Mostly building things on-chain

I'm Emmanuel — Signor on the internet. Lagos-based, writing software programs since 2020. Most of my time has been on EVM (Solidity), Starknet (Cairo), and Sui (Move), with recent Rust stints on Soroban (Stellar) and Stylus (Arbitrum). On a typical week I'm switching between a contract editor, a Next.js app, and a PR review.

A lot of my open source comes out of friction I hit while building. suiclient-error-decoder started as a frustrated afternoon during the Sui Overflow hackathon — Move errors were unreadable, so I shipped a small library that turns them into something a human can actually debug. It's on npm now. Most of the upstream PRs you'll see on the home page came out of the same impulse: hit something annoying, fix it, open a PR.

Teaching is a long thread. Before I went all-in on Web3, I spent over two years at Kodex Africa in Lagos as Product Development Lead — leading a small dev team and running the frontend curriculum at the same time. 70+ students through HTML, CSS, JavaScript, and React. A handful are at tech firms now, a few started their own companies, and others are teaching at hubs of their own.

That experience carried over once I moved into Web3. I've designed and run smart-contract curricula at DLT Africa and Web3Bridge, mostly for engineers crossing into the space from Web2 themselves. Teaching keeps me honest — you can't hand-wave through a topic when twenty people are about to write code based on what you just said.
