Is the speaker talking about me or themselves in this sentence?


> rilesさん日本語上手いのでもっと自信持っていいと思います 笑

I believe I've more or less gathered the translation, in that they think
(someone) should have more confidence because (someone) is good at Japanese,
but here's where I'm confused.

Who are they saying is good at Japanese, and who are they saying they believe
should have more confidence? I'm not sure how to tell.
