Quant focused on algorithmic trading systems, research tooling, broker and exchange integration, and performance-oriented engineering across Python, C++, Rust, and TypeScript.

• Quant credentials: CFA, FRM, CIIA, CFP
• Main interests:
  • Algorithmic trading
  • Trading strategies and strategy research
  • Backtesting and strategy engineering
  • Portfolio and factor analytics
  • High-performance systems
  • AI-assisted research and developer tooling

Over the last two years, my GitHub work has concentrated on three project ecosystems: the backtrader trading framework and its AI-native tooling, the fincore analytics family, and the bt_api multi-exchange SDK ecosystem.

Recent active contribution areas include:

• backtrader — framework maintenance, CI/CD, compatibility, documentation, and the AI-native workflow (MCP server, agent skills, web platform)
• bt_api_py — multi-exchange standardized API SDK, with 64 exchange adapters and 14 broker plugins
• backtrader_web — web-based strategy management and execution workflow
• fincore — unified quantitative performance & risk analytics toolkit

• Building production-friendly Python SDKs for quant workflows
• Researching and refining trading strategies across multiple market styles
• Exploring C++ / Rust / pybind / swig acceleration paths for quant infrastructure
• Connecting research, backtesting, live trading, and data tooling into a unified workflow
• Making quant systems easier to use with MCP / AI-native interfaces

• Trend following
• Mean reversion
• Momentum
• Breakout strategies
• Multi-factor stock selection
• Statistical arbitrage
• Market making
• Arbitrage and spread trading
• Event-driven strategies
• High-frequency trading research

Core framework and platform

• backtrader — high-performance Python backtesting & live-trading framework: 45%+ faster than upstream, 50+ indicators, tick-to-daily strategies
• backtrader_web — "AI for Investor" web platform (Vue 3 + FastAPI): research, AI strategy generation, backtesting, paper trading, live execution, and market-data management

AI-native workflow

• backtrader-mcp — local-first MCP server for AI-assisted strategy development: immutable datasets, private drafts, and bounded subprocess backtests via 30 typed tools
• backtrader-skills — offline author/review/test skills for AI coding agents (Claude Code, Codex, OpenCode)
• backtrader-agent — offline-first strategy-authoring agent runtime: StrategySpec validation, static review, hash-bound approvals

Performance rewrites and variants

• back_trader — the C++ version of backtrader (private)

• fincore — quantitative performance & risk analytics: 150+ financial metrics, portfolio optimization, Monte Carlo simulation, and attribution — the actively maintained successor to empyrical, pyfolio, and alphalens
• fincore_cpp — the C++ version of fincore

Core packages

• bt_api_py — Python SDK for multi-exchange integration with a standardized API
• bt_api_base — base package shared by all adapters
• bt_api_cpp — the C++ version of bt_api
• btapi — C++ API library: sync/async requests, WebSocket, and FIX
• bt_api_monitoring — unified monitoring and metrics module
• bt_api_risk — unified risk controls module
• bt_api_security — unified security controls and compliance module
