Post trial and appeal practice is complicated so you need an experienced criminal attorney to represent you. There are specific timing issues so retain an attorney immediately. The notes of testimony from the trial are key along with a complete set of all the discovery material.
Not clear but assuming you are the defendant, is that correct. Following entry of a guilty pleas, a defendant's appeal rights are very limited. This area of practice is complex and definitely not favorable context for DIY efforts. You need to talk to an attorney familial with this specialized area of practice. Feel free to reach out for private conversation.
