👋 I'm a full-stack UX designer with 5+ years of experience in fintech, AI, and enterprise tools. I specialize in end-to-end product design—from 0→1 launches to scaling complex systems.
👧🏻 I bring soul to systems. My goal is to solve hard problems without making them feel hard to use.
Highlights of my work:

🛡️ At Binance, redesigned a fraud detection tool that tripled analyst efficiency
🤖 At Microsoft, reimagined a Copilot plugin to boost team collaboration and productivity
🚀 As the founding designer at a healthcare startup, launched the app and helped raise $600K
💼 At Jobscan, simplified an AI resume tool, increasing engagement by 41%

I thrive in cross-functional teams, collaborating closely with PMs and engineers to build impactful and intuitive products.
