Looking for code that’s copy-pasted by an amateur and is full of security vulnerabilities? Yeah, didn’t think so. You want an expert you trust to handle the most critical component of your project. Blockchain code is immutable (it can’t be changed). If you don’t get this part right, it will sink your entire project. That’s why I’m here to help. I’ve been involved in blockchain development since 2016, coding for over 10 years. I’m so passionate about this space that I constantly annoy friends and family because I never stop talking about it. Simply put, I’m an expert. So if you’re looking for someone to guide you through this world, give you fast and reliable deliveries (with full transparency), and make sense of all of the technical jargon for you, I’m your guy. Blockchain dev ✅Solidity ✅Rust ✅Smart Contract ✅NFT I love to develop the blockchain system because I think blockchain is a new and great idea to make the world more brilliant and efficient. That's very interesting and attractive to me. Front-End Web dev ✅React.js ✅Vue.js ✅Angular ✅Jquery I felt like everything just clicked when I started full-stack JS development. It's a perfect convenience for developers, and it's a perfect choice for clients who want brand new sites. I always like to start from scratch and finish perfectly in my hand. Back-End Web dev ✅Node ✅Elixir ✅Go ✅Ruby on Rails ✅Python ✅PHP ✅Laravel ✅CodeIgniter I have more than 5 years of backend development, using Node(ExpressJS) and other backend program languages. Database Management ✅MySQL ✅MongoDB ✅GraphQL ✅PostgreSQL Hybrid Mobile dev ✅ionic ✅React Native React Native is a natural outcome as a React developer. Personally speaking, Ionic and Angular are better than React and React Native. I feel much more freedom when using Ionic5 because it provides almost all web features. 3 years of Android(Java) Native development experience was a big plus as a Hybrid developer. Cloud and Dev-Ops ✅AWS, ✅GCP, ✅Docker Beyond coding, the most important thing for us is the cloud. I have spent more than 40% of my time on AWS and GCP and it was a valuable experience. And also Docker, it’s efficient and has cross-platform convenience.
