My most experienced specialization is full cycle of books & magazines design, layout and prepress. For my 20+ years career, I made lots of magazines. Some of them — from scratch, in other cases I joined existing teams. Yet not only magazines, but everything that could be printed. I made brochures, calendars, booklets, leaflets, posters, etc. in the number of plenty. Also I designed packages for various products. And many species of clothing prints. A couple years I worked as prepress engineer in printing house, that made my understanding of printing processes much deeper. Another specialization of mine is photo editing and retouching. It started as part of print production and ended up (well, not yet ended) with me as Photoshop teacher at photo school. I have been fortunate to work with very meticulous photographers on very complex projects. Sometimes as part of photo manipulations and sometimes as part of digital illustration, I have some experience in 3D graphic and AI generated visuals. As world become more digital, my curiosity leaded me to another side of graphic design, where printing is not that important. So, motion design, web design and UI/UX was added to my competencies. Competencies: Photoshop, InDesign, Illustrator, digital illustration, layout, print, prepress, logo design. Curiosities: After Effects, Cinema 4D. weniger
