Senior fullstack developer (PHP,Node.js,React.js)

Hi, I’m a web/mobile developer and developed my first program 22 years ago when I was 10 :). Also, I’m a tech leader of outsourcing software company. With my team, I have developed more than 100 projects over the last 5 years. I’m good at formalizing business requirements into working solutions with clean commented code covered with tests. I have strong fundamental skills in the computer science field, country-level programming contests won and tons of real-life development experience. I aim to create products for people, and I do care about real use cases and UI. For example, I have developed “German Tinder,” educational social network for the University of North Carolina, an E-commerce platform for Canadian medicine provider and many other projects that are used by thousands of people. My expertise lies in both MEAN and LAMP stack development. I love API-first paradigm with React.js/Angular.js/Redux on the frontend, PHP/NodeJS for the backend for complex interface rich apps. Also, I’m ok creating classy PHP/SQL web apps that output HTML right from the backend. My focus for business development is to find the best tool for the job, either an existing service or one I build myself. The tool can be a small plain PHP script or large modular MVC app based on Laravel/Symfony. Whatever gets the job done! Today I’m willing to take a new feature-rich and exciting project. Besides me, I have more than 50 employees on my team, including PM’s to handle the development process smoothly. Especially I would love to work with BigData or projects requiring hard skills in math or biology. For example, I’ve developed a math engine for casino slot machines, a social network for animal breeders where genetics knowledge was in use or did a cryptocurrency stock exchange simulation app. So, how about a chat about your next project? ;-)
