About Maria
There’s always a moment in a SaaS product where users think, “I don’t get this.” As a Senior UX Designer, I find and fix those friction points before they cost you users and revenue.
I partner with founders and product teams to provide Product Design expertise for existing builds. Whether you need a UX Audit to fix low engagement or a complete UI/UX Redesign, I perform a deep Heuristic Evaluation to translate complex user behaviors into clear, actionable improvements.
My approach combines UX Strategy, Behavioral Science, and UX Writing to identify exactly where users drop off in your User Flow.
Core Expertise & Recent Results:
Onboarding Optimization: Reduced drop-off by 50% for an AI marketing platform.
Product Audit: Uncovered 66 friction points in a language app prior to launch.
Dashboard Design: Simplified Data Visualization to reduce mid-session abandonment.
Conversion Rate Optimization: Aligning user needs with business goals for scalable growth.
Deliverables for your Development Team:
Redesigned Interaction Design patterns and Information Architecture.
High-fidelity Wireframing and key screens (Responsive Web).
Prioritized UX Research report with clear rationale.
Annotated Figma files for a seamless handoff.
