Summary

Rockstar🎓
Top SchoolJosé Duarte is a Senior Backend Engineer with 10 years of experience building distributed systems, data platforms, and high-performance backends from prototype to production. Currently at CoW DAO after leading the Polka Storage team at Eiger, he blends low-level performance sensibilities (Rust enthusiast) with pragmatic Python data engineering—contributions include backend work on the widely used Prefect orchestration framework and frontend enhancements to the foam VSCode knowledge-tool. He's shipped storage abstractions, CI migrations, and data pipelines that reduce wasted computation, and has hands-on startup CTO experience building full-stack prototypes, mobile PoCs and scraping pipelines. A practiced mentor since college, he pairs deep technical curiosity in programming languages and systems with a knack for simplifying complex file and pipeline operations for others.
