I had the pleasure of working with Krisz on the WeShop MVP. During the course of the 6 months, I spent on the project Krisz showed not just brilliant skills in design and UX but also excelled himself as wearing the product manager hat during the time when the position was unfilled.
He channelled flux of feature requests and design iterations through his department while making sure that the developers have been briefed with clear mockups, prototypes and design. He always had bright ideas to improve the application and was keen to take the extra mile necessary to achieve those enhancements. I hope to have a chance to work with him in the future.
