I have a passion for user interface design and user experience, believe in creating the best possible experience on whatever device. Several years’ experience working in various industry sectors, on different technology stacks while working in small and large teams.

Hands-on experience designing, UI prototyping and back-end integration in a product’s life cycle. I embrace latest tools and technologies and as a Certified Scrum Master I strongly believe in agile development.

Currently my interests lie in creating consistent user interfaces through the use of design systems.
