Dear sir or madam,
I am an experienced Machine Learning Engineer. I have also done several projects in NLP, including speech recognition and machine translation, so I am familiar with seq2seq models needed for your project. I will develop a model in pytorch using the current state-of-the-art algorithm, which is BERT. I am sure that will produce the best results. I can guarantee quality and meeting the specified terms.
Yours sincerely,
Vlad
