In short: for your Dublin (1,173,179 residents) project in Leinster, you work directly with me, not a middleman. 12 years of experience, 15+ apps delivered, and a transparent end-to-end process.

Google Play hosts over 2 million apps.

How is yours going to stand out in Dublin?

It will not be with average design or constant bugs.

Users are ruthless.

A slow app means an immediate uninstall.

The key advantage of an expert developer is complete mastery of this chaotic environment.

Android means thousands of different screen sizes. Processors that vary wildly.

Building an Android app development project in Dublin requires extreme rigor.

You have to know Google's rules. Battery constraints. Ever-stricter permissions.

I handle all of that for you.

My goal is for your app to become obvious and essential for your customers in the Leinster area.

Not just another digital paperweight.

We set a real strategy. We build it cleanly. We launch it successfully.


What is Android development?

People often ask me whether to start with iOS or Android for a project in Dublin.

The answer depends on your target audience and your budget.

The key advantage of Android is its massive reach.

Especially in emerging markets or for the general public.

But there is a fundamental difference with Apple.

Apple controls everything. They have about twenty iPhone models in circulation. It is easy to test.

Android is the wild west.

Google reports there are more than 24,000 active Android device models.

Some have tiny screens. Others run on Android versions that are five years old.

This fragmentation makes testing much more complex and expensive.

You have to ensure the app does not crash on a cheap four-year-old phone, while still leveraging the power of the latest Samsung Galaxy.

However, Android is often the best choice to start if you are doing B2B in the Leinster area.

For example, equipping your delivery drivers or field technicians with inexpensive rugged tablets.

In that scenario, Android's open ecosystem is unbeatable.

The key point: the price depends on the technical complexity under the hood, not on the number of pages.

Mobile Product Engineer — Cannes, France

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.

Why choose an expert in Dublin?

The economy in Dublin is evolving fast. Very fast.

Local businesses can no longer settle for a basic, aging website. Digital transformation is happening everywhere across Leinster. 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 Dublin 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 Ireland 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 Dublin want to order, book, or find information with a single tap, whether they are on their couch or commuting.

Working with Dublin

Dublin is an hour behind me and full of companies whose head office is somewhere else, which usually means the app has to fit rules written in another country. Worth naming early: the constraint is rarely technical, it is which jurisdiction's data rules the product has to satisfy.

That question has a habit of arriving late and changing a lot. An app built for Irish users, then extended to a US parent company's customers, may suddenly need different consent flows, different retention rules and a different hosting region. None of those are difficult in themselves. All of them are painful once you have live users, because changing where data lives means migrating it, and changing what you collect means deciding what to do with what you already collected.

Dublin's concentration of large technology employers has a second effect worth being straight about: the local market for developers is competitive and expensive, and a lot of the enquiries I get are from people who have already tried to hire and found the timeline unacceptable. That is a legitimate reason to work with someone outside, and it also sets a fair expectation. I am one person. I can carry a product end to end and I can do it quickly, but I cannot replace a team, and if your project genuinely needs one I will tell you at the start.

The practical side is easy. One hour of difference means our working days are effectively the same, so questions get answered within the hour rather than the day, and a weekly call is enough structure for most builds. English is the working language throughout, which removes the small friction that translation adds even when everyone involved is competent in the other language.

Why Invent Better?

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 Dublin 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.


How does an Android project work?

The worst mistake is coding for 6 months without ever testing anything in real conditions. Here is how we work together to launch your app in Dublin. First, we define the scope. We cut everything that is useless. We keep the essential. Then, I develop. I deliver test versions to your phone regularly. But the crucial step on Android is publishing on the Google Play Store. It is no longer a magic button. Google now requires 20 different testers to use your app for 14 consecutive days before you can make it public. The most important factor is anticipating this delay. During this phase, we fill out the data safety form. We prove to Google that your app respects privacy. Once approved, we do not launch it to a large all at once. We do what is called a "Staged Rollout". We deploy it to most users in the Leinster area. We monitor for crashes. If all is well, we move to a large share, then a large share, then a large share. It is the only professional way to launch an app without risking a disaster on launch day.

A transparent, iterative process with zero surprises. You see the app grow every single week.


Android Case Study

Let's take a concrete example.

A client contacted me to build a home services booking app, specifically targeting the Leinster 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 Dublin 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.

Mascot

In short: we do not build everything. We build what your users actually need.


How much does an Android app cost?

Treat an Android budget as a growth line rather than an expense, because that is how it behaves. Someone online will code something for almost nothing, and it will be slow, insecure and impossible to extend. The useful comparison is not one quote against another, but the cost of building it twice against building it once.

When talking budget for an Android app in Dublin, you have to change your perspective.

It is not an expense. It is a growth tool.

You can find someone on the internet who will code you something for almost nothing.

Spoiler: it will be a technical disaster. Termites in a house.

The app will be slow on half of your Ireland customers' phones. Bugs will pile up. You will lose credibility.

In short, redoing a poorly coded app always costs more than doing it right the first time.

With me, you are not buying lines of code. You are buying a solution.


Android Industries

I do not have a reserved domain. I adapt to your market in Dublin.

The key advantage of Android is its technical flexibility.

Retail & E-commerce

If you sell products, the purchase must be seamless. Android phones dominate the market. Ignoring this platform means cutting yourself off from the majority of your customers in the Leinster area. We use the NFC reader to scan loyalty cards or Google Pay for one-click payments. The goal is to eliminate all friction at checkout.

Transport & Logistics

This is where Android truly shines. Delivery tracking, apps for drivers in Dublin. You can use fleets of inexpensive Android terminals. We leverage background geolocation, essential for real-time tracking. Drivers do not have time to click fifteen buttons; the interface must be huge and obvious.

Tourism & Events

Thousands of people gather. Cellular networks saturate. The festival or tour guide app must work a large offline. On Android, we use robust local databases so the map and schedules are always accessible. It is a question of user logic.

Frequently asked questions

What happens if you are unavailable mid-project?

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.

Who owns the code once the project ships?

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.

What happens if Apple rejects the app?

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.

Can my app disappear from a store overnight?

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.

What becomes of my app if we stop working together?

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.

How do I take an app back from another provider?

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.

Where is my users' data hosted?

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.

What happens when the app crashes on a user's phone?

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.

Can we roll back if an update goes wrong?

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.

Does the app keep working if I stop paying for maintenance?

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 Dublin?

You have the idea. You know your market in Leinster. 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.
