Can I upgrade RAM on 2015 Macbook Pro 13" Retina Display

I have an early 2015 Macbook Pro 13" Retina display, 3.1 GHZ Intel Core i7 processor with a 1 TB solid-state drive, and at the time I purchased it with 8 GB RAM. I am a programmer and would like to upgrade to 16 GB RAM, but I know that the RAM is soldered to the circuit board. I have some experience with unsoldering (solder-sucking) and soldering circuits, so I was wondering if this approach is feasible? Or if would I have to send my laptop into Apple? Or is it not possible AT ALL to upgrade the RAM.

Thank you!
