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

About me

My name is Luqman, and I am a computer science graduate with Gold Medal. As soon as I finished my degree, I started earning certifications in trending technologies. One might say that I am mostly experienced in industrial implementation of software solutions, but that is just not it. I am also an active researcher in computer science, with specific interest in Blockchain and Distributed Computing. My key expertise include (but will never be limited to): - Developing full stack Blockchain Solutions: Including the core network setup, architecture design, business logic implementation, all the way up to front end and application designs. - Developing full stack Mobile and Web Applications: I have experience in trending stacks such as MERN, but will never stop my learning here. I am updating myself with other stacks and if work comes in, I think you can count on my skills.
