Subhajit Chatterjee

I build AI stuff because AGI is cool (and hopefully they'll remember that when they take over). Usually I can be found training neural networks, debugging mysterious errors, and explaining to my family why I need another GPU. Sometimes I write about my adventures in deep learning, when my models aren't busy throwing cryptic error messages at me. At present getting my hands dirty with GPUs and parallel programming.

Timeline

Jul 2025

Oracle Netsuite

Upcoming Associate Software Engineer

Sep 2024

DatSol solutions

Developed a POC for zero-shot voice cloning, achieving 8x faster inference using vLLM optimization and A100-based parallel processing, with advanced acoustic and prosodic feature extraction for high-quality voice transformation.

June 2024 - Aug 2024

Project Intern (Generative AI) at Oracle

Developed a voice-based transaction system for purchase and sales orders, reducing inference latency by 7x and costs through distributed processing with smaller transformer models, while enhancing parsing accuracy and integrating APIs for seamless transaction handling.

Dec 2022 - Apr 2023

Informal Research

under Dr. Puspanjali Mohapatra on swarm algorithms and Neural networks. Implemented Extreme Learning Machine (ELM) with Salp Swarm Algorithm, achieving similar metrics to SGD-based models while reducing training time by 50%, significantly lowering compute costs.

2021 - 2025 (contd.)

IIIT Bhubaneswar

currently pursuing a Bachelors in CSE, with a GPA of 9.30/10.0
