What I typically work on: • Migrating React apps to Next.js (Pages or App Router, depending on the project) • Improving SEO and Core Web Vitals • Setting up SSR and modern data-fetching • JavaScript to TypeScript rewrites for safer, more maintainable code • Cleaning up legacy React code and technical debt Once the app is stable, I also help teams automate internal workflows using AI to reduce manual work and improve efficiency. I value clear communication, realistic timelines and production-safe solutions.
