# Ivan Kordonets > Product Designer · UX/UI Engineer (React, Vue, Angular) | Building 0→1 Products & Design Systems in Code Location: San Francisco Bay Area, United States Profile: https://flows.cv/ivankordonets Product designer and UX/UI engineer building scalable, component-based products that connect design with clean, maintainable code. Experienced in React, Vue, and Angular, delivering complete design systems and Storybook libraries for real production use. Combines design vision with front-end architecture — creating reusable components, defining UI logic, and building design systems that evolve with the product. Integrates Storybook and Chromatic for automated visual testing, ensuring every change is pixel-perfect and tracked across builds. Strong believer in component-driven development: every UI element exists as a verified, documented component with visual diffs, making collaboration between designers and developers faster and more reliable. This workflow turns design into living code — reducing errors, improving consistency, and helping teams scale their products confidently. Passionate about making design measurable, maintainable, and alive in code. ## Work Experience ### Product Designer & Frontend Engineer · UI Systems, Storybook Libraries, SaaS UX @ Stealth Startup Jan 2024 – Present | United States • Spearheaded 0→1 product development, designing and launching a new loan flow in React that increased loan volume by 30% in 6 months. • Built the first version of the company’s mobile app with React Native, delivering iOS and Android support to thousands of users. • Created a design system from scratch with 100+ reusable components in Storybook, improving consistency by 300% and enabling rapid iteration. • Set up Posthog, Google Analytics, and Meta Pixel for real-time insights, campaign tracking, and conversion optimization. • Refactored critical flows to improve upload speeds by 300%, replaced outdated packages, and created an internal npm UI library for cross-product reuse. • Integrated WordPress and LinkedIn for marketing automation and lead generation, with full tracking through Google Tags. ### Product Designer | UX/UI Design Engineer specializing in React/Vue @ Virtuozzo Jan 2022 – Jan 2024 | United States • Product Designer & UX/UI Developer: Specializing in integrating cloud solutions like Virtual Machines, PaaS, IaaS, and Kubernetes within a Cloud Management Platform. • Front-end Development Expertise: Developed component libraries using React, Storybook, and Chromatic, and crafted intuitive dashboards with Vue.js. • Strategic Leadership: Led the design integration of PaaS (Jelastic), IaaS (OnApp), and Virtuozzo (VHI) into a unified Virtuozzo Cloud Management Platform. • Revenue Optimization: Designed a new wizard for creating virtual machines, resulting in a 4x revenue increase within 6 months. • Feature Expansion: Launched User Management, Teams, Infrastructure, Billing History, Dashboards, SSO, 2FA, and Kubernetes, leading to a 3x revenue increase and a 5x client expansion. • Design System Implementation: Implemented a design system with 200+ components in Storybook, improving development efficiency by 300% and reducing bugs and time efforts by 260%. • Market Growth Initiatives: Implemented a new object storage solution, attracting 4x more customers and expanding the market footprint. ### Product Designer | UX/UI Developer React/Vue @ InsightCat Jan 2021 – Jan 2022 | United States • Visionary Product Designer & UX/UI Developer: Spearheaded the development of products from inception to execution, expanding the team to 40 professionals. • User Experience Strategy: Crafted and executed strategic planning and roadmaps, collaborating closely with founders to ensure alignment with business objectives. • Successful Product Launches: Led design efforts from scratch to delivery for various components including Logs, Synthetic, Dashboards, APM, Incident Timeline, Alerts, Insights, Anomalies, and Billing, resulting in a significant $3 million investment. • Efficient Design Systems: Managed the implementation of a new design system, enhancing platform efficiency and reducing delivery time by 4x. • Cross-Functional Collaboration: Collaborated with marketing and sales teams to create designs for presentations, exhibitions, social media, and Horeca. • Award-Winning Designs: Recognized with 4 International design awards for innovation and excellence in product design. • Expertise in UX/UI Development: Proficient in developing user interfaces using React and Vue.js, ensuring seamless integration and functionality across platforms. ### Product Designer @ OpenVPN Inc.
