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 San Diego (1,423,851 residents) and across California. One single point of contact, 12 years of experience, delivery from concept to publication in 8 to 16 weeks.
Let's pause.
Take a breath.
You are not looking for an agency. You are not looking for a code factory. You are looking for a partner.
I am a freelance mobile app developer.
The key advantage: you have one single point of contact from start to finish. Me.
No account manager acting as a buffer. No salesperson selling you impossible dreams. And most importantly, no junior developer hidden in the back room learning the trade on your dime.
Have an idea for the San Diego market or for the rest of your United States? We discuss it directly.
Today, 63% of global web traffic comes from mobile devices (Statista, 2025).
Your future users are already on their phones.
But they are demanding.
Many people think a developer just types on a keyboard in a dark room.
That is not my vision of the job.
Being a mobile expert in San Diego means mastering the product from A to Z.
I handle concept validation.
I think about user experience (UX).
I design the technical architecture.
I develop, test, publish to the stores, and provide ongoing maintenance.
The key point: no context is ever lost.
There are currently over 24,000 active Android device models worldwide (Google, 2025).
Making an app run flawlessly across all those screens requires absolute rigor.
It is not just about making things look pretty.
We must strictly follow Apple's Human Interface Guidelines and Google's Material Design.
The mobile user is on a train, in the street, or on their couch.
They do not want to think in order to navigate.
I ensure your interface is logical, instructive, and immediately understandable for your audience in the California area.
It is a comprehensive craft that demands a global vision of the mobile ecosystem.
This is exactly what I offer to businesses in San Diego.
I build mobile applications the way a craftsman builds a house. With solid foundations.
I've been doing this job for 12 years from Bordeaux, designing iOS and Android apps meant to last. I refuse sloppy work. The key advantage of this method? Your application won't collapse at the first Apple or Google update.
I create clean tools that are easy to maintain and ready to evolve alongside your SMB or startup. Work done with care is a profitable investment for the long run.
I have guided dozens of clients over the past 12 years. And I know exactly what the number one fear is when launching an app project.
It is the fear of losing control.
You hand over your baby, sign an estimate, and then hear absolutely nothing for three months. You become entirely dependent on a technical black box. 🕵️♂️
The key advantage of our collaboration is total transparency.
It is a matter of trust. Even if I am not physically sitting in your office in San Diego, you see absolutely everything that is happening.
To achieve this, we set up simple and highly effective workflows.
I am not an extremist for a single technology.
Technical choices must serve your United States's business goals, not the other way around.
In short: every project has unique needs that dictate the tool to use.
If you are aiming for an ultra-premium user experience with complex animations, we will go with native code (Swift for iOS, Kotlin for Android).
Even though Android dominates in volume, iOS users spend on average 2x more inside apps.
We often need to take special care of this demographic.
But if you need to test an idea quickly in the San Diego market with a limited budget, Flutter is an incredible strategic choice.
It allows us to code once and have an app for both platforms.
I always explain exactly why I recommend a specific approach.
I translate complex tech choices into concrete impacts for you (costs, deadlines, scalability).
No jargon to hide poor decisions.
We define the best technical foundation together before laying the very first brick.
Businesses in San Diego that understand this are already ahead.
Chaos has no place in software development.
For an application to succeed, it needs a strict framework.
The key point: we always start with the specifications document.
It is our moral contract.
We define exactly what the app will do, screen by screen. We eliminate ambiguity.
Next comes development. I do not disappear into a cave for three months.
You get access to the app on your own phone during its creation.
You see the progress in real-time from San Diego.
Then comes the critical step of store submission.
Nearly 40% of first submissions to the App Store are rejected by Apple (Apple, 2025).
Knowing their rules by heart is an absolute necessity.
Finally, the launch is not the end of our relationship; it is the beginning of your product's life.
I stay by your side for ongoing maintenance and future updates.
This is the level of rigour I bring to every project in San Diego.
One day, a startup founder contacted me with a massive document.
He wanted the ultimate app to disrupt his entire sector in San Diego.
Dozens of screens, complex animations, an internal messaging system...
The most important factor was telling him no.
I reminded him that 80% of initially imagined features are never used by real people (Pendo, 2025).
We spent two days dissecting his idea.
We reduced the 50 pages down to just 5 fundamental screens.
The result? The app was developed and published in 10 weeks instead of 8 months.
He was able to test his concept in the market across his United States with real users.
He gathered data, and he pivoted his business model based on reality, not his assumptions.
He saved thousands by avoiding building a useless technical monster.
Businesses in San Diego that understand this are already ahead.
When you hire me for your project in San Diego, you are not simply buying typing time on a keyboard.
You are paying for 12 years of lessons learned the hard way.
In short: you are paying to know what NOT to build.
A bad technical choice at the beginning of a project will cost you thousands in maintenance just a few months later.
It is like pouring the foundation of a house on sand.
Today, 59% of traffic comes from mobile (Statista, 2025).
Your app is often the very first impression a person in the California area will have of your business in San Diego.
It is not an expense; it is your most strategic investment of the year.
I protect that investment by being direct and pragmatic.
I do not give blind quotes, because that makes absolutely no sense.
Every idea is different.

Tech companies need to move fast, but without breaking what already exists.
I perfectly understand the go-to-market pressure for startups in San Diego.
If you already have a complex web platform, the mobile app should not be a squished carbon copy of it.
On mobile, we adapt. We simplify the user journeys.
The key advantage: we offer the user instant access to the vital functions of your software.
We use robust APIs so that data is always perfectly synchronized.
Are you launching a new concept for the 1,423,851 people in your region?
You must be visible.
Be aware that 65% of App Store downloads come directly from search (Apple, 2025).
I develop the application by thinking about its structure for the store search engines from day one.
We launch fast, we measure what works, and we iterate.
Businesses in San Diego that understand this are already ahead.
Communication. With me, you speak directly to the person writing the code. There is no broken telephone with a project manager. Decisions are made quickly. In short: you save time and you do not pay for the overhead costs of a large company.
Never more than 2 or 3 active development projects simultaneously. This is a strict rule. Development requires intense concentration. If I took on 10 projects like some code factories in San Diego, the quality would plummet. I always prioritize excellence over quantity.
I primarily work on a fixed-price basis for well-defined projects, or on a time-and-materials basis if we are in an exploration phase or ongoing maintenance. We lay everything out clearly in a specification document right from the start.
Yes, absolutely. Today, you cannot ignore either platform given the 6.3 billion smartphone users worldwide (Statista, 2025). I develop natively or with Flutter depending on the strategic needs of your United States.
That is exactly why you watch the app grow on your own phone during the creation phase. There is no "black box" effect and no unpleasant surprises at the end. We validate every single step together.
Ready to launch your app in San Diego?
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.
Let's pause. Let's breathe.
In 15 minutes, you will know exactly where to start.
