  • Work with text-to-speech systems such as Google WaveNet, Amazon Polly, and Azure Neural TTS.
  • Create and optimize Chatbots using Rasa, Dialogflow, LangChain, HuggingFace Transformers, or LLM-based frameworks.
  • Implement entity extraction, intent classification, embeddings, and transformer-based models.
  • Perform data preprocessing, feature engineering, model training, optimization, and evaluation.
  • Integrate AI/ML models into production environments using REST APIs, Docker, and cloud services.
  • Analyze model performance and improve accuracy, latency, and response quality.
  • Collaborate with cross-functional teams to design conversational flows, voice UX, and call automation logic.

Required Skills and Qualifications

  • Bachelor’s or Master’s degree in Computer Science, Data Science, AI/ML, or a related field.
  • Strong proficiency in Python, Pandas, NumPy, Scikit-learn, TensorFlow, or PyTorch.
