About Me

Hey! I'm Zhenyu, a software engineer with 10+ years of experience building high-performance infrastructure and trading systems at hedge funds and tech companies.

Background

I've spent my career at the intersection of distributed systems, cloud infrastructure, and quantitative finance. My experience spans:

  • Trading Infrastructure - Building serverless market data platforms processing terabytes of trading data daily
  • Portfolio Systems - Re-engineering portfolio optimization infrastructure for systematic trading strategies
  • Cloud Platforms - Designing self-service provisioning platforms and real-time auto-scaling systems

I'm passionate about designing systems that are fast, reliable, and elegant—whether that's low-latency trading infrastructure, distributed data pipelines, or concurrent systems that push the limits of performance.

What You'll Find Here

This blog is where I share what I'm learning and building:

  • Infrastructure & Systems Design - Patterns for building scalable, production-grade platforms
  • Concurrent & Parallel Programming - Deep dives into threading, async I/O, and performance optimization
  • Cloud & AWS - Real-world architectures, cost optimization, and operational best practices
  • Quantitative Systems - Trading infrastructure, market data processing, and backtesting frameworks
  • Problem-Solving Stories - Technical challenges I've tackled and lessons learned

Current Focus

Right now I'm exploring:

  • Low-latency systems and lock-free data structures
  • Building a concurrent quantitative trading platform in Python
  • Event-driven architectures for real-time data processing
