An open-source system that transfers files between two devices using only a screen and a camera, with no Wi-Fi, Bluetooth, NFC, or internet required. Built a custom Fountain Code encoding engine with a belief-propagation decoder for lossless reconstruction, and a parallelized Web Worker pool to generate and decode QR frames off the main thread for real-time transmission. Packaged as a native Android app via Capacitor.

A full-stack route optimization app built with Next.js App Router and TypeScript. Integrates Leaflet.js with OpenStreetMap for interactive map rendering, with OSRM-powered turn-by-turn routing, a custom polyline decoder for color-coded overlays, and a debounced SearchBox component with dynamic map fitting.

A 3D drone simulator with physics-based flight (velocity, acceleration, damping) in procedurally generated environments. Gesture-controlled via MediaPipe + OpenCV hand tracking, running smoothly at 60 FPS with a live HUD for altitude and speed.

An educational Android app demonstrating over-privileged app behavior and background security vulnerabilities. Built with a Flask backend polling system that triggers remote commands, illustrating real-world permission misuse and user awareness gaps.

A responsive full-stack platform managing club events and member interactions, deployed on Vercel for high scalability and uptime. Includes secure user authentication and a robust database layer for real-time event updates.

A real-time, touchless human-computer interaction system using MediaPipe hand tracking to render on-screen strokes from finger movements, with frame-smoothing in OpenCV for a jitter-free, fluid drawing experience.
