01About

Engineering-grade craft. Designed for the people you're trying to win.

I'm a computer engineer who has worn the founder, the marketer, and the developer hat — often at the same time. I've run media buying campaigns, shaped products from raw idea to launch, and built the websites underneath them. From clean static landing pages to full-scale e-commerce platforms, I make sure the stack, the speed, and the story all line up.

Most of my work has been with founders and brands across Saudi Arabia, the UAE and the wider Gulf, with select projects in Europe. I care about the same things they do: real performance, search visibility, clean conversions, and a site that loads instantly even on a phone in the back of a Riyadh taxi.

02Services

What I actually ship. No buzzwords, no agency slowdown.

Pick one or stack a few — most clients come for a website and stay for the system around it.

01

E-commerce & Shopify

Full Shopify builds — from theme customization to headless Hydrogen storefronts. Bilingual EN/AR, regional payment rails, and fast on a 4G phone in Riyadh.

  • Shopify Liquid + Hydrogen
  • EN / AR bilingual + RTL
  • Stripe / regional gateways
02

Web apps & custom CRMs

Custom dashboards, internal tools, and multi-tenant CRMs. Built for agencies and operators who outgrew off-the-shelf SaaS and need something that fits how they actually work.

  • Multi-tenant architecture
  • Auth + RBAC + audit logs
  • Postgres + Next.js
03

Mobile applications

Cross-platform mobile apps with a full CMS admin behind them — from civic voting platforms to consumer products. iOS and Android from one codebase.

  • React Native / Expo
  • CMS admin panel
  • Push, auth, payments
04

Landing pages & marketing sites

Twenty-plus landing pages shipped across the Gulf and Europe. Page-speed obsessed, SEO-clean, and built to deserve the traffic you send.

  • Lighthouse 95+
  • A/B testing ready
  • CMS or static
05

Paid media & growth

End-to-end ad management on Google, Meta, Snapchat, and TikTok. I've spent client budgets and built the funnels underneath them — creative, landers, and tracking included.

  • Google · Meta · Snap · TikTok
  • Creative + landing tests
  • Funnel + cohort analysis
06

Server-side tracking (sGTM)

Recover the signal you've been losing to iOS 17, ad-blockers, and cookie deprecation. Server-side GTM and Conversions API parity for stores serious about ROAS.

  • sGTM deployment
  • Meta CAPI + iOS-17 recovery
  • Measurable ROAS uplift
03Process

From first call to launch in three to six weeks.

No 12-week agency timelines. No five-person account team between you and the keyboard. You talk to the engineer, every step.

  1. 01Discover
    Step 1 of 5

    Audit, brief, and brutal honesty.

    Quick discovery call, then a deep look at your current site, traffic, and competitors. I tell you what I'd actually do — even if it's ‘keep what you have.’

  2. 02Architect
    Step 2 of 5

    Stack, scope, and a fixed price.

    I scope features, pick the stack, and lock the price. No surprise invoices, no scope creep — what we agree on is what gets built.

  3. 03Design & build
    Step 3 of 5

    Designed in the browser, shipped daily.

    I design and develop in parallel. You get a live preview link from day one and feedback loops measured in hours, not weeks.

  4. 04Launch
    Step 4 of 5

    Speed-tested, SEO-ready, indexed.

    Pre-launch: Lighthouse, Core Web Vitals, schema, sitemap, analytics, pixels. Post-launch: monitoring and a 30-day support window.

  5. 05Grow
    Step 5 of 5

    Iterate against real numbers.

    Optional retainer to keep iterating — landing pages, A/B tests, ad funnels, content. Build, measure, repeat.
