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.

THE JOURNEY
Every idea arrives tangled. It leaves as a product.
Nine steps, the same on every project. Follow the red thread: you always know where we are, and what comes next.
I 01 of 09
Discovery
You askI have an idea. I’m just not sure how to say it.
The smith answers The War HornBefore any blade is forged, the smith listens. The warrior sounds the horn and tells of his battle; I listen for the goal behind it.
A free 15–30 minute call, or a written brief if you prefer. I listen for the goal behind the request.
- You get
- A clear goal
- Terms
- Free, no commitment
II 02 of 09
Analysis
You askIs this even the right way to build it?
The smith answers The HelmA smith studies the warrior’s kit before he forges a thing: what earns its weight, and what only slows him down.
I study what you asked for and what your product actually needs, and flag what can save you time or money.
- You get
- Honest recommendations
- Terms
- 1–2 days
III 03 of 09
Planning
You askHow long, and what exactly will I get?
The smith answers The Dagger & the MapBattles are won on the map first. The dagger pins the plan down before any iron is struck.
Scope, architecture and user flows, mapped out before a single line of code is written.
- You get
- A plan you can read
- Terms
- 2–4 days
IV 04 of 09
Proposal
You askCan I trust this on paper?
The smith answers The SwordOaths were sworn on the blade. Hand on steel, the terms are sealed.
One clear document: scope, deliverables, timeline and price. Then a contract and an NDA.
- You get
- Proposal, contract, NDA
- Terms
- 50% to start
V 05 of 09
Design
You askCan I see it before it’s built?
The smith answers The ShieldEvery warrior chooses a crest. The shield is how you’re known across the field, so it is drawn before the steel is poured.
Designed in Figma, or built from your own design. Nothing is coded until you approve it.
- You get
- An approved design
- Terms
- Approved before code
VI 06 of 09
Development
You askIs anything actually happening?
The smith answers The HammerStrike after strike on the anvil. You watch the blade take its shape while it is still hot.
Built in short cycles with a live preview link, so you watch it take shape instead of waiting.
- You get
- A live preview link
- Terms
- Updates at every stage
VII 07 of 09
Testing
You askWhat if something breaks?
The smith answers The Proven BreastplateArmourers fired at a breastplate before they handed it over. If it held, they stamped it with a proof mark. I strike the product before the market does.
Real devices, real data, edge cases and speed. Then your feedback, applied.
- You get
- Two revision rounds
- Terms
- Small changes, same scope
VIII 08 of 09
Launch
You askIs it really mine now?
The smith answers The BannerWhen the steel is ready, the warrior raises his banner and rides out. It says: this is mine now.
Deployed, handed over and explained. The source code is yours.
- You get
- Code, files, docs
- Terms
- Balance before handover
IX 09 of 09
Support
You askAnd after launch, am I on my own?
The smith answers The GauntletA true swordsmith doesn’t vanish after the battle. His hand stays on the hilt: sharpening, mending, guarding.
I don’t vanish after launch. Free support while the product settles, then optional monthly care.
- You get
- Free support
- Terms
- 1–4 weeks, by size
The oath is kept.
Your project could be the next one I walk through, start to finish.
