Low-latency local order book for Binance Spot — combines a REST snapshot with the diff-depth WebSocket stream to maintain a provably correct real-time book on a core-pinned, lock-free hot path, with a live per-symbol health dashboard.

C++20 stochastic-volatility pricing & risk platform — Heston FFT calibration with AAD-accelerated Greeks, American Monte Carlo, a portfolio scenario engine, and live L2 ingest, every number validated against QuantLib across 225 tests.

Idiomatic Go web3 event gateway — ingests on-chain swap logs from Solana and Ethereum over WebSocket, normalizes them into one event schema, and fans them out over WebSocket + Prometheus using goroutines, channels, and context.
