I designed and built a complete trading and research platform that executes automated strategies and replays historical markets with deterministic accuracy.

The system records live market data tick-by-tick, reconstructs order books, and runs the exact same strategy, execution, and portfolio logic in both live trading and backtests — ensuring results are directly comparable and operationally reliable.

It includes full trading infrastructure: real-time data ingestion, execution engine, order management, portfolio accounting, and research tooling for strategy development and optimization.
