Collaborative desktop word processor with live six-language translation, real-time multi-user editing over WebSockets, and Azure SQL persistence. Built in JavaFX with an embedded Quill.js rich text editor.

• Embedded Quill.js in a JavaFX WebView, bridging Java and JavaScript for rich-text editing, clipboard integration, and .docx export via Apache POI
• Engineered real-time multi-user editing over WebSockets with delta-based synchronization (~80ms latency), live cursors, user presence, and cross-network collaboration
• Integrated Azure Translator for translating six languages live, preserving formatting through delta-aware text batching and source restoration
• Secured document storage with Azure SQL-backed authentication, BCrypt password hashing, and JDBC prepared statements, so each user's documents persist across sessions, stay private to their account, and save automatically

Real-time LLM routing dashboard with SSE streaming. Visualizes prompt complexity, model selection, confidence, latency, and escalation decisions across a three-tier, heuristic-based routing system.

• Built an interactive LLM orchestration dashboard for a three-tier, heuristic-based routing system that scores prompts 0-100 and escalates to a stronger model when confidence falls below 0.75, surfacing each routing decision
• Implemented token-by-token response streaming via Server-Sent Events (SSE), rendering live routing metadata and latency metrics alongside model outputs
• Derived routing-efficiency metrics and model-tier distributions from structured FastAPI responses to quantify cost-quality tradeoffs in model selection
• Integrated three REST endpoints (standard, streaming, and analysis-only) with responsive loading, error, and retry states for asynchronous model execution

Chrome extension with 50+ installs and 5-star rating - injects reusable email templates into Gmail and Outlook using MutationObserver for SPA compatibility.

• MutationObserver for dynamic DOM updates in SPA environments
• Local persistence via Chrome Storage API with async CRUD operations
• Modular content script separating DOM injection from state management

Graphical Wordle recreation built in Python - six attempts to guess a five-letter word with color-coded tile and keyboard feedback.

• Full Tkinter GUI with centered window, letter input, and on-screen keyboard tracker
• Real-time tile updates with green/yellow/gray feedback validated against a 5-letter dictionary
• Win/loss screens with custom icon assets, Pillow image rendering, and Play Again flow
