Staff Software Engineer and Distributed Systems Architect with 20+ years of experience. Author of "Hadoop with Python" (O’Reilly Media).
I specialize in scaling mission-critical data platforms and high-availability backend systems. Recent highlights:
- Architected a cloud-native agentic AI platform using Gemini 2.5 and custom MCP servers (sub-5s latency).
- Built a 15TB+ biomedical graph platform on AWS, reducing infra costs from $100k to <$10k/month.
- Engineered a 60TB NoSQL clinical discovery platform with 1-second p99 query latency.
- Scaled engineering organizations from founding hire to 20+ developers and $4M+ ARR.
Seeking Staff/Principal Engineering, Engineering Management, or Principal Architect roles. I thrive in high-growth environments where technical strategy meets deep execution.
