Everything starts with an idea. Now it’s time to explore the possibilities, limitations, constraints, shortcuts, and cost. During this phase, we seek answers to all these questions.
Start working!
In the previous stage, we gathered all the necessary answers, and now it’s time to deliver. We keep you informed and strive to involve you as much as possible to avoid any surprises.
ABOUT ME
I’m a detail oriented mobile app developer!
If you are searching for a large software company, you are in the wrong place. Instead, you’ve found a skilled software engineer with extensive experience in mobile development, ready to support your digital journey.

SERVICES
My Focus
Having been in mobile development for almost a decade, I’ve tackled a variety of engineering tasks. Here are some of the most common ones, but not an exhaustive list. Book a free consultation with me to find out if I can assist you.
iPhone App
20+ iPhone apps developed
Most of my clients require native iPhone apps. Having successfully delivered over 20 iPhone apps to the market, I have gained extensive knowledge and hands-on experience in creating high-quality, user-focused applications.
iPad App
5+ iPad apps released
With the latest Apple SDKs, developing iPad applications has become more streamlined and efficient, reducing both complexity and development time.
macOS App
5+ macOS Desktop app created
While users love their iPhones, there are certain tasks where a desktop app is the preferred choice. Whether you choose to focus on mobile, desktop, or both, I’m here to handle the development for you.
Rewriting hybrid apps to native
Is your app built in Flutter or React Native, and you’re considering going native for iOS and Android? I’m here to help!


This is exactly the kind of project I enjoy most! Why? The application is already released, so there’s no guesswork about how it should look, and the scope of work is clear from the start. The APIs are live, and screens are defined. We can begin almost immediately. Plus, there’s an added bonus: when rewriting, there’s always room for improvements, making the next version even better!
Technology Stack
I focus on the latest Apple development stack, cutting-edge technologies, and modern architecture principles such as composition, separation of concerns, and more.

Swift
Programming Language
Transitioning from Objective-C to Swift marked a significant milestone in Apple development, revolutionizing how apps are built. Today, every application I develop leverages the latest version of the Swift programming language, ensuring modern, efficient, and robust solutions.

SwiftUI
User Interface Library
SwiftUI is a relatively new technology shifting from an imperative to a declarative approach. While it still has some limitations, it can significantly accelerate development. For areas requiring tried-and-tested solutions I use UIKit seamlessly integrated alongside SwiftUI.

SPM
Swift Package Manager
A cornerstone of modern Swift-based development to structure independent code components. This approach enhances code reusability and scalability, making software easier to maintain and expand. Instead of reinventing the wheel, I focus on reusing proven solutions.
ABOUT ME
Developing Since iOS 5













My journey in iOS development began back in 2011, working with iOS 5. Since then, the platform has evolved significantly, and I’ve grown alongside it.
Over the years, I’ve gained extensive experience in mobile development, ensuring I have the skills and expertise to confidently bring your ideas to life.
Start Up Experience

Transforming an idea into a working product takes time—and a lot of Coca-Cola. Countless hours were spent, and even more lines of code were written.
From proof of concept to alpha and beta versions, from coding to strategizing about product and marketing, it was a tough period in my life. But I learned lessons that I would never have gained in a traditional job.
Teaching Junior Developers

During my career, I’ve had the privilege of working with many great people and talented software engineers. Thanks to them, I’ve grown into a strong software developer. I write clean code, understand how to think about products, and follow key architectural principles to build high-quality software.
Keeping all of that to myself would be selfish, which is why you’ll often find me at conferences and events, sharing my experience with younger software engineers.
Staying Active!

Yes, I’m a software engineer, but that doesn’t mean I find enjoyment solely in sitting in front of my computer for 8 hours.
I’m keen on playing football, go-karting, boxing, or even snowboarding.
FinTech Experience

I’ve spent a significant portion of my career as an iOS developer for one of the largest banking groups in Europe. I started as one of three developers and, by the time I left, the team had grown to 20 iOS engineers.
During this time, I experienced several transformations. One major change was the team structure. Another was rewriting the entire application from Objective-C to Swift, a complex process that required extensive work, focus, and well-defined procedural steps.
Self Started Attitude

When working on a project, I don’t just blindly follow requirements. I always think outside the box to maximize business value while ensuring a great user experience.
With work comes new ideas, and you can expect me to be proactive in suggesting more elegant solutions to problems or proposing features that could add more value to your business or app. Simply put, I’m not a passive software engineer.
Not Only Mobile Apps

Yes, most of my projects have been mobile apps, but that’s not my only experience. Over the years, I’ve developed several modules for different purposes. Some were designed to build functionality for platforms like WordPress, Drupal, and even PrestaShop or OpenCart.
I’ve had the opportunity to integrate payment gateways into e-commerce sites, create several web pages, and work on a custom ERP system for a local client.
Additionally, I built a robust backend system using Ruby and Python which dynamically generated documents, saving a significant amount of time. And that’s just a fraction of my software engineering experience.
I also conduct code auditions for architectural reviews. This involves evaluating code quality, design patterns, and overall system architecture to ensure that best practices are followed. I collaborate with teams to identify areas for improvement, optimize performance, and ensure scalability.

Frequently Asked Questions
How much does it cost?
The most challenging question in software development. I believe that transparency is a key, and, therefore, I charge you at an agreed hourly rate, depending on the complexity of your desired project.
Before I start with development, I provide a rough estimate of the total number of hours required to deploy your product. You pay as we progress, and at any point in the process, you have the freedom to terminate the work or make significant changes to the project’s direction.
Do you work with a clients in different time zones?
I have experience working with clients in various time zones.
🇪🇺 Europe: 8 – 5 p.m. (CET)
🇬🇧 United Kingdom: 9 – 6 (GMT)
🇺🇸 United States: 8 – 6 p.m. (EST)
Over the past seven years, I have perfected our client collaboration model, enabling seamless work with clients from United Kingdom, Europe, and the USA.
I understand the challenges of different time zones and have implemented effective communication and project management strategies to overcome them.
