I build and ship web and mobile products.

I'm Mohamed Berrima, a freelance full-stack developer. I take products from idea to the App Store, Google Play and production servers, with AI at every step, then keep them running.

Mobile work

Apps that shipped to real stores.

Real screens from real releases. Nothing here is a mockup of something that was never built.

How it runs

From first message to live, without the mystery.

No six-week discovery. A decision fast, a fixed scope, something running every week.

01
Intro call
20 min, this week
You describe the problem. I tell you straight away whether I'm the right person.
02
Scope & fixed quote
Within 48h
What ships, in what order, on which dates, for what price. No hourly billing, no surprises.
03
Weekly shipping
Every week
A running build in your hands each week, not a status update.
04
Handover & support
On delivery
Code, docs, store and server accounts in your name. Plus a support window.

I reply within one working day. If I'm not the right fit, I'll say so on the first call rather than take the work.

Stack

Proven foundations, AI at every step.

What I build with today. A foundation that ships fast and stays maintainable, and AI to code, test and ship faster. The decisions stay mine.

Before the code

I started as a designer. 2020 – 2022

Two years of logos, identities and campaigns before engineering became my main job. I still take design projects: logos, brand identities, social media visuals.
