About Yuval
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.
