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’m happy writing plain old Javascript or more likely using Express, Backbone, and most definitely and often; AngularJS. I also enjoy putting together compliant, clean, maintainable and responsive HTML5 and CSS3.
