ABOUT ME
Swift developer and mentor, many years of experience, early adopter of all current state of the art technologies.
Swift developer and mentor, many years of experience, early adopter of all current state of the art technologies.

Available in all timezones. Excelent English.

I removed my old bio because it becomes outdated quickly. By now I've done enough to be able to say: I've really done a lot 🙂. I provide a full range of services to meet all your Swift needs.

Huge fan of functional programming, and can turn you into one too. I started with FRP frameworks all the way back in the Objective-C days. But its not just about Combine (which you should be using), FP is so much more. If by any chance you understand Czech, watch my old talk on functional reactive programming https://www.youtube.com/watch?v=MnEbZGv8t_c&t=1s

I know ObjectiveC well but I won't fix your ObjectiveC code, so what are we even doing here? 😀 Switch to Swift, then let me know.
