Jisheng Yang

I build infrastructure for AI agents and quantitative systems.

My work is centered on one question:

How do we make autonomous systems reliable enough to operate in complex, high-stakes engineering environments?

I focus on modular system design, evaluation, monitoring, replay testing, and operational safety. My current projects involve AI agent workflows, quant research infrastructure, market data pipelines, and execution systems.

Areas of Work

AI Systems

  • Agent workflow design
  • Tool-use architecture
  • Evaluation and scoring frameworks
  • Instruction-following and compliance measurement
  • Human-in-the-loop control
  • Observability, auditability, and replay

Quant Infrastructure

  • Backtesting architecture
  • Market data pipelines
  • Orderbook analysis
  • Signal generation and execution diagnostics
  • Risk controls and system monitoring
  • PostgreSQL-based research data models

Engineering Foundations

  • Linux / WSL / remote development environments
  • Modular service design
  • CI, testing, logging, metrics, rollback, and reproducibility
  • Systems programming, numerical computing, and research tooling

Programming Languages

  • Rust
  • C / C++
  • OCaml
  • SystemVerilog
  • Python
  • Bash
  • R
  • C# / .NET
  • q / kdb+
  • Go
  • TypeScript

I speak...

  • Chinese
  • English
  • German

Personal Background

I study Condensed Matter Physics and Algebraic, Differential Topologuy at UC Berkeley.

I am also a classical musician and have professional experience in the German legal field.

Personal Interests

  • I love driving my old Jeep into untouched wilderness—deserts, forests, and coastlines—with my dog, a vintage large-format camera, and my diving gear (without my ThinkPad laptop)

  • I am currently building a hybrid wheeled quadruped robot, which I hope will be able to carry 100 kg of diving equipment for me across rocky reefs. I am also modifying my Choptima CCR and developing a high-performance diver propulsion vehicle.
