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.
Los Angeles is a true hub of innovation in California.
Ideas are flying, projects are launching, and the competition is fierce. Whatever your industry, there is a very high chance your direct competitors are already thinking about their own mobile app. Or worse, they have already launched it. 🚀
In such a crowded market, whoever offers the smoothest user experience wins the game.
In short: innovation is no longer an option,
Many project founders in Los Angeles waste time hesitating. They push back development month after month. But the market in United States does not wait.
You want to launch a digital project in Los Angeles. You meet with developers, and suddenly they are throwing words at you like frontend, backend, APIs, and databases.
You nod your head, but honestly, you are lost.
Forget the technical jargon. Building a mobile application is exactly like opening a restaurant in California. It is a precise mechanism where every single element plays a vital role.
Let's imagine your app as this famous restaurant.
The frontend is the dining room. It is the decor, the tables, the menu presentation, the ambiance. It is the actual app your users download to their phones. This frontend must be beautiful, welcoming, and follow strict standards, like Apple's Human Interface Guidelines. If the dining room is ugly, the customer will not enter.
Next, there is the API. The API is the waiter. The customer gives them their order. The waiter runs to the kitchen to pass on the information, then comes back with the hot plate of food. Without the waiter, the dining room and the kitchen cannot communicate.
Twelve years ago, I launched my very first mobile application. Phones have changed since then, but my job remains the same: turning ideas into concrete tools.
From my office in Cannes, I help entrepreneurs and SMBs design iOS and Android apps that make real sense. I don't just code for the sake of coding. I try to understand your business, your users, and your actual needs.
My goal is simple. Build an application that people will actually want to use every day. The key point: we build for them, not for us. Let's talk about yours.
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.
An app can be built fast and cheap. What costs money is what comes next: code written without structure becomes impossible to change, and the smallest new feature means starting over. Invent Better charges for the work that makes a second version possible — tests, a readable architecture, and code another developer can pick up.
It is entirely possible to build a mobile application extremely fast and for very little money.
All you have to do is ignore every best practice, copy and paste random blocks of code from the internet, and cross your fingers hoping it holds together. On the day of your big presentation in Los Angeles, the app will probably look fine.
But that thin layer of paint will crack almost immediately.
The second you get more than ten users trying to log in at the same time, the system will crawl to a halt. On mobile devices, user patience is brutally short. And slowness is always perceived as a broken product.
If you want your project to succeed in Los Angeles, you have to accept a very counter-intuitive reality: we never build everything you initially imagined.
We always, without exception, start with a Minimum Viable Product. The famous MVP.
What exactly is an MVP?
It is the smallest, simplest, and most direct version of your idea. It is the very essence of your solution. Why do this for your business in California? Because the statistics are brutal. Currently, most app features are absolutely never used by the public.
Why spend your hard-earned budget developing ghost options?
Imagine you want to open a restaurant in Los Angeles. Are you going to borrow millions to build a two-hundred-seat palace with a forty-page menu without knowing if people actually like your cooking? No.
You open a cozy thirty-seat bistro. You cook five dishes to absolute perfection. You see if the customers across your United States walk through the door. If they love it, then you expand.
Nothing beats a concrete example to truly understand. Here is the story of an established service company.
This business had a standard website. Their analytics showed that most their traffic was coming from mobile phones. That is a massive number. But there was a major issue. They were getting absolutely zero bookings from those devices.
Their customers were trying to book appointments, getting lost on the clunky mobile site, and giving up entirely.
The technical challenge was very real. We needed to handle a complex calendar system, secure payments, send push notification reminders, and allow multiple users to coordinate schedules.
The client wanted to build everything at once. A loyalty program, a blog, a forum, and the booking module.
I reminded them of a vital statistic: most app features are never actually used. Why spend thousands of dollars on ghost options?
There is no single price for a mobile app, for the same reason there is no single price for a house. What sets the figure is scope: how many screens, whether it needs a server and user accounts, and whether it ships on one platform or two. A short scoping call is enough to put a real range on your project rather than a brochure number.
You are launching your project in Los Angeles and the very first question that comes to mind is inevitably about the budget.
That is perfectly normal. But asking how much a mobile app costs is exactly like asking how much a house costs in California. A small, functional studio apartment and a forty-room castle are simply not the same project.
Here is what actually determines the budget for a mobile application. 💶
Three main factors influence the cost of your project in Los Angeles:
The real estate market in Los Angeles is fiercely competitive. If a potential buyer misses a great deal because your mobile site was lagging, they will simply go to your competitor.
