Kyiv, Ukraine - 7:24 am local time
📊 A Nextjs TypeScript Healthcare platform i revamped increased user engagement and reduced frontend load times by 35%.
I’m a Senior TypeScript Next.js engineer with 10 years experience. I've shipped fast, scalable, accessible web applications with TypeScript, Next.js and React . I’ve built 25+ full-stack applications, 50+ high-performance Landing Pages, and 5+ scalable SaaS Development. I can act as a FrontEnd Architect and Tech Lead.
I design clean component architectures, robust state management, and reliable API integrations that scale. My work spans event/ticketing platforms, real-time crypto dashboards, secure enterprise admin panels, and full-stack SaaS (NestJS + GraphQL + PostgreSQL). I care about accessibility, performance optimization, and maintainability.
