Deep Learning Engineer
Voiceops
Developed the architecture and construction of AWS-based infrastructure for large-scale machine learning. VoiceOps is an AI-driven coaching and training platform for call centers. Built DL models to support the transcription process. Included scripts to pre-train, fine-tune, and fully integrate transformers (e.g., BERT, various Hugging Face transformers) into novel new architectures that included both text and statistical data. Built a modified transformer to automatically score the quality of transcriptions and determine whether they should pass to the client (ROC-AUC = 0.90). Created a modified transformer that automated the detection of speakers based on text (ROC-AUC = 0.97). Automated the estimation of how long a transcript would take to transcribe to replace a fixed-price system (cost savings of 20–30% of total transcription costs). Improved Automated Speech Recognition (ASR) via Seq2seq architectures
