Transforming Data Into Actionable Insights With Machine Learning 

As a driven machine learning engineer, I focus on building models that learn, adapt, and solve meaningful problems. Explore my latest experience and projects, where I apply cutting-edge neural networks, LLMs, and AI deployment.

Hello, I'm Nathan! 

About me

Hi, I am a third year Data Science Student at the University of Waterloo. I have a strong passion for Machine Learning and I firmly believe in creating data-driven, scalable, and high impact AI Applications. I am always looking for challenging and innovative ways to solve problems using various Machine Learning techniques.

For me, using ML is not just about following the recent hype around AI. I believe these applications should be built around a specific product to derive maximum benefit for the user

Beyond Theory Lies Application! 

Image Captioning
Featured Project

Image Captioning

Developed an Image Captioning application using Pytorch. Build and Trained an Vision Transformer model as encoder and a modified Transformer model as decoder. The model was able to generate descriptive captions for images with a bleu score of 60%

Transformer
Project

Transformer

Build and Trained a vanilla transformer model from scratch capable of translating English to French using Pytorch.

Text To Speech
Project

Text To Speech

Built a Text To Speech application using Pytorch. I implemented the Tacotron 2 model using pytorch. The application was able to convert text into speech with a natural-sounding voice.

Image Search Engine
Featured Project

Image Search Engine

Implemented a CNN-based image retrieval system by learning semantic image embeddings and using Approximate Nearest Neighbors (ANN) for efficient similarity search; implemented automated CI/CD deployment using GitHub Actions and Docker.
