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.
Look around you on the streets of Los Angeles.
What do you see in people's hands?
Samsung, Xiaomi, Google Pixel phones.
Android is everywhere. It is the most used operating system in the world.
Your future clients spend an average of 4.8 hours per day on their phones.
The key point is that your business needs to be where the attention is.
In their pocket.
But launching an app on the Play Store is not a walk in the park.
Many companies in United States think having a good idea is enough.
Spoiler: a good idea with bad execution is worthless.
He clicks. He leaves. He forgets.
That is what happens if the app is slow, crashes, or ignores Android guidelines.
Many people think an app is just a website put inside a box.
That is wrong.
Developing for Android means using Google's native tools to create a flawless experience.
Today, Google's recommended programming language is Kotlin. It replaced Java.
It is a modern, fast, and safe language.
For the interface, we use Jetpack Compose. And we follow the strict visual rules dictated by Google's Material Design.
The most important factor is understanding that the Android world is an open ecosystem.
Unlike Apple's walled garden, Android offers immense freedom.
You have access to endless hardware options. You can deeply customize the system behaviors.
You can even distribute your app outside the official Google store if needed.
This is perfect for internal enterprise tools in Los Angeles.
But this freedom comes at a price.
There are over 24,000 active Android device models worldwide.
Small screens, large screens, foldable phones.
The app must adapt to every single one of them, without ever breaking the user experience.
That is the real job of an Android developer. Turning this technical chaos into a simple, smooth interface for your end user in United States.
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.
An app that crashes is a user lost forever.
It is a question of logic. The user does not have time to suffer through your bugs.
In fact, most users uninstall an app following a technical problem.
The most important factor in my process is technical quality.
How do we ensure the app will hold up on the thousands of different Android phones in Los Angeles?
I work with clients everywhere, from France to Canada.
It does not matter if you are based in Los Angeles or elsewhere, the method is the same.
The key advantage is asynchronous and transparent communication.
No need for three-hour meetings that lead nowhere.
We use tools like Slack, Trello, or Jira. You see exactly where I am.
Every week, you receive an update on your Android phone.
You test the new feature directly from your office in Los Angeles.
If there is weird behavior on a specific Samsung model, you report it to me and I fix it.
I manage the entire Google Play Console.
Signing certificates, store descriptions, translation management, store listings.
You do not have to dive into this administrative complexity. You stay focused on your business. I handle the technical side.
It is a partnership. I am here to advise you, not just execute.
If I have to say no to a feature because it will slow down the project, I will tell you. That is my role as an expert.
Let's take a concrete example.
A client contacted me to build a home services booking app, specifically targeting the California area.
The initial problem? The app had to target the general public.
And the general public uses Android. From all brands. At all price points.
The most important factor was managing Android's terrible fragmentation.
The app had to be as smooth on a five-year-old cheap Xiaomi as on the latest Samsung Galaxy S.
I rebuilt the interface using Jetpack Compose, Google's new design tool.
The result? Much lighter and more robust code.
We launched the app in Los Angeles via a Staged Rollout on the Google Play Console.
A large first. We detected a strange crash that only happened on old Oppo phones using Crashlytics.
We fixed it the exact same day. Without the majority of users ever noticing.
Then we opened it to everyone.
The app maintained a 4.8-star rating on the Play Store. And the client was able to expand their service without fearing their servers would melt.
An Android app generally costs noticeably less than its iOS equivalent. The reason is practical rather than technical: Google's development tools are free and more flexible, and the Play developer account is a one-off fee rather than an annual one. The scope of your app still sets the figure — the platform only shifts it at the margin.
Certain industries have everything to gain by favoring a native Android strategy in Los Angeles.
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.
