At Deutics Global (Camzify), I owned 20+ production React components and cut unnecessary re-renders by about 40%. I also integrated 15+ REST APIs across three role-based dashboards.

I’ve independently shipped full-stack projects, including an embeddable AI customer-support widget using Next.js, Google Gemini, and Scalekit. I’m currently building the backend for a travel-planning platform with JWT authentication and role-based access control.
