Rockstar🎓
Top SchoolTomek Drwięga is a founder and veteran software engineer with 15 years of experience, now running Fluffy Labs from Wrocław and advising blockchain ventures like Empireum. He is a polyglot developer deeply experienced in Rust, JavaScript and Java, with a strong history at Parity Technologies contributing to core Substrate and Polkadot components. His open‑source work includes maintaining rust-web3 and improving ethabi, addressing build and compatibility challenges and implementing core JSON‑RPC and transaction-pool logic for widely used blockchain stacks. Tomek pairs low-level systems expertise (serialization, proof generation, U256 arithmetic) with practical product work—CLI tools, mobile UI for an air‑gapped signer, and developer-facing SDKs. He frequently bridges research-grade protocol work and production usability, for example adding RPCs, watchers and extrinsic handling to Polkadot nodes. Outside pure protocol code, he’s coached JavaScript workshops and built interactive learning apps, showing a commitment to developer education as well as engineering.
