(Who we are)

SitexPrime is a small, senior studio. We plan, design and build digital products end to end, which means no handovers lost in translation and no surprises the week before launch.

Every engagement starts with the same question: what should this site actually do for the business? Everything after that — the layout, the type, the code — answers it.

Our Team

Nine people, four time zones, one shared standard of finish.

(Selected work)

Products we designed, built and still run

Three live products, each one taken from an empty page to a paying audience. Brand, interface, code and infrastructure — all of it ours.

Veylcast home page — encrypted video delivery platform

SaaS product Live veylcast.com

Encrypted video delivery for people who sell what they film

Ship video that refuses to be copied.

A video hosting and delivery platform for anyone whose video is the product — course platforms, film libraries, corporate training. Every file is encrypted and served through short-lived links tied to a single viewing session, so a copied URL is dead before it can be shared. It ships as a complete product: encoding pipeline, customer dashboard and embeddable player.

An Arabic news publication, with the whole newsroom behind it

Arabic news, published properly.

A complete Arabic news site — politics, economy, sport, culture, science and technology — built right-to-left from the ground up rather than mirrored from an English layout. Behind the reading experience sits a real newsroom: an editor's panel, a newsletter, social publishing, and an AI import pipeline that always stops at a human editor before anything carries the masthead.

Certificate verification that asks the organisation that issued it

Verified means the issuer said so. Nothing else counts.

There is no universal registry of certificates, so AskIssuer asks the only party who can answer: the organisation that issued the document. Upload a PDF, a scan or a phone photo — one or a hundred — and each file is read, its QR code decoded and its verification code checked against the issuer's own records. Anything that cannot be confirmed is reported as needing review, never as fake.

Qitaf – Florist Studio & 3D Bouquet Builder HTML Template

A trilingual (EN/AR/DE) 17-page florist storefront built around a real-time 3D bouquet builder: the customer picks the size, flowers, greenery, wrap and ribbon, and the arrangement assembles itself in WebGL before anything is cut. Mobile-first, with a fully mirrored RTL layout that the 3D studio mirrors with it.
