All my professional life I have been doing my best to write great software and provide on-time delivery for my customers. I worked in different teams, for various industries, with different stacks and methodologies, but in all cases, the only thing permanent is client-centric oriented service. It is important. We all know that service it is our actions that create value for others. Sounds like caring, right? Yes, it does. This is a kind of care but in the world of IT business, we used to describe it in words such as collaboration, delivery, budget, etc. "The definition of genius is taking the complex and making it simple." ― Albert Einstein, and I am following it.In recent years, my experience is all-around Search Engine development.
