KlawsFX is the web development practice of Kyriakos Kaitezidis, a one-developer studio based in Xanthi, Greece. Despite the "FX" in the name it is not a visual-effects studio and not a Forex or trading brand: it builds websites, e-shops and web apps at a fixed price agreed in writing before the work starts.
Based in Xanthi, I take on remote projects across Greece. See also:
