A human-centered UI/UX & product designer with 4 years shaping B2B SaaS and AI-driven trade platforms. With a business degree behind me, I bring an analytical, product-minded edge — working end to end from research and information architecture to high-fidelity UI and design systems, and vibe-coding the front-end to bring designs to life. I measure what I ship, having moved core metrics 20–90% across products serving 10,000+ users.
