12 years of experience. 15+ apps delivered. One dedicated point of contact.
In short: I build iOS and Android apps for clients in London (8,982,000 residents) and across England. One single point of contact, 12 years of experience, delivery from concept to publication in 8 to 16 weeks.
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.
London is a true hub of innovation in England.
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 London waste time hesitating. They push back development month after month. But the market in United Kingdom does not wait.
You have made the decision to launch your digital project in London. You start reading articles online to understand how to get it done.
And right away, you hit a wall of technical jargon: native app, hybrid app, web app. You have no idea what to choose for your business in England.
Let's sort it out.
Let's start with the native app. This is the luxury solution. We use the official languages created by Apple (Swift) and Google (Kotlin). The result? Maximum performance and total access to every sensor on the phone, like GPS, the camera, or Bluetooth. It is perfect for a 3D video game or a highly complex app. But it is expensive, because you literally have to build two separate applications, one for each phone ecosystem.
Next, the hybrid or cross-platform app. This is where technology has taken a giant leap forward. With tools like Flutter, we write a single codebase that runs on both iOS and Android simultaneously. You keep most the native performance, but your budget and development time are cut in half.
London is one hour behind me, which in practice means we work the same day — a question at ten is answered by eleven. It is the closest thing to working with someone in the same office that remote work allows, and it is why most of my English-language projects have been British ones.
That overlap is worth more than it sounds. On a project spread across a real timezone gap, a single misunderstanding costs a day: you ask, you wait, you get an answer that reveals a second question, you wait again. With London, the same exchange happens over a coffee break. Over a three-month build, that difference is not a convenience, it is several weeks of calendar time that never get lost to waiting.
London projects tend to arrive further along than most. People have usually done market research, sometimes have a designer already engaged, and often have a clear view of who the app is for. That makes my job narrower and more useful: not deciding what to build, but saying honestly what each part costs, which pieces can wait, and where the design as drawn will fight the platform rather than work with it.
The one thing worth settling early on any UK project is where the data lives and which rules apply to it. Since the UK left the EU it maintains its own data protection regime alongside GDPR, and if your users are spread across both, you are working under both. I am not your lawyer and will not pretend to be, but the practical consequences land in the architecture — where the database sits, what gets logged, how long records are kept — and those are decisions that are cheap on day one and expensive after launch.
The economy in London is evolving fast. Very fast.
Local businesses can no longer settle for a basic, aging website. Digital transformation is happening everywhere across England. 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 London 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 Kingdom 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 London want to order, book, or find information with a single tap, whether they are on their couch or commuting.
With Invent Better you get an installable build every two weeks, even when it is incomplete. That is the difference between following a project and waiting for one. You have access to the code repository from day one, and every decision is written down rather than remembered. A disagreement surfaces after two weeks, not at final delivery.
Software development is far too often treated as a terrifying black box.
In many traditional projects, you sign a massive specification document, you pay a hefty deposit, and then you just wait. For months, you receive nothing but vague updates. A few reassuring emails. A lot of "trust us, it is coming along great."
And then the day of the final big reveal in London arrives... and your heart sinks. The product looks and feels nothing like what you envisioned. But it is entirely too late, and your budget is completely gone.
The most important factor: when you work with me, that black box simply does not exist. Everything is entirely transparent.
You have made the decision to build your app for your audience in London. What happens next?
Many agencies will send you a fifty-page estimate, ask for a deposit, and then disappear for six months. That is the best way to crash straight into a wall.
Here is my step-by-step method for your business in England.
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?
If price is your only criterion, we are probably not a good fit, and saying so early saves us both time. A cheap build is rarely cheaper overall: code written without structure becomes impossible to change, so the second version costs more than the first would have. What you are really buying is the ability to keep changing the app after launch.
If price is your one and only criterion for choosing a developer in London, we are probably not a good fit to work together.
This is not arrogance. It is honesty.
Let's talk about the true value of things in our United Kingdom.
The healthcare sector leaves absolutely no room for error. Building a medical app for patients or doctors in England is not just about coding a pretty interface. It is about building a digital vault.
You have to seamlessly manage patient follow-ups, appointment bookings, medication reminders, and secure messaging. Strict compliance with data protection laws is non-negotiable. That is why we integrate heavy biometric authentication systems.
And let's not forget offline mode, which is absolutely vital for a rural doctor consulting in an area with poor signal.
If you are targeting travelers visiting London, your application must be their ultimate guide. And a guide that stops working the moment you cross a border is completely useless.
Offline mode is a matter of survival here to help your customers avoid roaming charges. They must be able to check a real-time itinerary or scan a QR code ticket even without an internet connection.
It is the question nobody asks a freelancer and the one worth asking first. My answer is three concrete things: the code sits in a repository in your name from day one, decisions are written down rather than kept in my head, and the store accounts are yours. Another developer can pick it up without me. That is not a promise, it is an arrangement — and you can check it in the first week.
You do, entirely, and from the start rather than at the end. The repository is opened in your name, you have access during development, and there is nothing to claim at delivery. The same goes for the designs and the store accounts. The only thing worth discussing is if you want to reuse a component I wrote elsewhere — I say so before using it, not after.
We fix it and resubmit, and that is part of the project. A rejection is not a rare accident: Apple checks dozens of points, and the common reasons are predictable — a test account that does not work, a permission requested with no explanation, an advertised feature that is not there yet. I deal with those before submitting, which guarantees nothing but avoids most of it. You never have to handle the exchange with the reviewer.
Yes, and you should know that before building on one. Apple and Google can remove an app that breaks their rules, and they change those rules regularly. Abrupt removals mostly hit apps that collect data without saying so, copy a brand, or have not been updated in a long time. It is also why a web presence stays useful alongside: nobody can take that one away from you.
It keeps running, and you keep everything needed to keep it alive: the code, the accesses, the signing keys, the documentation. I do a written handover rather than a file transfer — what was built, why, and where the traps are. It is half a day of work that saves whoever comes next several weeks of reverse engineering, and I would rather we parted that way.
Before any quote, there is a list to gather: the code repository, the App Store Connect and Google Play accounts — in your name, not the provider's — the Android signing key, and access to the hosting and database. The signing key is the critical piece: without it, the app can no longer be updated, it has to be republished under a new identifier, and you start again from zero installs.
Wherever you decide, and it is a decision to take early because it is expensive to undo. For most projects a European host is enough and keeps GDPR simple. For health data the hosting has to be certified, which narrows the choice and weighs on the budget — better learned on the first call than on launch day. In every case, the accounts are in your name.
I know before you see the review. A crash reporting tool sends the error with the device, the OS version and the exact place in the code — with no personal data. Without it, you discover bugs through store reviews, which is to say too late and in public. It is one of the few things I set up on every project, however small, because it costs almost nothing and changes everything.
On the code side, yes: every released version is tagged and we can return to the exact state of a delivery. On the store side it is more nuanced — Google lets you halt a rollout, Apple expects a fix to be published. The real protection is upstream: a staged rollout on Android, a real testing phase, and updates small enough that you know what broke.
It works, then it degrades slowly, and one day it stops launching. iOS ships a major version every September, Android every year, and each one breaks something. An app left alone for eighteen months usually costs more to bring back than the maintenance would have. You can stop — it is your call and I will not bill you a subscription for nothing — but decide it knowingly.
Ready to launch your app in London?
You have the idea. You know your market in England. 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.
30 minutes to start
Book →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.
