SUMMARY
Backend developer with 3 years of commercial experience in PHP / Laravel. On both of my main commercial projects I am the only
developer responsible for the backend — from database schema and queue architecture to server setup and deployment on AWS.
In parallel, I have spent 4 years as the sole system administrator of a 500+ user network across 20 locations. This means I take a
feature from requirements to a running, monitored server without waiting for a separate DevOps engineer.
