Hi, Here My Short Information.

Designing With Passion While Exploring The World.

I specialize in building complex web applications, leading front-end teams, digital product design and developing visual design systems. I enjoy creating effortless user experience and designing delightful digital products. The entire process of going from a concept to release and gathering user’s feedback on either client’s or my own products is what makes me wake up everyday! Nowadays I lead product design at Tapdaq, previously I worked at Badoo and Socialbakers.

Earlier in 2016 I started turning my expertise into building my own digital design products. This helped me to learn even more about users and gain a deeper knowledge about launching and selling stuff as an individual. My best known products across the design community are currently Dashboard UI Kit 3.0 and Dashboard UI Kit totalling over 4000 sold copies.
