Mobile products,
engineered to last.
I'm Haithm — a mobile engineer who ships. Document engines, photo tools and offline-first apps built in Flutter, with the architecture, monetization and polish production demands.
Built, shipped, and maintained
Not demos — live products on the App Store and Google Play, each one owned end to end: architecture, UI, monetization, localization and releases.
Vivy PDF
A complete PDF toolkit with an intelligent scanner: precision edge-detection, automatic cropping and a dedicated ID-card mode. Merge, split, compress, sign, lock and watermark — fifteen tools, every one of them running entirely on-device.

Vues
Make any photo fit: exact dimensions, exact file size. On-device face detection aims the crop for passport and profile photos so the head lands where the specification demands, and a byte-precise encoder hits limits like "under 200 KB" on the first try.

Adhkari
A minimalist companion for Adhkar and Tasbeeh with an elegant, distraction-free interface — engineered to work completely offline.

What I do
I build mobile products the whole way: from the first architecture decision to the store listing. My work is heavy on on-device processing — PDF engines, image pipelines, face detection — where performance and privacy are the product, not a feature.
Beyond code, I handle what shipping actually requires: monetization that respects users, localization into 16 languages with full RTL support, store compliance, and the release discipline that keeps ratings high.

Let's talk
A question about one of my apps, a bug report, or a project you want built — every message lands in my inbox, and I read all of them.
