Hey 👋, I'm
Tejus Vijayakumar
I am into training deep neural nets on large datasets
As a multidisciplinary Engineer with over 4+ years of experience at a leading bank, I led a team of 6 engineers to develop and deploy machine learning solutions. I also developed more than 12 payload-encrypted APIs handling approximately 1 million daily requests. My hands-on experience includes developing deep learning models from scratch, such as a 60 million parameter Transformer Model trained on a single Nvidia A100 GPU with 40GB memory for code summary generation, fine-tuned LLMs, Deep Q-Network (DQN) for reinforcement learning, and Residual Network (ResNet) for image processing. Additionally, I have worked with image processing tools like OpenCV and stay updated on important recent advancements, including multimodal Large Language Models (LLMs).
Graduated MSc Artificial Intelligence & Machine Learning from the University of Limerick, Ireland.
