About me

My career spans B2B SaaS platforms, enterprise workflows, and design systems across banking, logistics, healthcare, and e-commerce. I've led end-to-end UX/UI for large-scale, multi-device projects, from physical service devices to web-based admin systems, and I've spent the past year integrating AI tools like Claude and Claude Code into my design and front-end workflow.

I've enjoyed creating things since I was young, from drawing on MS Paint as a kid to designing club posters in Photoshop. That curiosity led me to study Communication Design, and it's shaped how I approach every project since.

I'm especially drawn to projects with real complexity — systems with many moving parts, accessibility constraints, or fragmented workflows that need structure. Outside of work, I'm an outgoing person who enjoys walking, sports, and hunting down new coffee spots around the city. I'm also a big fan of dogs and cats.
