Bijan Pourriahi
Senior Full-Stack / Platform Engineer
Frontend · Backend · Data Systems · DevOps · Kubernetes · Automation · Rust · Python · Rails · TypeScript
I build complete software systems end-to-end: frontend applications, backend services, APIs, databases, infrastructure, deployment workflows, monitoring, automation, and data pipelines.
My strongest work is in complex, data-heavy products where the system needs to be reliable, inspectable, performant, and operationally useful. I work across product interfaces, backend architecture, data modeling, infrastructure, DevOps, system administration, performance optimization, monitoring, and internal tooling.
I have built SaaS products, market research platforms, trading infrastructure, research systems, dashboards, data pipelines, automation tools, browser extensions, CLIs, and backend platforms.
Previously built automated trading infrastructure for a hedge fund, including large-scale strategy backtesting, analytics, automated strategy selection, dashboards, and cloud operations. Current work includes QuantBox: a Rust/Python systems platform for research infrastructure, simulation, market-data ingestion, runtime systems, and automation.
Trading Platform Work
I built an internal futures trading workstation for managing multiple funded-style accounts from one operator surface. The system combined execution, copy trading, risk controls, account fan-out, strategy dispatch, live state monitoring, and research workflows.
Key capabilities:
- Managed 10 accounts simultaneously from a single execution and monitoring UI
- Copy-traded orders across account groups with per-account position, balance, drawdown, and guardrail visibility
- Ran hundreds of strategy variants across live and replay workflows
- Backtested thousands of strategy/day/configuration combinations with sortable strategy comparison views
- Supported real-time backtesting, live dispatch review, account health checks, kill switches, flatten/cancel controls, and operator explanations for each action
