About Yurii
I help startups, agencies, and product teams build reliable web and mobile applications using React, Next.js, React Native, and TypeScript.
With 7+ years of experience, I’ve worked on production-grade products across web and mobile, including SaaS platforms, dashboards, e-commerce flows, mobile apps, API integrations, authentication, payments, and performance improvements.
I can help with:
• Building MVPs from an idea, Figma, or existing requirements
• Developing React / Next.js web applications
• Creating React Native / Expo mobile apps
• Improving existing frontend codebases
• Fixing bugs, performance issues, and UX problems
• Integrating APIs, Supabase, Stripe, Clerk, Firebase, and other services
I’m especially useful when you need someone who can understand the product goal, move fast, communicate clearly, and deliver clean, maintainable code without unnecessary complexity.
