Crafted for Performance & Security.

Project Overview

DuelWord re-imagines competitive word puzzles as an adrenaline-fueled head-to-head duel. Rather than taking asynchronous turns over hours, players match up live to solve symmetric or custom puzzle boards simultaneously.

The game features dynamic board sizes spanning 4, 5, 6, 7, and 8-letter secret words, real-time opponent progress mirrors, private custom matchmaking rooms, tournament brackets, and a skill-based MMR rating system.

Technical Highlights

• • Mobile Architecture: Built in React Native / Expo with TypeScript for 60fps animations and fluid keyboard haptics.
• • Real-Time Sync: Distributed Node.js & Socket.IO WebSockets backed by Redis pub/sub.
• • Data & Verification: Server-verified solves, PostgreSQL match persistence, and automated offensive word moderation.
• • Compliance: Integrated Google Play Billing and Apple StoreKit with automated server-side verification.

Project Overview

Undercover Drop delivers true zero-knowledge file encryption. Built on the principle that files should never leave a user’s device in an unencrypted state, all cryptographic operations occur directly inside the user's browser via native Web Crypto APIs.

Users can encrypt files locally with custom passwords without creating an account or transmit encrypted payloads securely across the web where only the intended recipient holding the cryptographic key can unlock them.

Technical Highlights

• • Zero-Knowledge: Server infrastructure never receives, holds, or has mathematical access to unencrypted file bytes or keys.
• • Military-Grade Ciphers: Standardized on AES-GCM 256-bit authenticated encryption with PBKDF2 key derivation.
• • Multi-threaded Workers: Background Web Workers process large file chunks smoothly without locking the browser UI thread.
• • Zero Tracking: Strictly no third-party behavioral analytics or personal data monetization.
