No, you're not allowed to represent the corporation, which is a separate and legally distinct entity from yourself. Since the corporation is a legal person, but cannot represent itself (not being an natural person, it cannot operate pro se), it must be represented by an attorney. That, then, brings in regulations on who may act as attorney (which is not always synonymous with lawyer or barrister) in litigation in a given jurisdiction. If you wish to represent yourself, then you need to be personally party to the litigation, which is what the legal personhood of the corporation protects you from (to a degree).
