I worked with big (1TB+) MYSQL installations and used Postgres and MSSQL databases in production with Ruby, Go and PHP. I know pure SQL and I'm able to create SQL queries that extract valuable information from databases. I also used Redis, RabbitMQ, Sphinx, ElasicSearch, and Cassandra in production on different projects.
I successfully worked remotely for 7+ years using both freelance and team model at different times in my career. I also organized distributed teams and were a team lead for them. I also participated in non-distributed teams. I widely use Scrum management framework and took part as a developer, as scrum a master and a product owner.Describe the most impressive thing you've done.
