Is your mobile app or SaaS product losing users in onboarding, confusing them in core flows, or causing rework before launch? As a Mobile App Designer and UI UX Designer for startups, I turn those gaps into Mobile App Design and Mobile UI Design: UX flows, testable prototypes, and developer-ready Figma files. What I brought to a 0→1 mobile startup in 4+ years as Lead Product Designer and Mobile App Designer: • Shaped product direction with the founder: aligned UX/UI decisions with business goals, set feature priorities, and defined the core user flows for the pre-launch product • 50+ high-fidelity screens and a design system of 50+ components with variables and tokens, built faster with my own Claude AI workflow • A UX research system from scratch: 15+ user interviews, 31 user statements, and 5 proto-personas • A competitive audit of 37 platforms across 6 market segments for product positioning • TestFlight reviews to catch usability gaps before launch, plus the partner demo We start by finding your real problem: activation, navigation, a complex workflow, feature discoverability, or conversion. How I can help, depending on your product stage: • Mobile App Design for iOS & Android As a Mobile App Designer, I cover onboarding, core user journeys, navigation, edge states, and Mobile UI Design for iOS and Android apps. You get complete flows and interactive prototypes you can test before engineering invests in implementation. • 0→1 Product Design & MVP Design As your Mobile App Designer, I turn requirements, early ideas, or founder knowledge into user flows, information architecture, wireframes, prototypes, and final UI in Figma. You get a clear product scope before development starts, so your team validates decisions earlier and ships with less rework. • UX Audit & Mobile App Redesign As a Mobile App Designer, I review your flows, screens, user behavior, and friction points to find where users get confused or drop off. You get a UX audit, redesigned flows and screens, and prioritized recommendations for activation, conversion, usability, and retention. • SaaS Design & Dashboard Design As a SaaS Designer, I structure dense data, tables, filters, and multi-step workflows in web apps and dashboards. You get fewer unnecessary steps and a UI that scales as your product grows. • UX Research & Usability Testing As a Mobile App Designer, I turn user interviews, feedback, competitive analysis, and behavioral patterns into specific UX UI decisions. You get product decisions backed by real users, not assumptions. • Design Systems & Developer Handoff As a Mobile App Designer and Figma Designer, I build reusable components, variants, states, variables, and documentation. Your design and development teams get a shared system, consistent UX UI, and faster future work. AI-assisted UX, human-led decisions As a Mobile App Designer and Product Designer, I use AI tools and Figma Make to synthesize research, explore alternative flows, and get you to functional prototypes earlier. Product logic, UX decisions, and quality control stay human-led. A startup-ready Mobile App Designer Requirements change, priorities move, resources are limited. So the work fits what your product needs: validating the core flow before your team writes code, finding why your users drop off in onboarding, restructuring a complex SaaS workflow, or making your existing app clearer and easier to scale. You always get something concrete: user flows, wireframes, prototypes, Mobile App Design screens, design systems, or developer-ready Figma files.
