Fantastic - love this guys work. No matter how complicated it gets, he can do it!

Great, fast work. Extremely easy to work with!

Had some complex tasks I was getting stuck with. I was apprehensive that there were no reviews at the time, but thought I'd give him a go. I had absolutely no need for concern, he easily understood the task, completed it expeditiously, suggesting improvements to existing and redundant code. Reliable, fast, helpful, great communication and hugely knowledgeable. I will most definitely use again, although with this talent, I expect he'll be working for some big cooperation on big money very soon!

Once again excellent work delivered on time, Karel exceeded my expectations and surpassed what was asked of him!!

Karel was completely excellent!!! I have never worked with a better freelancer on this platform.
He went above and beyond anything that was asked, understood the requirements first time and delivered the project perfectly on time. If you are reading this you absolutely have to hire him for your task and I guarantee you will be very pleased with what is delivered.
