Khader Hassan Hwaijeh

Software Engineer · Full-Stack Developer · Mobile & Web Applications · Damascus, Syria

Full-stack software engineer who ships products to production and keeps them running. I build, deploy and personally operate four production systems on self-managed VPS infrastructure: a university services platform officially adopted by Al Sham Private University's housing department, a marketplace I founded from scratch, a legal foundation's bilingual public site, and a classifieds platform in pre-launch. Day to day that means Flutter mobile development, Laravel REST backends, Linux and Nginx operations with monitoring and automated backups, and AI automation with n8n.

Production systems

Live platforms with real users, running on infrastructure I provision and maintain myself.

مطمورتي

Creator & Sole Developer

Arabic money tracker for everyday life in Syria — expenses and income in Syrian pounds and dollars, fully offline, and your data never leaves your phone.

• Track expenses and income in new Syrian pounds and US dollars — type amounts in old or new pounds and the app converts them (100 old = 1 new).
• Record exchanges between dollars and pounds; an "All" view totals everything in pounds at each day's own rate.
• Works fully offline with no account: the app has no internet permission at all, so your data never leaves your phone.
• Back up to an Excel file and restore it later, merging with or replacing what is on the phone.
• Released as a signed Android app and, from the same code, an iPhone web app that installs from Safari and works offline — backed by 240 automated tests plus browser tests in Chromium and WebKit.
