Project Experience

E-Learning App

React Native, LLM, Express.js, MongoDB

I built a cross-platform learning app that generates fully personalized study courses based on a user's time availability and preferred depth of learning. The system uses GPT-4 to produce dynamic lessons, quizzes, and gamified tasks, removing more than 80% of the manual work normally required to create educational content. The backend, built with Express.js and MongoDB, supports real-time scheduling, progress tracking, and adaptive learning paths, maintaining 99.9% uptime during testing.

WhisperChain+

Python, Cryptography, TypeScript

WhisperChain+ is a secure, anonymous messaging platform designed for academic communities where privacy and accountability must coexist. I implemented hybrid encryption (AES-256 + RSA-2048), anonymous token issuance, and a strict role-based access model that separates senders, recipients, and moderators. The system preserves confidentiality while preventing misuse through built-in logging, moderation flags, and controlled de-anonymization mechanisms.

Pizzeria VR

Unity, C#, Maya

This VR game simulates a realistic pizza-making experience using the Meta XR Toolkit. I designed the full interaction system—from ingredient handling to oven physics—ensuring smooth, intuitive gameplay and a highly tactile user experience. The project emphasizes immersive simulation design, detailed 3D asset integration, and responsive feedback loops optimized for VR. It was showcased at multiple technology exhibitions.

Experience Highlights

Throughout my academic journey at Dartmouth, I've focused on building inclusive learning environments, advancing research in AI and sustainability, and empowering students to excel in STEM.

Teaching Assistant & Learning Fellow

Dartmouth College, Hanover, NH
Sep 2024 – Nov 2024

I supported over 120 students in calculus and C programming, offering 11 hours of weekly guidance through problem-solving sessions, project help, and one-on-one support. I worked closely with faculty to evaluate student work and provide detailed, actionable feedback, which contributed to a 33% improvement in overall course outcomes. Throughout the term, I focused on building an inclusive learning environment—helping students strengthen their mathematical intuition, develop confidence in programming, and approach complex concepts with curiosity and resilience.

STEM Academic Fellow

First Year Student Enrichment Program
Aug 2024 – Sep 2024

During this program, I created accessible and engaging lesson materials for Python and Engineering Mathematics, tailored for 90 incoming first-generation students. I led weekly study sessions designed to ease the transition into STEM coursework and build foundational confidence. Every participant reported positive feedback, highlighting the clarity of the materials and the supportive learning atmosphere. My goal was to make the first exposure to college-level STEM both empowering and enjoyable.

Researcher, Thayer School of Engineering

LISP, Hanover, NH
May 2024 – Sep 2024

I received a $6,000 research grant to design a graph-neural-network–based approach that integrates phonetic information into language models for low-resource language processing. Working with a four-person research team, I coordinated literature reviews across 23 papers, organized faculty meetings, and guided the project through bi-weekly milestones. Through iterative model refinement, we expanded the algorithm's applicability and improved performance across multiple underrepresented languages—moving toward more inclusive and equitable AI systems.
