Yuval in a few words
I build top-quality Back-End, Front-End and Full-Stack projects of all sizes. Depending on your needs, I can offer services either as an independent developer, or team-up with one of the internationally renown designers I work with to both professionally design and develop your project. I work with companies and individuals of all levels of understanding of technology, from complete unfamiliarity to absolute mastery. I mostly use the MERN Stack + TypeScript and Redux to build and deploy web scrapers, back-ends, and web/desktop applications. I also use some more highly specialized technologies when needed, like WebRTC and Socket.io.
Experience

Digital & IT
Freelance Solidity Developer - As a freelancer
• Providing end-to-end solutions for DApps, ERC-20s, ERC-777s, ERC-1155s, and more, including not only Smart Contract development, but also accompanying Full-Stack applications and integrating the two together.
• Writing scalable and reusable Smart Contract unit tests using Mocha + Chai to ensure no bugs are missed. Bugs cause way more damage with Smart Contracts than with normal Full-Stack apps.
• Using my previous experience in Cyber Security, putting a special emphasis on security where Smart Contracts are involved. In the Blockchain world, more than anywhere else, a company's reputation can very easily be destroyed by a security breach.
• Putting a special emphasis on efficiency to ensure any Smart Contract function used costs only the bare minimum required from the users.
