Job description:
Friends, we are looking for Middle/Senior Fullstack web3 developer on our projects.
About the project:
The project is a frameworkdesigner constructormodular library for building Web3 applications. Its main goal is to increase and speed up the adaptation of Web3 in the masses, and to give a simple and universal tool for creating Web3 applications to both developers ("low code mode") and non-technical specialists ("no code mode"). A good analogy for a Casimir-Web3 ligament may be a Wordpress-Web2 link. You can read more about the product here https ://casimir.deip.world/

- Be comfortable with the modern stack and common standarts in Web3 (web3.js, ERC-20, ERC-721, near-api-js, NEP-141, NEP-171, client-side private key management, etc.);
- Writing extensive comments, documentation, design flow diagrams, and review PRs in English;
- Working with our team to create tutorials and demonstrations that allow other developers to easily use/interact with the open-source components you develop;
