Summary
👤
Senior🎓
Top SchoolKonrad Sosnowski is a Defi Rust Engineer with 11 years of hands-on experience building high-performance trading, DeFi, and data systems across blockchain and finance. He specializes in Rust and Solana smart contracts, having delivered liquidity pool trackers, DEX contracts, and integration of exotic venues like Zeta Markets into execution engines, alongside EVM strategy-driven trading bots. His background spans full-stack and backend systems—from Go/AWS microservices for token distribution at Immutable to PySpark and Scala ETL for major banks—bringing production-hardened reliability and automation to every project. A fan of readable, simple design, he pairs judicious library research with pragmatic engineering, often tweaking codebases at odd hours to squeeze out performance and robustness. Based in Australia, he blends deep financial systems experience with modern Web3 tooling and a knack for turning experimental learnings into practical, non-traditional deployments.
