I’m Mohamed — a full-stack and frontend engineer who turns complex requirements into fast, polished web products, end to end: from the database and APIs to interactive interfaces. My specialty is the Salla ecosystem: apps and custom themes, built with agencies.

CODE YOU CAN Feel
Great software isn’t only correct — it feels right. I care about the details users notice without knowing why: instant responses, smooth motion, and interfaces that make complex things simple. That’s the standard I build to, on every project.
Merchants I’ve worked with across fashion, beauty, electronics and more.
Live stores running themes I’ve built.
Custom and marketplace themes shipped for Salla and Zid.
I bridge engineering and experience — designing the logic, building the product, and shipping it fast.

From requirements to production.
A clear process, so you always know what’s happening and what comes next.
Discovery
We start with your goals, users and constraints, and turn them into clear, prioritized requirements.
Architecture & Planning
I design the data model, the system and the user flows before writing the first feature.
Build & Iterate
Development in short cycles with a live preview link, so you see progress and give feedback as we go.
Launch & Support
Production deployment, monitoring and performance tuning — and I stay with you after launch.
