I am a Senior Front-End Engineer with 7+ years of experience building production React and Next.js applications for distributed remote teams, with hands-on backend experience in Node.js and .NET. I distributed frontend teams across EMEA and APAC regions since 2023, maintaining consistent daily overlap and async handoffs to keep delivery uninterrupted across time zones.
