Latest Experience
ML Intern at Rebellions
Summer 2024
Accomplishments:
  1. Successfully compiled and optimized a custom designed VITS model architecture on Amazon EC2 Inf2 instance, reducing inference time from 4260.83 ms to 90.46 ms, resulting in 46.1 times more throughput.
  2. Rigorously analyzed the Stable Diffusion XL Turbo model and presented the model architecture, training process, inference process, and benchmarks.
  3. Researched CNN and Transformer model architectures to improve my understanding, allowing me to better analyze and optimize larger DNNs.

During my internship at Rebellions, I thoroughly analyzed various machine learning frameworks and model architectures, benefiting from invaluable feedback and mentorship from seasoned industry practitioners. The internship enabled me to enhance my comprehension of AI acceleration in both hardware and software domains. I was able to make a positive impact on the company by conducting research, giving presentations, and implementing text-to-speech model architectures within specific compilation processes.
Software Developer at Cornell Digital Tech and Innovation
Spring 2024
Developer for CUApts, a Cornell Housing Website to help students find off-campus housing.
Accomplishments:
  • Agile Development, Version Control and Code Reviews: Led Agile development processes, completing weekly sprint tasks and reviewing pull requests, contributing to a 60% reduction in user bug reports.
  • Cross-Team Collaboration: Worked with designers to improve UI/UX by making elements more interactive with scroll and hover styling using React and TypeScript, decreasing the site’s bounce rate by 15%.
  • Improved Back-End Efficiency: Implemented and rewrote RESTful APIs using Express.js to retrieve apartment information more efficiently from Firebase Cloud Firestore, reducing API response time by 14%.
  • Improved User Retention: Implemented an email notification system, increasing user return rate by 45%.
My Pull Requests (Sprint Tasks):
  1. Add price and bedroom attributes to Firestore database script.
  2. Implemented new design, animations, and functionality for dropdown menus on the website.
  3. Sorting functionality for Apartments, allowing you to find apartments based on price, rating, number of reviews, and more.
  4. Designed and Implemented a Review Email System, notifying users when their reviews have been approved to thank users for their contributions to the platform. Designed the email's html and ensured compatibility across email platforms.
  5. Fixed UI inconsistencies across the website by communicating with the team's designers
  6. Revamped FAQ Page

Featured Projects
WaveOut
Barcodes are placed on nearly every product, but what if they aren’t needed? I explored the potential use of artificial intelligence to recognize supermarket items without the need for a barcode. I constructed WaveOut, an AI-powered self-checkout system designed to be both user-friendly and efficient. Simply wave your items at the camera and the AI will recognize it and add it to your cart. This can vastly improve the efficiency of self-checkouts and change the future of shopping.
Graph Algorithm Visualizer
A Python application to visualize graph algorithms including: Depth First Search, Breadth First Search, Dijkstra's Shortest Path Algorithm, Prim's Minimum Spanning Tree Algorithm, Kruskal's Minimum Spanning Tree Algorithm, and Ford Fulkerson Maximum Flow Algorithm.
Physics of a Fidget Spinner
In this project, I simulated the physics of a fidget spinner in VPython, including how the angle changes over time, the angular velocity, and the angular acceleration by combining my knowledge of rotational motion, simple harmonic motion, and the theorem of parallel axis
