Hey 👋, I'm

Tejus Vijayakumar

I am into training deep neural nets on large datasets

A multidisciplinary engineer with over 3 years of experience at the largest bank in India, developed more than 15 payload-encrypted APIs, handling around 1 million requests daily. I also have hands-on experience in developing deep learning models from scratch, including a 60 million parameter Transformer Model trained on a single Nvidia A100 GPU with 40GB memory for code summary generation, DQN for reinforcement learning and ResNet for image processing. Additionally, I have worked with LLMs like LLAMA-2 and Mistral AI by quantizing weights and using Parameter Efficient Fine-tuning methods.

Graduated MSc Artificial Intelligence & Machine Learning from University of Limerick, Ireland.
