A short introduction
I'm Abdullah Omar, a Backend Engineer with +1 years of experience in Node.js/NestJS Backend development, focusing on designing and building scalable, secure APIs, database architecture and full-featured backend systems.
I am passionate about software engineering best practices, solving real-world problems, and continuously expanding my technical expertise while contributing effectively in collaborative teams.
A few projects where engineering detail meets a real human need.
Hackathon platform
Architected a full hackathon management platform covering team registration, organizer review and approval workflows, automated acceptance and rejection notifications, QR-based check-in, final project submission, and bilingual English/Arabic support.
Desktop application
Offline ElectronJS desktop app for doctors to manage patient records, search a medicine catalog, and generate print-ready PDF prescriptions with full RTL/LTR support and per-patient history tracking. Currently in active daily use in a physician clinic.
Full-stack Solution
An AI-powered attendance system that replaces manual roll calls with a single classroom photo, automatically detecting, identifying, and marking students present. Built with RetinaFace for detection and ArcFace for facial recognition via feature embeddings, achieving 97% accuracy for classes of 40–45 students with one button press.
