Hey, I'm Timothy! 👋
Statistics & Computer Science Student · AI/ML Enthusiast
I'm a Statistics and Computer Science student at the University of Illinois Urbana-Champaign, passionate about AI-driven applications. In my free time, I enjoy competitive programming and playing badminton. Check out some of the stuff I do below!
Work Experience
Coverbase Internship
Software Engineer Intern May 2025—August 2025
- Integrated Retrieval Augmented Generation (RAG) with Amazon Knowledge Base to create a vendor factsheet feature with modularized Tavily API + LLM queries, improving information retrieval speed by ~75%, deployed to all Coverbase customers
- Refactored multi-LLM Amazon Bedrock pipeline, resulting in faster execution and improved instruction-following by ~60% while reducing the API calls needed by ~50%
Technology Student Association 
Software Developer December 2024—June 2025
- Top 12 of 100 teams at the National Technology Student Association Conference
- Created an end-to-end full-stack Flutter application with a Flask API backend to assist sustainable eating with real-time analysis through a custom locally hosted prompt-tuned Vision Language Model (LLaVA 13B)
- Developed a RAG pipeline with vector embeddings, reducing LLM hallucinations by ~90% and improving reliability
University of California, Santa Cruz Summer Internship Program (SIP) 
Software Development Lead June 2024—August 2024
- Led software development for a 4-person team, building an end-to-end elderly fall detection system with Python, Android Studio, and Raspberry Pi for real-time video/audio streaming and processing.
- Enhanced fall detection accuracy by ~20% by integrating vision language models (Video-LLaVA, PaliGemma) with AlphaPose.
- Coordinated team efforts across hardware setup, ML integration, and Android app development; owned streaming pipeline + ML logic + notification system.
EduBeyond Internship
Web Developer Intern June 2023—Dec 2023
- Developed proficiency in web development using ReactJS, TailwindCSS, and MaterialUI

Research
Dual-Model Distillation for Efficient Action Classification with Hybrid Edge-Cloud Solution (NeurIPS Workshop on VLMs 2024) 
- Created an optimized action-classification model through a hybrid edge-cloud solution by training a Multi-Layer Perceptron to route queries between various open-source Video-Language Models (ViLT, LLaVA)
Enhancing the Binary Classification of Wildfire Smoke Through Vision-Language Models (AIxSET IEEE 2024) 
- Applied NLP innovations through Vision Language Models to camera imagery to enable early detection of wildfire smoke
Optimizing Large Language Models for Dynamic Constraints Through Human-in-the-Loop Discriminators (JMM 2025) 
- Used Large Language Models, human-in-the-loop, and automatic prompt-tuning to create smart agents for travel planning
