Research Engineer

2021 - 2022

Lightning AI

Deployed a text-to-image generation model in production. Implemented a load balancer with dynamic batching to improve the model serving performance from 10 to 500 concurrent users. The app hit around 8,000 requests in two days without any failures.
Led the stable diffusion research with two team members, exploring the limits of the Lightning framework when a foundational model is deployed in production.
Collaborated with the Colossal AI team to integrate the Colossal AI engine that implements different parallelism algorithms that are especially interesting for developing SOTA transformer models.
Contributed to improving Tuner callbacks, fully-shared data parallel (FSDP) auto-wrappers, and DeepSpeed integration.
Worked on and maintained a Lightning open-source project built on top of PyTorch with currently 20,000 stars. When I joined it, I was already in the top 10 as a core contributor, and now I am in the top five.

Experience

PyTorch Lightning

https://github.com/Lightning-ai/lightning

A lightweight PyTorch wrapper for high-performance AI research. This framework empowers researchers to train their models efficiently at scale. It offers the flexibility to incorporate useful plugins during training and deployment, enhancing the overall functionality of the models.

Earwise

This application facilitates searching within audio and video files using either a question or keywords. Each query efficiently directs users to the precise moment in the file where the relevant information is discussed. This eliminates the need to watch or listen to the entire video, ensuring a time-saving and targeted user experience.

Rafiq AI

https://rafiq.ai/

Platform to create chatbots using your documents or website with multilingual functionality. This was part of a freelance project. Using the platform, one can create chatbots using their own documents/website and embed them on their website.

Munichat

https://munichat.netlify.app/t/moorestown

Implemented the whole AI and back end of a chatbot for US townships. This was part of a freelance project. Utilizing a chat interface, US citizens use the website to get updated information about their respective townships. The townships were created using the documents and website content of each respective township.
