Published Contributions

  1. Co-authored a research paper titled “Unveiling Emotions in Speech: A Multidimensional Transformer Approach”, exploring transformer-based models for detecting emotional patterns in speech. The work reflects a growing focus on applying deep learning to human-centered, real-time AI systems.
  2. Delivered a guest lecture on “MLOps: Productionizing ML Services” as part of the Assam Artificial Intelligence Initiative (AAII) Technical Lecture Series. The session covered best practices and open-source tools for deploying and scaling machine learning models in production environments.

Great systems aren't built all at once. They evolve through deliberate, incremental improvements that compound over time.
