Antonin Karasek

senior developer of mobile apps for iOS and Android

Based in: Czech Republic Czechia Working area: global
Status: at your service Languages: English, Czech

I can develop your first-class iOS or Android app from scratch. The only thing you need to know about the development process is what problem the app should solve and for whom — and I’ll take care of the rest. Advanced apps also have a backend running on a server or in the cloud, and as a Java backend developer with 8+ years of experience, I can develop that one for you as well.

I have lots of experience with app-development projects of all sizes. Out of everything that I have successfully finished, my top reference from a technical point of view would be the iOS GearTracking app for tracking one’s sports gear. However, I have also developed complex e-commerce projects in a company I co-owned, and have worked as a developer and development manager for large companies. I know what companies expect from a senior freelance developer they hire. Therefore:

  • I only promise what I can and will deliver
  • I have advanced knowledge of the technology and understanding of backend architecture, having designed pretty complex systems as a software architect
  • I’m fluent in English, having worked for US and UK companies for eight years

Feel free to send me an email with a brief outline of your needs, and we can start our conversation from there. I will treat your inquiry as confidential and won’t waste your time with useless talk. Either I’m a good match for your assignment or not, and we can figure this out fast. As for pricing, I work with day rates and individually set job rates, based on my availability and on a quick assessment of your project and its specifics.


App Screens

GearTracking app — Activities screen GearTracking — Gear item detail

Here’s my idea of a perfect collaboration:

  1. Meet — A kick-off meeting or workshop 1-2 days long, where we define the target audience (3-5 personas), the key features and draft a few main screens.
  2. Design — I’ll create a wireframe of your app, which we will use to verify that users can complete the key use cases and that the main workflows can be followed intuitively.
  3. Develop — As soon as you approve the user interface design, the graphic designer will start to work on the final graphic designs, and I’ll start to code your app. We would check in every 2-4 weeks to review our progress and plan for what you may expect to see at the next meeting. As soon as it makes sense, you will have the development version installed on your device, and I would release updates as the development progresses.
  4. Release — When we are all satisfied with the final version of the app, I will help you to release it on the Apple App Store and/or Google Play. In general, I recommend keeping the first version as simple as possible (MVP), release it, and wait for the user feedback. It’s up to you if this will also be the final version or if we go through the cycle again and implement more features.
  5. Maintain — One thing to keep in mind is to review the app at least once a year when Apple or Google releases a new version of their operating system.

Firsthand recommendation

Not only have we pushed our iOS application a level higher (in-app purchases, menu UX improvements, verification flow), we also added another app for Slovakia — Hlídačky.sk. Tony took the development over perfectly. Our solution is not a standard one (a hybrid app which combines Swift and Turbolinks) but it enables us to move fast in a small team. Tony is precise and communicative. He knows the iOS platform by heart and we like working with him.
