Featured projects
MetaScientist (Meta_Scientist)
Python · MetaGPT · Monte Carlo Tree Search · Docker
Self-improving agentic research framework pairing LLM multi-agent orchestration with Monte Carlo tree search (MCTS) to automatically search quantum machine-learning algorithm pipelines. Integrates web search, task planning, and a dual-loop research cycle. Implementation framework behind the QTML 2025 paper; extends MetaGPT/SELA.
DDB Knowledge Agent (ddb-knowledge-agent-py)
Python · FastAPI · Server-Sent Events · Gemini · PostgreSQL · pgvector · Apptainer
Streaming RAG agent fusing pgvector similarity retrieval with PostgreSQL full-text search via reciprocal rank fusion (RRF). Includes ReAct tool calling, query-complexity-tiered model routing, semantic caching, and cost auditing. PostgreSQL runs under rootless Apptainer and is deployable on Docker-less HPC clusters.
GOAT Network Agent (goat-agent_demo)
Node.js · Express · ERC-8004 · x402
Autonomous Web3 agent registering an ERC-8004 on-chain identity and integrating with the x402 payment flow. Executes price tracking, conditional triggering, on-chain payment, and attested settlement end-to-end with no human intervention after launch.
optlab — Derivatives Pricing & Strategy Backtesting (optlab-py)
Python · NumPy · SciPy · Pandas · pytest · GitHub Actions · Black-Scholes · CRR Trees · Monte Carlo Simulation · Heston Model · Andersen QE · Raw-SVI
Pricing library and vectorised backtester built to test whether the variance risk premium survives transaction costs. Includes Black-Scholes analytic Greeks, CRR trees with American exercise, variance-reduced Monte Carlo with a 12.7× improvement via antithetic and control variates, Heston characteristic-function pricing and Andersen QE simulation, implied-volatility inversion, and raw-SVI and Heston surface calibration. Across 24 simulated 10-year paths, delta hedging lifted short-straddle Sharpe from 0.24 to 0.49, while frictions consumed 70% of gross P&L institutionally and all of it at retail. Included 102 model-validation tests covering convergence orders, Greeks versus finite differences, no-arbitrage bounds, and P&L versus a hand-computed ledger.
