Full-stack developer with 6+ years of commercial experience in React, TypeScript, Next.js, Node.js and NestJS. I build scalable web applications, complex interfaces, APIs, integrations and automation; I also troubleshoot and improve existing systems. My paid freelance work includes resolving a Google Merchant Center account suspension and restoring 123 approved products for an e-commerce client. I define a clear scope, deliver verifiable results, test thoroughly and communicate progress regularly. I work in English, Ukrainian and Russian.
