Freelance and portfolio work as an independent product designer. Designed end-to-end product experiences for complex, data-driven platforms, reducing user-flow complexity by 20–30% through usability testing and iterative design. Built scalable UI systems with reusable components and structured user flows for products with complex information and workflows. Designed AI-assisted workflows including agent interactions and human-in-the-loop experiences. Conducted usability testing to identify friction points and improve task-completion clarity. Created interactive portfolio projects demonstrating product thinking and interface design decisions, and reduced design delivery timelines from three months to two through structured design work and faster iteration cycles.

Accelerated product design delivery timeline by 50% through rapid prototyping and short iteration cycles. Co-developed a design system to improve consistency and developer handoff efficiency. Iterated rapidly based on feedback and usability findings.
