Placard
This project is a conceptual mobile application for a local "coffee & go" cafe format that specializes in quick service, seasonal menu, and cozy urban style. The main idea is to create a convenient interface that allows ordering drinks and snacks in advance, avoid queues, and improve interaction between the establishment and its regular customers.

Stage 2: Refinement of the website UX/UI designer
If you are in doubt about choosing a designer for your product - I definitely recommend Konstantin. He is a person who truly understands design and is passionate about his work. I ordered the illustration of a few details, but Konstantin, on his own initiative, proposed much more effective solutions and completed significantly more work than was planned. The task took a little more time, but the result is absolutely worth it. Thank you sincerely for such an approach!
