Hey, bellabob, welcome to the forum!

I suppose you want to say "I'm Bradly and I speak Russian".
Я Брэдли и я говорю по-русски

Notes: Spelling of foreign names can vary, but in most names "э" or "e" are used in place of English "a". "Или" means "or", "и" means "and".
"Говорить" is an infinitive form (=to speak), but in this sentence you need 1-st person singular, Present Tense ("говорю").
"Русский" is an adjective ("русский город - "a Russian city"), "по-русски" is an adverb that means roughly "the Russian way" and is commonly used in phrases like "to speak/read/write Russian".