A great real estate app is the tool that alerts the buyer before anyone else. We set up geolocated push alerts the very second a new property matches their criteria in California.
We add virtual tours using 360-degree photos that are perfectly fluid, with zero endless loading screens. We even integrate real-time mortgage calculators directly linked to your CRM. The key point: we put the entire real estate agency right in the client's pocket.
In the banking world, security comes way before design. But one does not prevent the other.
Building a financial app for United States means respecting heavy regulations like PSD2 in Europe. It means integrating end-to-end encryption to protect every single transaction. It is the digital equivalent of building an armored cash transport vehicle.
You have a single direct point of contact from start to finish. In a large agency, you pay the salary of the sales rep, the project manager, the art director, and finally the junior developer who actually writes the code. With an experienced freelancer, there are absolutely no middlemen. I design, I architect, I code, and I publish. Decisions are made quickly over video calls. This drastically reduces your overhead costs while ensuring that the person who truly understands your business goals is the one typing on the keyboard.
Native means the app is coded specifically for one single system, using Swift for Apple or Kotlin for Google. Hybrid uses a common language, like Flutter, to generate two full apps from one single codebase. Native offers maximum peak performance for heavy gaming or intense tools. But let's be clear, hybrid currently covers most business needs with quality that is totally indistinguishable to the end user. The key advantage of hybrid is financial: you practically cut your project's development time across our United States in half.
Maintenance represents an essential part of your app's overall budget. It covers mandatory iOS and Android system updates, patching security flaws, and adjusting layouts for new screen sizes. Data shows that most users flee if loading exceeds three seconds. Without maintenance, your app slows down and eventually dies. The exact amount depends on the size and complexity of your project. We discuss it together during our first call.
A full technical audit takes exactly one week. You grant me access to your source code and your crash analytics. I comb through every single line of code. I analyze the technical architecture, security protocols, and performance metrics. At the end of this week, I hand you a detailed and highly incisive report. It includes a prioritized list of critical bugs to fix immediately, actionable recommendations, and a concrete repair estimate. It is the mandatory tool to know if your app can be saved or if it must be rebuilt.
That is exactly my working method and the most highly recommended strategy. Knowing that a large share of features planned in advance are never actually used, trying to build everything at once is financial suicide. We launch a Minimum Viable Product (MVP) containing only the three to five vital functions in eight to ten weeks. Then, we analyze how your real users interact with the product. We iterate based on hard data, not wild guesses. This is how you build a true market leader.
Delays range from a quick twenty-four hours at Apple to a mandatory, non-negotiable fourteen days at Google. Apple reviews your code very manually to ensure strict compliance with their design and technical guidelines. Google now forces all brand-new apps to be actively tested by twenty different people for two consecutive weeks before allowing a public release. Be warned, during the holiday season, these delays can easily triple. I anticipate all these bottlenecks so your launch in California happens exactly on the planned date.
ASO (App Store Optimization) is the specific SEO for app stores. It is the exact engine that makes you visible. We optimize your title, subtitle, hidden keywords, and we design highly impactful screenshots. Most importantly, we set up automated strategies to harvest positive reviews. The statistics are brutal: most users read reviews before they even hit the download button. A bad rating condemns you to total invisibility. I guide you through this critical phase so your application is easily found.
Yes, if your users are at risk of losing their cellular connection in a basement, on the subway, or while traveling abroad without roaming data. Offline mode securely stores essential data directly on the phone and syncs it silently the second the network returns. You must anticipate this. The key advantage is a totally frictionless experience, but adding it after launch easily costs three to five times more than planning it in the initial architecture. Let's discuss your users' actual field reality to make the right call.
I handle the entire update workflow for you. Every new version must go back through the meticulous review process of both Apple and Google. You need to plan for a minimum of four to six serious updates per year. Every single version includes fixing minor issues reported by your users, rolling out your new ideas progressively, and adapting to the latest privacy laws in United States. They click. They quit. They forget. To retain your audience, your application must always be flawless and actively alive.
A responsive website visually adapts to the size of the screen, but a mobile app is physically installed in the core of the phone. The major functional differences are colossal. An app allows you to send push notifications, operate totally offline, use facial recognition for instant login, and access the camera or GPS with extreme fluidity. If you just want to broadcast information, a website is enough. If you want to create fast, daily interaction, you need an application.
