I have been called both. However, CodyChat is an actual business so I am mostly called a Developer. We have three tiers of developers on the platform. 

Tier 1 - Junior Developers (1-2 Years of experience)
Tier 2 -  Developer (3-6 Years of experience)
Tier 3 - Senior Developers (6+ years of experience)

I am currently under the Tier 2 title and I also do some database security work for them on the side.
