I'm a professional Full-stack web/mobile developer with more than 9 years of hands-on experience in the field.

During this time I have successfully completed numerous projects working independently as well as working in the team. I gained valuable experience working on both: frontend and backend – that's including analytics and processing of large volumes of data.

My skill set consists of the following (Frontend/Backend):

ReactJS, React Native, VueJS, AngularJS, Angular 2/4, HTML5/CSS3

NodeJS, Express/Sequelize/Graphql/RestAPI

Solid experience and strong skills in DB design and management using such DBMS as MySQL, PostgreSQL, SQLite, MongoDB, CouchDB, writing complex SQL-queries with sub-queries, cursors, creating stored procedures, triggers, etc.

Plus I have extensive experience in DevOps. This includes cloud platforms as AWS, Heroku and Digital Ocean.

In-depth experience with S3 (upload, retrieve and delete files), SES (configuring development account), EC2 (and related like Route53, Load Balancer, etc.) 

I'm a hardworking and result-oriented individual contractor. I always try to get everything completed successfully within the deadlines. I stick to best practices of modern web development, however, I'm also familiar with time-honored solutions – that allows me to deliver the best results in short terms.
