Building in the blockchain space since 2017, I have been contributing to multiple ecosystems (Ethereum, Polkadot) in multiple languages (TypeScript, Rust, Clojure). Lately I've been focusing on protocol development.

Some projects I worked on:

• lodestar Ethereum consensus client
• 🦀 substrate-playground and governance-ui polkadot tooling
• status.im a mobile Ethereum wallet/DApp browser
• extensions-fiddle a secure, decentralized and permissionless extension mechanism for mobile apps, using IPFS

Some other Open Source contributions:

• bitbox a NodeJS binary packager
• frames-prover a farcaster frames Ethereum funds prover
• 🦀 ipfs-pinner an IPFS pinner for Dot token holder
• estaminet a set of webComponents for Polkadot DApp development
• gist-preview and gist-serve web pages to visualize GitHub gists
• cljc-ethereum a Clojure(Script) isomorphic ethereum JSON-RPC client
• hipo a ClojureScript DOM templating library with node reconciliation, à la React
• happy a Clojure(Script) HTTP client
• semantic-versioning a semantic versioning helper library for Java, relying on bytecode manipulation
