🥇VERIFIED TOP 1% Designer on the Upwork. 🧑‍💻 10+ years of experience in UX/UI design for SaaS Web Applications. 💼 Clients: Toyota, DJI, Tesla, Johnson & Johnson, Helly Hansen, Siemens, Nikon, Inditex. My typical design process and methods: 1️⃣ Project Onboarding & Cost Estimation I review all project materials and documentation, dive into your product and goals, and identify key challenges. Based on this, I create a clear step-by-step project plan with phases, timelines, and dependencies, and provide a transparent estimation of hours and total cost. You receive a structured roadmap showing what we start with, what follows next, how the project is broken down by stages, how long each stage takes, and when each phase will be delivered. ⚡️ Sitemap & Functional Requirements (Optional) If user scenarios (User Stories) are provided, I create a structured sitemap outlining all modules and their main functions. This visual map clearly shows how sections relate to each other, the flow between screens, and the key requirements for each module, providing a solid foundation for both design and development. 2️⃣ Research and UX & Usability Audit ⚡️ UX & Usability Audit I review the existing application to identify friction points, unclear user flows, and areas where users may get stuck. All findings are delivered with annotated screenshots highlighting issues and recommendations. ⚡️ User Behavior Analysis Using Hotjar, Google Analytics, and other tools, I analyze real user interactions through session recordings, heatmaps, and collected user feedback to validate assumptions, identify pain points, and uncover opportunities for improvement. ⚡Competitor Analysis I analyze competitors to identify strengths, weaknesses, and opportunities, uncovering gaps and potential areas for improvement. This helps optimize product features, discover effective UX patterns, avoid design mistakes, and implement proven solutions that enhance usability and overall user experience. 3️⃣ UX Part. Low-Fidelity Wireframing I create low-fidelity wireframes for each screen and user flow to validate functionality, logic, and overall structure before visual(UI) design begins. These wireframes define content placement, interaction patterns, and layout based on user needs and business goals. 4️⃣ UI Component Libraries & Style Guides I define the design system for your product, choosing from popular frameworks such as Material UI (MUI), Tailwind UI, Ant Design (AntD), React Bootstrap or Element UI, based on project requirements and scalability. This includes creating a comprehensive style guide that documents typography, colors, spacing, and how each component functions, enabling developers to maintain consistency and simplicity in future design and development. For large-scale products, I develop an enterprise UI kit, including reusable components like complex tables, charts, and forms, ensuring consistency, efficiency, and scalability across the entire product. 5️⃣ UI Design I create the high-fidelity visual design of the product, including typography, color palette, imagery, and iconography. Designs are based on the approved wireframes and reflect the brand identity, ensuring a unique, visually appealing, and user-focused interface that engages the target audience. All screens are delivered ready for development, with consistent layout, style, and interaction details. 6️⃣ Prototyping – Clickable Figma Prototypes Once high-fidelity UI designs are ready, I create clickable prototypes in Figma, linking all screens and user flows. These interactive prototypes simulate the real product experience, allowing stakeholders and users to navigate through the app, test functionality, and validate the design before development begins. 7️⃣ Usability Testing – Prototype Validation I conduct usability tests on the interactive prototypes to evaluate the ease of use, clarity of user flows, and overall experience. This allows us to identify and fix potential usability issues before development starts, ensuring the product is intuitive, efficient, and aligned with user needs. 8️⃣ Development Support & Handoff I prepare all Figma designs for development with detailed specifications, including component states (Error, Empty, Loading) and all necessary assets. This ensures a smooth handoff, allowing developers to implement the design accurately and efficiently, while maintaining consistency and quality across the product. 9️⃣ Project Support & Design Supervision After the design is completed, I continue to support the project by supervising the implementation and ensuring design quality throughout the development cycle. This includes Design QA, verifying that developers accurately implement the visual and interaction specifications, and Post-Launch Optimization, making iterative improvements based on real user data to enhance usability and performance. ⚠️ Just сontact me here right now and I will answer you within 5-15 minutes

I design product interfaces and visual systems for SaaS teams and startups. My work is structured in Figma, built in a way that can grow over time, and prepared so developers can implement it without confusion or repeated questions. I have earned more than $50K and completed over 1,800 hours on Upwork. I’ve worked closely with product teams in SaaS and healthcare, leading UX and UI design from the first wireframes to the final handoff. I create component libraries that cover all states, set up design token systems across multiple products, and deliver interfaces that are clear and easy to build. What makes my approach different is my strong focus on visual quality and branding. The systems I design are not only functional but also consistent and well thought out. Components are not just usable—they look intentional. When a product also needs marketing materials, pitch decks, or brand guidelines, I can create them using the same visual system, so everything stays consistent. One example of my work is a group of five connected SaaS products in healthcare. These included patient scheduling, doctor search, employee portals, homecare solutions, and internal dashboards. I led the UX and UI design across all of them, building the component library, defining the design tokens, and designing every screen with full state coverage, all organized clearly in Figma for handoff. Here is what I deliver: -UX flows, wireframes, and interactive prototypes -High-quality UI design for web and mobile, including SaaS dashboards, MVPs, and redesigns -Complete design systems with components, variants, tokens, and all UI states (such as error, loading, and empty states) -Brand identity with clear guidelines, including logo, typography, and color systems -Figma files that developers can use directly, with no missing elements or unclear layers -Marketing materials such as social media content, ads, banners, pitch decks, and presentations -AI-supported workflows for faster prototyping, generating variations, and refining copy within the UI Clients choose to work with me because I combine product thinking with strong brand consistency in one place. I collaborate directly with developers and understand what makes a Figma file easy to use and what causes problems. I communicate clearly at every step, so there are no surprises at handoff. I also approach every project as a long-term collaboration, not just a one-time job. If you already have designs, a brief, or a product challenge, you can share it with me. I will explain where I would start and how we can move forward.
