I am a Lead/Staff Backend Engineer with 15+ years of experience. I specialize in reducing cloud costs, scaling large databases, and debugging systems at the syscall level.
Highlights:
* Saved $500k/year at Automattic: reduced S3 storage costs by 75% for a 2 PB dataset.
* 26x Performance Increase: Architected a bespoke binary protocol for WordPress restores, eliminating the #1 product churn reason.
* Scale: Managed a 30 TB+ PostgreSQL cluster (Citus) and NLP pipelines for MIT/Harvard for 10 years.
* Recent Build: Solo-founded https://aero.zip - a privacy-first file transfer service with E2E encryption and OPAQUE authentication.
I debug GnuPG with strace, migrate petabytes without downtime, and replace brittle Cron jobs with robust workflow systems. Looking for complex backend challenges.
Remote: Yes (12+ years remote experience)
Willing to relocate: No
Technologies: Python, TypeScript/JavaScript, AWS (S3/EC2 Cost Optimization), PostgreSQL (Citus/sharding), C/C++, Temporal.io, Rust.
