Momin J.Abusaada

Senior iOS Engineer

Swift, SwiftUI, UIKit, CI/CD & AI-Assisted Development | 200+ Apps Shipped, One at 1M+ Concurrent Users

About

1M+ Concurrent Users. 60% Less CPU & Memory. 14 Years Spent Making Sure Swift Code Didn't Buckle Under Real Load.

What kept me in this job was closing the gap between "it works on my machine" and "it holds up for a million people"—release by release.

That mindset shaped my work as Lead iOS Engineer on Madrasati (مدرستي), Saudi Arabia's largest education app, engineered for speed, accuracy, and reliability under real classroom-scale traffic. I carried the same discipline across telecom and fintech-adjacent products throughout my career.

What I Brought to Every Team

  • Native iOS Expertise: Swift, SwiftUI, UIKit, Objective-C, RESTful APIs, MVVM
  • Performance Engineering: Improved app performance by ~40% and reduced CPU & memory usage by ~60% across production applications.
  • Release Engineering: Built CI/CD pipelines that reduced deployment time by 40%+, delivered bi-weekly releases, and maintained 80%+ test coverage.
  • Leadership: Led a 5-engineer iOS team, mentored 10+ interns, and contributed as a core engineer on a multi-engineer product team at Foothill Technology Solutions.

Freelance Experience

As a freelance iOS developer, I also designed and shipped applications end-to-end for clients:

  • FarmGO — Geolocation-based grocery ordering.
  • Smart Gym Coach — AI-powered training & nutrition.

Both applications were built with SwiftUI on iOS 26.

Owning client products from concept to delivery—combined with hands-on experience using Claude Code and modern AI-assisted engineering workflows—kept me focused on building scalable architectures, not just writing code.

Currently Open to Opportunities

I'm currently open to Senior iOS Engineer roles, especially with teams that value performance, clean architecture, and shipping fast without breaking things.
