I primarily use PHP, but picking a new framework or language isn't a problem. I have extensive programming experience and I'm comfortable developing on the front-end or back-end as well as setting up or managing infrastructure.
I love Laravel and its associated stack: MySQL, Lumen, & Nginx. I am comfortable using Laravel for all sorts of projects: full CMS websites, database-driven web applications, REST-driven frontend applications powered by simple Laravel CRUD, SaaS application with integrated multi-database, multi-tenancy infrastructure.
