About me
Intro
Senior Product Designer & Design Engineer with 14+ years of experience bridging complex UX, high-fidelity UI, and front-end implementation. I specialize in designing and scaling SaaS and AI-driven products from early stages to mature platforms. I’ve led end-to-end product design for large, complex B2B systems, partnering closely with engineering and leadership to simplify workflows, build scalable design systems, and ship high-impact features across web and mobile. What I bring to the table: - Design Engineering: I don’t just hand off static files. I prototype in code and collaborate deeply with engineering, contributing to React/TSX to ensure pixel-perfect execution. - Systems Thinking: I build scalable design systems that reduce engineering overhead and accelerate feature delivery. - Complex SaaS Expertise: I translate difficult B2B workflows (enterprise dashboards, fintech, proptech-like domains) into clean, consumer-grade experiences. - Outcome-Driven Design: I design for measurable business impact, improving usability, engagement, and retention across enterprise and high-traffic products. Tech stack: Figma, React, TypeScript (TSX), CSS/Tailwind, Rive, Lottie, Framer Motion.
