Web Development & Sites in Belgium — Rui Codex

We create more than just websites; we build digital growth platforms.

Using React, Next.js, and ASP.NET Core, we engineer fast, secure, and mobile-first web experiences that rank high on Google and convert visitors into loyal customers.

From corporate presence to complex self-service portals.

Use Cases

Multilingual Corporate Websites

Fast, accessible company sites in Dutch, French, English, and German with per-language SEO, structured data, and a CMS your marketing team can actually use.

B2B Portals & Dealer Platforms

Authenticated portals where dealers and business customers place orders, check stock and pricing, download documents, and track their account — wired to your ERP.

E-Commerce Storefronts

Conversion-focused webshops with payment, shipping, and accounting integrations — built to load fast and rank well from launch.

Custom Web Applications

Browser-based tools that replace spreadsheets and paper — booking, quoting, planning, and reporting applications tailored to the workflow.

Performance & SEO Engineering

Core Web Vitals remediation, structured data, and rendering fixes for existing sites that look fine but score badly and rank worse.

Admin Panels & Content Systems

Management backends with role-based access, workflow states, and audit logs — the operational half every good website needs.

3

Build With Performance Budgets

Development against hard budgets for load time, script weight, and accessibility — measured on every merge.

4

Metadata, structured data, hreflang, and per-language content wired in and validated with real testing tools.

Controlled go-live with analytics, Search Console, and a prioritised backlog of post-launch improvements.
