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.

Looking for a mobile developer in Dublin?

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 Dublin market or for the rest of your Ireland? 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.

They click. They quit. They forget.


What is a freelance mobile developer?

There is a massive difference between hiring a large agency and working with a freelance mobile developer in Dublin.

An agency is a heavy structure.

You talk to the sales rep. Who talks to the project manager. Who creates a ticket for the designer. Who sends mockups to the frontend developer. Who waits for the backend developer to finish.

Do you see the problem?

The loss of information is colossal.

And you are billed for every single step.

An experienced freelancer tears down all those walls.

In short: communication is direct and decisions are fast.

I know every single line of code in your project because I wrote it.

If you want to change a button, we do not need to hold a validation meeting with five different people.

This agility is crucial for technical quality.

Users have absolutely no patience.

Around 62% of users uninstall an app following a technical problem (Statista, 2025).

An unfixed bug means a permanently lost customer among the 1,173,179 people in Dublin.

By working directly with me, fixes are swift.

Updates are smooth.

You pay for expertise, not for someone's fancy office rent.

Mascot

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

I will tell you the truth, even when it's uncomfortable. That is the promise I make to all my clients from Bordeaux.

Creating an iOS or Android app takes time and money. So, no sugarcoating between us. With 12 years of experience under my belt, if your requirements are all over the place, I will pull the brakes.

The most important factor: I am here to make sure your investment actually serves your users. That is how we build great applications.

Why choose an expert in Dublin?

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.

Even if I am not physically sitting in your office in Dublin, you see absolutely everything that is happening.

To achieve this, we set up simple and highly effective workflows.

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.

End-to-end technical mastery

With Invent Better, the person who understands your project is the person who writes it. No sales representative, no account manager in between, no handover between three teams. You talk to the developer from the first call through to launch. On a first product, where most of the decisions are made in the first six weeks, that proximity is worth weeks of calendar time.

To make a great app, knowing just one programming language is not enough.

You have to understand the entire ecosystem.

I primarily work on native iOS projects (using Swift and SwiftUI) and Android (using Kotlin and Jetpack Compose).

The key advantage: a single developer masters the whole chain of your project in Dublin.

Android accounts for 72% of the global market share (Statista, 2025).

You simply cannot ignore it.

I also build cross-platform apps with Flutter when budget or timelines require moving faster on both systems simultaneously.

That is just the tip of the iceberg.

A mobile app is nothing without its backend.

It is like the kitchen of a restaurant.


My working methodology

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 Dublin.

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 Dublin.

Process mascot

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


From 50 pages to 5 screens: the art of simplifying

One day, a startup founder contacted me with a massive document.

He wanted the ultimate app to disrupt his entire sector in Dublin.

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 Ireland 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 Dublin that understand this are already ahead.

Mascot

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


You don't pay for hours. You pay for years of experience.

You are not buying typing time, you are buying twelve years of knowing what not to build. A wrong technical choice made in week one is invisible until month six, and by then it costs a rebuild rather than a conversation. Most of what you pay for is the decisions that never turn into problems.

When you hire me for your project in Dublin, 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 Leinster area will have of your business in Dublin.


Supporting Startups and SaaS

Tech companies need to move fast, but without breaking what already exists.

I perfectly understand the go-to-market pressure for startups in Dublin.

SaaS Platform Extensions

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.

Innovative Startups

Are you launching a new concept for the 1,173,179 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 Dublin that understand this are already ahead.


Tracking and post-launch support

What happens after the app goes live?

The work continues. An application is never frozen in time. With constant Android and iOS system updates, the code must be maintained. I offer maintenance packages to ensure your product always runs flawlessly for the 1,173,179 people in Dublin.

How do you handle the new Google Play rule?

Google now requires new developer accounts to test their application with 20 testers for two consecutive weeks before public release. I guide my clients to structure this testing phase and ensure the app meets Google's criteria without stalling the launch.

How are you notified of bugs?

The most important factor is being proactive. Do not rely on emails from your users: 96% of them never report a bug if they encounter one (2025). I always install crash detection tools in the background to be alerted instantly.

Can I get references from your past clients?

Absolutely. You can check my LinkedIn profile or my portfolio. I have loyal clients all over the world and in your Ireland who would be happy to speak with you about our collaboration.

Do you provide the database and backend?

Yes. As a full-stack developer, I configure all the invisible mechanics (Firebase databases or custom servers, security, APIs) so that your application communicates properly with your existing systems.

This is exactly what I offer to businesses in Dublin.

While you hesitate, your competitors in Dublin are moving forward.

The mobile world moves fast. Very fast. Today, 63% of global web traffic comes from mobile devices (Statista, 2025). If you keep pushing back the creation of your app, someone else will happily take your spot in Leinster.

But be careful, do not confuse speed with haste. Launching an unstable application is the worst possible strategy.

In short: you have to act fast, but above all, you have to do it right. ⏳

Working together remotely

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.
