Message

I'm developing Modexa, an offline POS system with product, inventory, sales, and customer workflows. It supports barcode scanning, receipt printing, role-based access, and Arabic and English.

For Modexa, I've implemented business reporting for sales periods, stock movement, top-selling products, and profit estimation. I've also worked on SQLite optimization, database concurrency, and Livewire performance.

I built and deployed CinemaFlix, a responsive movie web application that retrieves information through the TMDB API, and developed database-driven social media and e-commerce web projects. At 42 Beirut, I completed intensive programming training centered on C, Linux/Ubuntu, Bash, Git, and command-line development.
