This is an excellent landing page. It has a clear call to action and a simple way to capture leads. You may want to change this text "Hi, I'm Aziz Berkay Yesilyurt. I transform tedious workflows into streamlined software." to be details on your call to action ("Automate Your Workflow with One Call".) This landing page is not going to win you any business on its own. Its further down your funnel. Whether you are running ads or writing content or just word of mouth telling folks about this site after you meet them, your clients will be learning about you from outside of this site. I would think of it as your business card.
