About me

I am a Blockchain and Full stack developer. When I work on a project, I strive for excellence and 100% client satisfaction. Having an idea is easy, but being able to turn that idea into a reality is the tougher challenge. You have the idea ready, as well as detailed spec and graphics and etc, but the final missing piece of your app is to bring all of these together with programming. That missing piece is my specialty. With your design requirements and idea, I write the code to combine it all into a fully functioning. Blockchain ✔ Ethereum DApps development - smart contract, web3, metamask integration ✔ DeFi development: forking Uniswap, Pancake Swap, Sushi Swap ✔ Build and Deploy a Solana Smart Contract ✔ DEX and Centralized Crypto Exchange ✔ Web/Mobile Wallet ✔ Custom dApps ✔ ICO, STO, Blockchain Copyrighting and Whitepapers Full Stack ✔️ React, React-Redux, React Router, Redux-Saga, Next.js… ✔️Vue, Vuex, Boostrap Vue.. ✔️Django,Laravel,Node js
