Problem

A real business site needs more than a static landing page: multilingual content, material catalogs, reference projects, quote requests, and admin-managed updates.

Contribution

Built a frontend/backend separated website and CMS with a custom brand mark, public pages, admin tooling, media metadata, and validated quote-request workflows.

Engineering

Implemented a Vite React 18 TypeScript frontend, Express API, Zod validation, Multer uploads, Helmet security middleware, PostgreSQL-ready persistence, and deployment split across Vercel and Render.

Outcome

Delivered a production-oriented system that can be maintained through an admin console instead of code edits.
