Full Stack Engineer
I'm a software engineer working across full-stack development and high-performance systems. At Meteora Capital, I build and run an MCP server that gives Claude 55 tools across the firm. Before that, at Smartleaf, I automated cash sweeps and validated a PostgreSQL upgrade for reporting that serves $110B in AUM. In Rust I built a matching engine that submits orders in ~113 ns.
My dual degree in Computer Science and Fintech from Northeastern drives my interest in where finance meets technology: trading infrastructure, payment systems, and the data pipelines that power financial decisions.
Price-time-priority matching engine with partial fills and lazy cancels, behind a multi-symbol Axum HTTP and WebSocket exchange service with a Next.js live order book. Benchmarked ~113 ns order submission, 200k–500k orders/sec, and sub-100 µs WebSocket fan-out.
Real-time stock analysis app with advanced technical indicators (RSI, MACD, Moving Averages). Built with Python, Dash, and Plotly with standalone executable distribution.
Multi-source business news aggregator using web scraping and rotating proxies. Features REST APIs and MongoDB storage for persistent news data.
