About

Professional summary

I am a Senior Product Designer with more than seven years of experience designing and evolving digital products across e-commerce, fintech, education, healthcare, and SaaS.

I specialize in product discovery, UX/UI design, interaction design, user flows, wireframing, prototyping, usability testing, and Design Systems. I connect user needs with business goals and technical requirements to create practical, user-centered solutions.

I have experience conducting UX research, user interviews, benchmarking, research synthesis, and usability testing. I use these insights to define problems, validate hypotheses, and improve end-to-end digital experiences.

I work closely with multidisciplinary teams, stakeholders, developers, content teams, media teams, and data professionals throughout the product lifecycle. My work spans discovery, prioritization, planning, implementation, validation, and continuous improvement.

In addition to product design, I bring experience in project coordination, backlog management, agile ceremonies, resource allocation, and delivery management. I am comfortable facilitating alignment sessions and helping teams move initiatives from strategy through execution.

My background also includes visual design, branding, packaging, digital marketing materials, video, animation, and team management. This broad design foundation helps me balance usability, visual consistency, and business impact.
