A full-stack telemedicine and appointment booking platform built with TypeScript, React 19, Express 5, and PostgreSQL. Features strict role-based access control (RBAC), database transaction-level locking to prevent double-booking and concurrency race conditions, Zod schema validation to eliminate untrusted injection vectors, and bilingual Arabic/English RTL support.

A native Wayland crosshair overlay daemon written in C (C99) using layer-shell with input passthrough. It bypasses legacy X11 security flaws (where arbitrary clients can snoop global keystrokes and mouse events) by adhering strictly to Wayland's isolated surface protocol, and catches SIGUSR1 to reload configuration dynamically in memory.

A terminal music player I built with Textual that streams tracks from YouTube Music while syncing Spotify playlists without Spotify Premium. It controls a background mpv daemon over a secure Unix domain socket, renders a 60 FPS spectrum visualizer via cava, and connects to MPRIS 2 for desktop media keys. Published on PyPI and featured on Awesome TUI.

A Discord-to-Minecraft synchronization bot and Paper plugin in Java 21. Prevents player identity spoofing by resolving immutable Mojang UUIDs against official REST APIs, enforces privilege isolation by restricting administrative commands to secure ticket channels, and maintains tamper-evident audit logs.

A Discord bot I made that queries multiple tier list APIs to check verified player ranks, resolving Minecraft usernames to permanent Mojang UUIDs to prevent name-spoofing and rank tampering.

A Brave and Chromium extension I wrote that forces JetBrains Mono across all webpage text. It walks DOM text nodes and observes mutations to pierce Shadow DOM trees and style dynamic SPAs without clobbering icon fonts, SVG glyphs, or code blocks.

My personal Arch Linux and CachyOS setup, tuned for low input latency with tearing and direct scanout for full-screen games. Centered around a dark Oxocarbon palette with an automated symlink installer and rollback script.
