### Quant Developer & Systematic Options Trader
Production-grade•quant engineering
Quantitative infrastructure for systematic trading strategies. I build the tools that make edge repeatable: backtesting pipelines, strategy validation frameworks, and the type-driven code that holds them together.
25 years engineering software systems: from trading and risk platforms at Citadel, Bank of America, Morgan Stanley, and BNP Paribas, through building performance and analytics Software-as-a-Service (SaaS) products at Northern Trust, Salesforce, and Jive. Now I am back to quantative finance with algorithmic trading systems at Referential Labs, building strategy robustness validation, backtesting infrastructure, and portfolio risk analysis.
Quant Infrastructure
Backtesting pipelines, strategy validation frameworks, and data infrastructure built for correctness first.
- QuestDB time-series storage
- Robustness testing pipelines
- Statistical validation
Strategy Validation
Quantitative, statistical, and econometric methods for validating algorithmic trading strategies.
- Backtesting with zipline
- pandas / polars pipelines
- scipy statistical analysis
Type-Driven Engineering
Large codebases that survive contact with production. FP correctness applied to financial systems.
- Scala 3 / ZIO2 pipelines
- Haskell domain modeling
- Property-based testing
Distributed Systems
Trading and risk platforms, SaaS backends, and cloud-native infrastructure at scale.
- AWS / Kubernetes / NixOS
- High-availability systems
- SRE & observability
Backtesting & Validation Pipeline
Building infrastructure for validating algorithmic trading strategies using quantitative, statistical, and econometric methods. Robustness testing with QuestDB, Python, numpy, pandas, and zipline-reloaded.
Strategy Research
Applying quantitative methods to systematic strategy development. Using Pandas TA, scipy, polars, and quantdsl for signal generation and strategy validation.
Distributed Systems
25 years designing resilient distributed systems, from trading platforms at Citadel and Bank of America to SaaS backends at Northern Trust and Salesforce. Scala/ZIO, Haskell, and functional programming at scale.
