About

I’m a frontend developer with a Bachelor’s degree in Graphic Design and over 14 years of experience building user-focused digital products. My background in design helps me bridge the gap between aesthetics and functionality, so I naturally think about both how things look and how they work.

Over the years, I’ve worked across a variety of industries - from advertising and startups to education, corporate ICT, and government SaaS - which has taught me how to adapt quickly and bring value in different environments. I also have experience as a Scrum Master and hold a PSM I certification, giving me a strong foundation in agile ways of working and helping teams collaborate effectively and deliver meaningful results.

I enjoy solving complex problems, improving user experiences, and working closely with others to turn ideas into well-crafted products.
