Have you seen his logos? I was dazzled by his capacity to create spot-on logos within a short deadline. Moreover, Martin protects his creative ideas to the right extend, placing the customers' needs as a common goal and working towards the best outcome. This results in splendid UI solutions in several of the Bulpros' products that we are working on. I am always grateful to discuss a UX side of a given project with him, as I know he will bring both knowledge and vigor to it. You should also check his in-depth 3DS-max tutorials on YouTube, which prove his commitment to a zealous career in the design field.

The level of detail and professionalism that Martin invested in the project was clearly visible. The quality work he does for NEXT TV is key in the success of the project.
