Senior UX/UI Designer | SaaS, Dashboards & Design Systems, AI-assisted

I help B2B SaaS and enterprise teams simplify complex workflows, design new product features, and turn business requirements into clear, development-ready UX/UI. You do not need to prepare perfect wireframes or describe every screen before we start. Share the product goal, business requirements, existing product context, and known constraints. I will work through the UX logic, user flow, states, interface, and developer handoff. I can work with your current product managers, developers, founders, and internal designers. I learn how your team works and become an extra senior product design resource where you need one. WHAT I CAN HELP WITH • New SaaS features and product modules • Complex workflows and user journeys • Data-heavy dashboards • ERP, CRM, admin panels, and internal tools • UX/UI redesigns • Design systems and Figma libraries • Interactive prototypes • Responsive web applications • Marketing websites for complex tech products I can take an existing requirement, work through the UX, cover the edge cases, create the final interface, and prepare everything for development. Why clients choose me • I can work independently without constant design management • I understand complex B2B, SaaS, ERP, and enterprise products • I work directly with product managers and developers • I focus on product logic before visual decoration • I design complete features, not disconnected screens • I consider how every new feature affects existing flows and components • I stay involved when developers have questions during implementation Industries I’ve worked with: 🏭 Manufacturing & Machinery | 🚛 Logistics & Warehousing | 📦 Supply Chain & Inventory | 🛒 Procurement & Purchasing | 💰 Finance & Accounting | 📊 Reporting & Analytics | 🏢 Real Estate & Portfolio Platforms | 🍽️ Food & Beverage | 🛡️ Cybersecurity | 🖥️ Internal Enterprise Systems 🛠 How I use AI I use AI to organize product context, explore different flows, identify possible edge cases, improve UX copy, and prepare documentation faster. The final product decisions still come from me. I review the logic, constraints, trade-offs, and impact on the existing product before anything is delivered. 🛠 Tools Figma (main) | FigJam | Sketch | Adobe XD | Photoshop | Illustrator | After Effects | Principle | Axure RP | InVision | ClaudeCode 📌 Keywords: UI UX Designer • UX UI Designer • SaaS UI UX • B2B SaaS UX/UI • Enterprise UX Designer • Figma UI UX • Figma SaaS Designer • Figma Expert • Product Designer SaaS • Web App UX UI • Dashboard UX UI • Admin Panel UX/UI • Internal Tools Design • Enterprise Software UI UX • Complex UX Flows • User Flow Designer • UX Architecture • UX Strategy • UX Audit • UX Research • UX Wireframes • UX Optimization • Conversion-focused UX • User Journey Mapping • Customer Journey Map • Task Flow Optimization • Data-heavy UX • Process-heavy UX • Workflow UX • Information Architecture UX • UI Component Library • Design System Expert • Design Tokens • Auto-layout Figma • Prototype Design • Interaction UX • User Testing UX • Heuristic Analysis • UI Redesign • UI UX Designer • UX UI Designer • SaaS UI UX • B2B SaaS UX/UI • Enterprise UX Designer • Figma UI UX • Figma SaaS Designer • Figma Expert • Product Designer SaaS • Web App UX UI • Dashboard UX UI • Admin Panel UX/UI • Internal Tools Design • Enterprise Software UI UX • Complex UX Flows • User Flow Designer • UX Architecture • UX Strategy • UX Audit • UX Research • UX Wireframes • UX Optimization • Conversion-focused UX • User Journey Mapping • Customer Journey Map • Task Flow Optimization • Data-heavy UX • Process-heavy UX • Workflow UX • Information Architecture UX • UI Component Library • Design System Expert • Design Tokens • Auto-layout Figma • Prototype Design • Interaction UX • User Testing UX • Heuristic Analysis • UI Redesign • Workflow Automation UI • Operational Tools UX • Team Productivity Tools UX • Internal Admin Tools UX High-Fidelity Prototypes • Interactive Prototyping • UI Mockups • Wireframe to UI • Low-Fidelity UX User-centric UX • Task-based UX • Problem-solving UX Web Application Designer • System UI Designer • Data Visualization UI UI/UX Consultant • UX Problem Solver • Product Design Consultant Login/Signup UX • Onboarding UX • Multi-step Processes UX • Form UX Design
