Hi, I’m Mark Pennieux. I’m a Product and UX Designer with experience shaping complex SaaS products in both early-stage and regulated environments. I focus on user research, discovery, and translating ambiguous requirements into clear, usable solutions. I’ve worked end-to-end across the product lifecycle, collaborating closely with product, engineering, and QA to deliver practical, user-focused outcomes in high-stakes systems. I thrive on turning business rules and policies into intuitive workflows, scalable UX patterns, and measurable improvements in visibility, ownership, and efficiency. I enjoy validating ideas with real users, communicating clearly with stakeholders, and delivering designs that balance user needs with regulatory and accessibility requirements.
