Laravel (PHP), Flask (Python) or Rails (Ruby) along with MySQL, PostgreSQL and MongoDB. Running under Apache or Nginx. I am comfortable using these stacks for many projects; full CMS websites, database-driven web applications, REST-driven front end applications powered by PHP, Python or Ruby; or simple CRUD applications.
I maintain many servers for client projects and my own personal sites and applications. I therefore have experience with the setup, deployment, provisioning and day-to-day maintenance of full server stacks. This includes tools such as vagrant, chef & docker and platforms such as AWS, and Digital Ocean.
