References

František has been working with me for over a year on several of my apps, including Itemlist and QRGenie. He is detail-oriented, communicates clearly, and consistently delivers high-quality code. František can take on complex tasks and new features with minimal input, handling everything from design details to code architecture with great skill. It’s been a real pleasure having him on board.

I had a great experience working with this iOS developer. The app was developed smoothly, communication was clear, and everything worked as agreed. Post-launch updates were handled promptly, and all adjustments and feedback were implemented quickly and professionally. I can definitely recommend this developer and would be happy to work together again.

Have an app in mind?

New apps, features for an existing one, or a second pair of eyes on your Swift code.
