I'm a MERN stack developer with experience of work in positions/roles of senior developer and system architect. Predominantly in my projects, I was using MongoDB, Javascript, Node.js Web API and ReactJS because with this stack it's relatively easy to get a good speed of development and high-quality result at the end. I also have work experience with MySQL, DynamoDB, Classic PHP, Laravel, CodeIgniter, jQuery, Knockout.js and many more. I like creating fancy user interfaces as well as optimizing server code increasing services productivity. I'm familiar with design patterns and I love to use it.
