with a project that needs live back-and-forth to move. If yours is the second kind, someone in your timezone will serve you better and I will say so rather than take the work.
Invent Better starts by removing, not adding. An app that does one thing properly ships in two months; one that does five things halfway never ships at all. Given that a large share of features planned in advance are never actually used, the useful question is not whether a feature would be nice, but whether anyone still uses the app without it.
Running an app on iOS requires precision.
The key advantage of native development is full access to the phone's capabilities.
No middlemen. No slowdowns.
The main engine is Swift.
A robust programming language that guarantees maximum performance.
Coupled with SwiftUI, we build the interface for your project in Los Angeles.
This is what gives Apple applications that magical feel: smooth transitions, instantly reacting buttons.
If your app lags, the user deletes it.
They click. They quit. They forget.
That is why I always favor the tools provided directly by Apple.
To manage complex data flows, I use the Combine framework.
It is the conductor that ensures your application's information displays without delay.
Publishing an app with Apple requires anticipating their strict rules.
Spoiler: we do not discover the constraints at the end of the project.
The key point is to prepare the groundwork from the start.
First, the design.
We validate together that your idea respects Apple's guidelines for your target audience in Los Angeles.
Then, the administrative steps.
You need an Apple Developer account. And a DUNS number to open it under your company name.
While the paperwork processes, I develop.
This is the intensive coding phase in Swift and SwiftUI.
Very quickly, we move onto TestFlight.
This is Apple's app that allows you to install test versions on your own phone.
We can even invite your first testers in Los Angeles to gather their feedback before release.
Next comes the App Store Connect stage.
This is the dashboard where we configure your App Store listing.
We must fill out the privacy labels (what the app tracks or not) with surgical precision.
Finally, the submission.
Know that nearly one submission in four is rejected.
If this happens, do not panic.
We analyze the Apple reviewer's feedback, fix the blocking issue, and resubmit.
We move forward step by step until the official publication.
The healthcare sector demands absolute rigor.
Here is a case that comes up often: a connected medical tracking app.
On iOS, health has its own ecosystem: HealthKit.
The goal was to synchronize Apple Watch data (heart rate, sleep) with a simple and secure patient interface.
The key advantage here is the data protection offered by Apple.
We built a completely native architecture in Swift.
Security and privacy had to be flawless to pass the App Store review.
Apple is extremely strict about medical apps. nearly one submission in four is rejected, and this number is even higher for healthcare.
So we bulletproofed the permissions and the privacy questionnaire on App Store Connect.
The application was tested intensively via TestFlight by a small panel of patients.
The result?
Apple approval secured on the first try.
Today, the app holds a 4.8/5 rating on the App Store, driven by the ultra-smooth experience typical of iOS.
This is the level of excellence I apply for my clients in Los Angeles.
A native iOS app generally costs noticeably more than a web or hybrid equivalent. The reason is Apple's standards: its design rules demand care on every screen, button and animation, and App Store review rejects what does not meet them. That extra cost mostly buys a smaller chance of being rejected.
This is the question everyone in Los Angeles asks.
Let's be clear: a native iOS application generally costs noticeably more than a web or hybrid app.
Why?
The most important factor is Apple's high standards.
Apple's design rules require special care for every screen, every button, every animation.
We cannot cut corners.
Then, there is the preparation for the Store.
nearly one submission in four is rejected.
To avoid this, I spend time ensuring the code is perfect, privacy policies are clear, and all crashes are resolved on TestFlight before publishing.
This preparation and quality time comes at a cost.
Excellence requires work.
There are also Apple's fixed fees.
It is not just about coding an app.
The most important factor is using the phone's strengths for your business.
The iPad and iPhone are the ultimate reading screens.
If you offer exclusive content, iOS users spend 2x more in-app than Android users.
Selling subscriptions through Apple's native system is the best way to retain readers in Los Angeles.
The iPhone has the best augmented reality sensors on the market (ARKit).
Placing virtual furniture in a living room, or taking a 3D apartment tour becomes incredibly smooth.
It is a guaranteed wow effect for your clients.
Apple Wallet passes are magical.
The client buys their ticket, and it goes straight into their Wallet app, with a QR code ready to be scanned at the entrance of your event in Los Angeles.
No more digging through emails.
We simplify the user's life as much as possible.
One condition and three criteria. The condition is frequency: an app lives on a home screen, and an icon opened once a year never pays for itself. If your customers come back weekly, one criterion out of three is then enough — it uses the phone itself, it has to work with no network, or it has a legitimate reason to bring people back. Otherwise a website does the same job for less, and I will say so.
An app idea cannot be patented as such; what can be protected is the name — a registered trademark — and the code, covered by copyright from the moment it is written. In practice the risk is almost never theft: it is taking six months to ship while someone else takes two. If it worries you, a non-disclosure agreement can be signed before the first call, without difficulty.
No, and starting without one is healthier. Scoping is about what the app does and for whom; the styling comes after, and it comes out better once the screens are known. If you already have an identity, we use it. If not, the first version can be plain and legible — which is not a fallback: plenty of apps would be better off staying that way.
Yes, and it is often the best money in the project. Clickable mockups put in front of ten people reveal in a week what a three-month build would reveal too late. You see where people hesitate, what they cannot find, what they do not care about. It is also what lets you remove features before paying for them rather than after.
Yes, always, and this is the one point I do not bend on. Both accounts are paid and created under your company's name; I work on them with delegated access. An app published under a provider's account is an app you do not control: you can neither update it nor transfer it without them. Apple's side takes a while to set up, so start early.
As late as possible. A sign-up screen on opening is the first cause of abandonment: the person has seen nothing yet and you are already asking for something. The good rule is to let them try, then ask for an account when it becomes useful — to find their data on another device, to pay, to be recognised. Plenty of apps gain users simply by moving that screen.
The simple rule: collect only what you actually use, say so plainly, and let people undo it. In practice that means a readable privacy policy, consent asked at the right moment rather than in one block at launch, and a way to delete an account from inside the app — Apple requires it. The privacy labels on both stores also have to match what the app really does.
Yes, and there is a rule to know before building a business model on it: anything consumed inside the app goes through Apple's or Google's payment system, which takes a commission. Selling a service consumed elsewhere — physical work, a delivered order — is charged normally. The difference is not a detail; it changes the price you need to display.
Nothing. No specification, no deck, no fixed budget. Thirty minutes is enough if you can answer two questions: who is going to use it, and what does it save them. If you have screenshots of apps you like, bring them — showing what you like is faster than describing it. The rest is my job to ask.
Three signals, and I say them on the call rather than in the third month. If nobody on your side can answer my questions during the build, it will not move. If the budget covers the build but nothing of the following year, the app will die quietly. And if the goal is to reassure an investor rather than serve a user, a mockup costs a hundred times less and does the same job.
Ready to launch your app in Los Angeles?
You have the idea. You know your market in California. Now, it is time to take action.
But not just in any random way. The key advantage of working together is absolute clarity. I will not sell you useless features. I will not make empty promises that I cannot keep.
In 30 minutes, you will know exactly where to start.
Book a free call →30 minutes to start your project
Book a free call →Most of my projects run remotely, and in practice that changes very little. We talk over video whenever you need to, not only at major milestones, and you can reach me with questions at any point during the project — I always answer.
Once we are working together, travelling to meet you on site can absolutely be arranged if your project calls for it. Travel costs are quoted separately, upfront and with no surprises.
