Frontend Developer focused on React, JavaScript, HealthTech, AI-powered web applications, and automation workflows.

I build practical, human-centered products with clean frontend architecture, real user workflows, responsive UX, and secure data handling. I also build focused AI-style workflow prototypes that connect frontend development with business process automation.
