We designed and built a fully bilingual (English/Arabic) manufacturer platform in an editorial-technical style, with structural RTL support so Arabic readers get the same depth, not a mirror image. It spans the full commercial funnel: a six-family product catalog (from LV switchboards to smart grid) with per-family specification pages and request-a-quote flows, a documented library of Saudi project references, industry-sector pages, a careers portal with CV upload, investor and insights sections, and PDPL-compliant contact and consent handling. A Go backend (PostgreSQL, JWT auth) powers a self-serve React admin console, so TEPCO's own team edits content, products, projects, and leads in-house. The Next.js frontend is server-rendered for SEO and falls back to static content when the backend is unreachable.
