About 15 years in web development working primarily with Ruby, Ruby on Rails, and the full stack of related technologies, with strong knowledge of front-end development. During these years I had opportunities to work solely and in teams, as a senior developer, a tech lead, a team lead, and a software architect.I have experience in building regular websites, marketplaces, social networks, and complicated CRM systems as well as command-line applications, background services, web-crawlers, and more. Additionally, our team and I personally had a good experience in building hybrid mobile applications with Ionic, Angular, and React Native, which are now available in stores and have near 5-star rating.Additionally, I usually take full responsibility for DevOps, infrastructure management, deployments, security, backups, and overall reliability of the system. Good experience managing the infrastructure with instruments like Chef.
