[01] BLOCKCHAIN DEVELOPMENT
Smart contracts and decentralised applications on Ethereum and EVM networks and on Solana — from contract code to the wallet flow a user actually touches.
Solidity · Rust · EVM · Solana · dApps
I build on-chain systems end to end: the contracts, the tests around them, and the application that users interact with through their own wallet.
On the EVM side that has meant token standards, presale-gated ERC-20s, marketplaces with auctions and on-chain approval workflows, across Ethereum and EVM-compatible chains such as BNB Smart Chain, Polygon, Shardeum and SKALE. On Solana it has meant Rust and Anchor programs, SPL tokens and NFTs, and a Solana Pay checkout for ecommerce stores.
