    I'm a Software enthusiast having around 8 years of development experience in Javascript and PHP. I started my journey by creating web applications and then I got used to working with other platforms like mobile and desktop. I'm also contributing to open-source libraries. In fact, I'm part of a few out there. I have a strong base in software development with an outstanding record in my curricula. In the past few years, I went through many technical challenges with remarkable performance. I'm pretty stronger in quickly getting up and running with new technologies, completed around 50+ projects with development expertise. I have vast experience in working with version control systems, specifically BitBucket and Git, Deployment pipes, Jenkins, and Travis CI. So far, I worked with Laravel, express.js, feather.js, socket.io, Vue.js, React.js, and React Native Web as a web stack. On the other hand in mobile, I am using Native Android, IOS, Flutter and React Native to develop applications. I'm addicted to clean workflow using testing frameworks like Karma, Mocha, and Tape. I'm also a part of a team creating a cross-platform desktop application in Electron.js. I'm having sharp skills in database systems including MySQL, NoSQL databases, and Graph databases like OrientDB and Neo4j. I write clean and maintainable code, build a foundation of projects and keep my clients updated about emerging technologies. I believe in "Growing up every day and starting with a fresh mind to let others grow up".

    Hello! Greg's here. I'm a middle+ fullstack developer. Let me tell you a bit who and what am I. I'm in love with web development, especially a frontend part of it. I love to make things look and act cool when it comes to UI/UX. I'm not a web designer, but I definitely have some taste in it. Closer to the subject - what can I do for you? My speciality is full-stack development. In 2 words, I work with Node.js and React.js, which are (ofc with different node libraries) pretty enough to build anything you want in web. Either it's a simple landing, or a huge complicated application - nothing is impossible with these guys. Besides, I got a solid amount of experience with web3, built 2 NFT applications using pure web3, Metamask, and smart contracts on solidity (oh and of course React and Node) So, here's my tech stack: Frontend: • React.js (functional components, hooks, everything) - middle+ • SCSS (or pure CSS, works too) - senior • Typescript (please let it be ts, not js :P) - middle+ • Pure JavaScript (middle +) • Makes not much sense to mention, but still, HTML5 • MUI (material UI for React) • Metamask/web3 (crypto-wallet extension for blockchain interactions) Backend: • Node.js • Express • MongoDB • Web3 • Solidity • BrainTree • ActiveCampaign Common: • Git • Rollup • Webpack • Unix think that's it, probably there're more, but they're less important, this list should be descriptive enough I believe. And now, as a final, want to say a couple of words to make it easier for you to decide if you need me on your project(s) or not If you came here looking for a high-quality, clean, easily maintainable and extensible code solution - you came to the right place. The most important thing for me is to make things look, work, and act good. I don't write dirty code for faster speed reasons So, if you need a quick as-is prototype for super-rapid launch, I'm sorry, I'm not the best fit for you. Don't get me wrong. It doesn't mean that I work slowly or something. In fact, I work fast (based on my experience, it's usally way faster than average), I work efficient, I provide high-quality code. But what is important - I never sacrifice quality for time And in the end, want to say, that I love informal chatting. I'm fine with routine, like Agile or anything, but if I can talk to you directly with simple words, you know, just as is, it means a lot for me All the best, Greg P.S. My first name is Mikhail in fact, but it's gonna be more comfortable for you and me also to go for Greg instead (coming from my last name)

ReactJS Developer Hiring Guide

What is a ReactJS developer?

A ReactJS developer is a front-end specialist who builds scalable and interactive web applications using React, a powerful JavaScript library. They focus on crafting high-quality user interfaces (UI) and enhancing the overall user experience through efficient state management techniques like Redux. Their expertise also includes working with virtual DOM, reusable components, and tools like React Router for navigation in single-page applications.

These developers often collaborate with a development team to deliver projects like e-commerce platforms, mobile applications with React Native, and cross-platform solutions. With proficiency in JSX, CSS, HTML, and tools like Node.js, they contribute significantly to the success of any web development or software development project.

Why hire a ReactJS developer?

When you hire ReactJS developers, you bring on professionals who excel at building cost-effective and high-performing web apps. Their skills in creating component-based architecture allow for rapid development, debugging, and improved reusability of code.

ReactJS developers are ideal for startups, e-commerce businesses, and enterprises aiming to build real-time applications with seamless API integrations. They work with tools like Next.js for server-side rendering, GraphQL for data querying, and GitHub for version control. Additionally, their ability to follow Agile methodologies ensures streamlined workflows and completing projects on time.
