Back-end Web Developer

Experienced in Javascript (ES5/ES6), Typescript, Front-end frameworks: Vue.js (Nuxt.js), Back-end frameworks: Node.js (Express.js), Databases: MySQL, MongoDB, NoSQL, FTS: Elasticsearch, HTML5, CSS3 (+ SVG, canvas, Web APIs), REST API, Git, Mercurial, Database Architecture for more than 12 years.
My specialization: developing the back-end for mobile applications, the back-end for simple and complex structured websites, the back-end for companies’ CRM-systems with many products, offices, and departments. I help my clients to design the data and solution architecture for their websites, mobile applications, and CRM-systems.
Even when I have a complete technical work task, I offer my clients how to optimize the work or improve something for further scaling. I worked both with startups and highly loaded companies' projects, that are well-known all over the world. My phone is always available, so I can help my clients if they have any trouble with the platform at any time. 
With the help of my professionalism and responsibility, the average working period with clients is about 1.5 years.  There are also some clients I’ve already been working for more than 5 years, and I think that we became almost one family during this time. That's why I am interested in a long-term partnership.
