About

For over 10 years, I’ve been building digital products across startups, enterprise environments, and emerging technology sectors. My work sits at the intersection of engineering, UX and product thinking, with a strong focus on creating intuitive experiences that connect technology with human behavior.

Outside of work, I’m inspired by travel, cultural exploration and artistic expression. I enjoy learning languages, attending meetups and conferences, reading and participating in book clubs, journaling, music, woodworking, and interior design.
