Founder at PlanArty

I’m an entrepreneur with a BS degree in Computer Science. I also enjoyed attending a One Day MBA with Brian Tracy and several business seminars with Lorand Soares Szasz.

My passion for time management started in the early days of my company, when I realized that there is one thing in this world that you cannot get more of: time!

As a result, I started reading everything I could get my hands on about time management, time planning, prioritizing, procrastinating, and time tracking. Armed with this information, and together with my great colleagues, I have created our best friend: the PlanArty time management system.

I hope you will find helpful information in our blog articles and on our site in general.

Should you have any questions, suggestions, or ideas for improving our effectiveness, please don’t hesitate to contact me at

Happy reading and planning!
