What I'm looking for

I'm seeking product design roles where I can lead user-centered design, collaborate with cross-functional teams, use research-driven methods, and deliver measurable engagement and efficiency gains.

I am a dynamic Product Designer with over 7 years of experience building user-centric digital products. I leverage UX research, user interviews, and usability testing with Figma and the Adobe Suite to create responsive, intuitive interfaces that align with business goals.

My work has driven measurable impact — improving operational efficiency by 15%, reducing task execution time by 10%, increasing monthly active users by 22%, and delivering 30K sign-ups for a launched product. I collaborate closely with cross-functional teams and use iterative testing and journey mapping to continuously refine product experiences.
