I build real-time systems for financial markets and blockchain infrastructure. Most of my work revolves around algorithmic trading, prediction markets, and low-latency backend systems. I’ve implemented financial models from scratch in Python, then rewritten performance-critical components in Rust for faster execution and tighter concurrency control. I’ve built systems that coordinate multiple live market feeds simultaneously using Tokio, async tasks, shared state primitives, and message-passing pipelines. On the blockchain side, I work directly with EIP-712 signing, conditional token operations, and automated settlement flows. I’m comfortable building against smart contracts at the protocol layer rather than relying entirely on abstractions and SDKs. I’ve also built data-driven automation systems using vector search, live news ingestion, and LLM pipelines for market analysis and execution support. Outside trading systems, I build terminal-based monitoring tools, cross-exchange aggregators, signal pipelines, React dashboards, and Streamlit applications for analytics and visualization.
