Senior Mobile Engineer · iOS & Flutter Cairo, EG · Available Q2 2026

Building mobile products that feel inevitable.

I'm Salah — a senior mobile engineer with seven years shipping production iOS and Flutter apps across telehealth, logistics, gaming, and enterprise. I set the architecture before scaling the team, write code that becomes the template others adopt, and treat every detail as a chance to make the product feel right.

01 — Background

A quiet obsession with how mobile feels.

Cairo · Remote-first

Salah Nahed Mobile Engineer

I started writing iOS apps in Swift seven years ago and never stopped caring about the small things — animation curves, navigation transitions, how an app feels in the first three seconds.

Today I split my time between native iOS and Flutter, with deep work in Clean Architecture, state-machine testing, and modular codebases that scale beyond the founding engineer.

I've shipped teletherapy platforms with Agora video, logistics apps used daily by thousands across Saudi Arabia, and authored open-source frameworks now used by other teams — Flutter Bond and AppRouter-UIKit.

Lately I've been building AI-augmented mobile workflows — multi-agent systems, Claude-powered QA pipelines, and custom Claude Code skills that make the development loop tighter.

06 — Philosophy

How I think about shipping.

Principles, not rules
01 / Architecture

Set the standard before you scale the team.

I write the architecture, theme system, and coding standards before onboarding the second developer. The first feature is a reference implementation — the next ten follow the pattern.

02 / Testing

If it isn't tested, it isn't shipped.

State machines deserve exhaustive coverage. Memory leaks deserve assertions. Golden tests catch the regressions PR review can't. I treat XCTest and widget tests as production code.

03 / Craft

The product is in the transitions.

Users don't read your architecture diagram — they feel the 16ms frame drop, the awkward keyboard pop, the navigation that goes the wrong way. Mobile UX is mostly micro-decisions.

04 / Mentorship

Lead first. Then delegate.

I ship one full feature end-to-end as a reference, then hand the next to a junior. They pattern-match against working code instead of guessing from a wiki page.

05 / Open Source

Extract what others will reuse.

Flutter Bond and AppRouter-UIKit weren't side projects — they were pulled out of real production codebases when the pattern proved itself three times over.

06 / AI Tooling

Treat the agent like a junior dev.

Plan-gated approval. No silent edits to production code. I caught Claude modifying source to make tests pass, then wrote the approval-gate rules to prevent it. Tools work best with guardrails.

07 — Writing
