SERVICES
My Focus
Having been in software 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.
Mobile App
20+ apps developed
I truly understand mobile development. I began programming for iOS with version 4. Do you even remember what it looked like? I certainly do!
eCommerce
10+ eshops released
OpenCart, PrestaShop, WooCommerce, Shopify, Magento. Some we may dislike, some we accept, and some I absolutely love to work with.
Web Development
30+ web pages created
Most frequently, I build web pages on WordPress. However, sometimes a CMS is not sufficient, and I aim for a more robust and high-performance framework.
FinTech
Yes, I have extensive experience in FinTech. I have collaborated on a widely used banking solution across different countries in Europe.
Capital Markets
My experience in capital markets comes from my own products that focus on US Equities. Charting, dashboards, machine learning.
API Integration
Whether it’s connecting a payment gateway to your system or integrating with an internal database, I’m here to assist you.
From hybrid app 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!
Could You Fix It?
“I heard you studied Information Technology. Could you repair my broken iPhone?”
I’m sure some of us know how to fix it, but we are software developers. We can make a beautiful website for you, a handy mobile app, or maybe a desktop application.
Code Monkey
Yes, I’m a software engineer, but that doesn’t mean I find enjoyment solely in sitting in front of our computers for 8 hours.
I love to see Lando taking podiums in Formula 1 or Anthony Joshua knocking out his opponents, but when it comes to knockouts, I’d prefer to see Jake Paul being on the receiving end.
3 W – Who I Work With
Most of my clients are smaller businesses that don’t have an internal software development team. They excel in their business, and we excel in technology. Together, we combine our knowledge to mutually grow and succeed.
I frequently aid larger businesses in establishing a new development department. For instance, if you already have a team of web developers and require an urgent mobile app development, I’m ready to start immediately. Later, when your internal team is prepared, I can hand over the product to them.
I Love Stock Markets!
Over the past few years, I’ve been working on several applications supporting traders.
It started as a regular job but ended as a passion. I developed a complex platform that clusters several data endpoints, providing analytical tools for developing a strategy.
I delved deep into the order book using low-level APIs and implemented a custom browser enabling machine learning to inform traders about spoofing, iceberg orders, hidden sellers, or buyers.
I take pleasure in crafting stunning websites, but if you’re a trading desk in need of tech support, I’m fully dedicated to assisting you.
Smart Development for STARTUPs
If you’re a startup looking to scale smartly, you’ve come to the right place.
I’m a software developer passionate about helping startups grow by providing top-notch development support without the high overhead of an in-house team. From mobile to web development, I can tackle essential parts of your project, saving you time and money while delivering quality that helps you hit the ground running.
Let’s team up to bring your vision to life, maximize your budget, and accelerate your path to success!

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 States: 8 – 6 p.m. (EST)
Over the past seven years, I have perfected our client collaboration model, enabling seamless work with clients from Europe, and the USA.
I understand the challenges of different time zones and have implemented effective communication and project management strategies to overcome them.
