I build backend APIs and full-stack web products with Node.js, React, and PostgreSQL.

I've built full-stack products including DermIntel, an AI-powered skincare analysis platform that evaluates ingredient-product compatibility against individual skin profiles.

I developed Next.js onboarding, dashboards, authentication flows, and Express APIs for DermIntel, backed by PostgreSQL, Prisma, and passwordless Google OAuth. I also built Live Book, a bookmark manager with metadata summaries, duplicate detection, a Chrome extension, Google OAuth, and Supabase row-level security.

During internships at Sasken Technologies and Adversity Solutions, I built C++ data-management and file-handling modules and developed RESTful invoicing APIs, PDF generation, database schemas, and backend logic for Invoicefy.
