At AIonOS, I built the concurrency layer for a FastAPI service that processes airline fare rules, using separate limits for incoming requests and LLM calls. I also added request-scoped response caching and automated cross-category mismatch correction.

I built W3:Terminal, a Rust and Tokio crypto arbitrage scanner that streams normalized prices from exchanges and Solana DEXs to a live dashboard. My other projects include an Anchor smart contract and Rust indexer for AetherNet, and a secured full-stack social app, YAP.
