About Ian

Software engineer by training, I am passionate about the web and cryptocurrencies, but especially about their underlying technology: the blockchain. A weapon of mass (peaceful!) destruction that brings decentralization and has a real capacity to impact our society in almost all its aspects!
Whether you want to develop a complex web3 project or launch an NFT collection, I will be able to accompany you in your adventure, here are my main activities:

🖐🏼Development and deployment of smart contracts in Solidity, for EVM compatible blockchains (Ethereum, BSC, Polygon, Avalanche,...). Use of proxy patterns (upgradable smartcontracts), use of standards (NFTs: ERC721/ERC1155, fungible tokens: ERC-20,...)

🖐🏼Design and integration of decentralized applications (Dapps) with React, libraries such as Web3.js/Ethers.js or Moralis/TheGraph.

🖐🏼Development of services/workers to interact with blockchains (retrieve/filter data, store in external DB, execute transactions...) with JavaScript/TypeScript (NodeJS).

🖐🏼Design of scalable infrastructures for all your projects (make the best use of AWS resources and services) - deployment automation (thanks to tools like Terraform or Github Actions)

🌞My enthusiasm for the web and particularly web3, drives me to stay informed and test the latest technologies, frameworks, and libraries that I use in the projects I undertake. I am constantly looking for optimization and performance, but the most important aspect remains security.
