Web3 Developer - Solidity, Node.js, TypeScript

First of all, I think it's more fair for you to agree on price per each project milestone, rather than per hour. I'm open to whatever works better for you. I started coding in 1993 and worked in software development for most of my career: as a dev lead, a project manager and a founder. I managed development teams. I love the magic of crafting high quality software products, and scaling them to be used by millions of users. As a true professional and software craftsman, I focus on quality. Clean code, good architecture and test coverage are super important to me. I'm also a big supporter of software development processes that are based on values and principles of the agile manifesto, giving client as much value and flexibility as possible. While I'm comfortable with different technologies, I can provide the most value on projects which use Solidity with Hardhat and Ethers.js, TypeScript and Vue.js. To see my work, take a look at my portfolio website. It would be great to have a call to get to know each other and join forces to build a web3 product which your users are going to love.

Relentless on the details.

Hello, I’m a full stack web3 engineer, and I’ve worked on all aspects of a web3 product. At my last company I owned the engineering of the MVP web app (app.dimo.zone), and had a large role in the associated mobile app. I did most of the web3 integration into these products. I worked on the smart contracts for on-chain vehicle identity using ERC721, and the diamond pattern. We used meta-transactions to make the onboarding experience more smooth. The contracts were bridged to the Polygon L2 out of fee considerations. I was also on the hardware team. I was responsible for integrating the HSM to be compatible with Ethereum cryptographic operations. I am looking to get in on the ground floor of a web3 startup, and help refine the product over many iterations. Thanks, Hersh
