Everyday I crush code, generate new ideas, enjoy opportunities for creativity, develop useful apps, write articles and share it with the world, drink 2 liters of water and a bucket of green tea.
My name is Denis Kazakov and I am a software engineer and a freelancer. Now I am focused on mobile apps development and backend for them. In general, I can develop any software for devices that can launch .NET framework. From watch and iron to space station and Large Hadron Collider.
Along with IT activities, I like to watch and play football. In my youth I was a professional footballer and captain of a major league team. I read a lot and like non-fiction books and biographies. I inspiring by visiting new countries and places. Restore my intellectual power in gym and with my lovely massagist. And of course I like to spend my free time with my 2 daughters, wife and scottish cat.

Denis is a rockstar when it comes to development. He is truly a delight to work with and he brings indescribable value to the projects he works on. I enjoyed the first project that I worked on with him and we just started our second. There is no doubt I will continue to hire Denis for all of my development needs. Plus, he is extremely organized. I truly appreciated all of the reports I would receive from Denis with every release.
Denis is a true expert, anything you want doing - he can make it happen! He is very organised, provides clear communication, fitted very well into our team, and not only created the app we asked for, but advised on key improvements which has led to an app which has surpassed expectations. A big thank you Denis, we look forward to working with you again!
Denis has deep experience in many technologies and has delivered high quality work. Its was a pleasure to work with Denis, not only does he have a very pleasant and professional work ethic, he is able to guide and advise on risks of implementation methodologies. Thank you Denis, see you again!
Denis made significant contributions to our software and we wish him all the best in his future endeavours
Again, there's no other way to say it, Denis is an incredible developer who has a growth mindset and can deliver incredible results.
