## Work Experience
### Software Engineer Intern @ Ribbon
Jan 2024 – Jan 2025 | San Francisco Bay Area
- Designed and developed a microservice using FastAPI for document verification, employing a dual OCR strategy with Pytesseract and Claude 3.5 Sonnet Vision via AWS Bedrock, ensuring secure processing of critical financial data. Enhanced OCR accuracy by 20% through fine-tuning the YOLO architecture on a curated handwriting legibility dataset, utilizing advanced data augmentation techniques. Implemented custom confidence calibration for OCR outputs, improving reliability in extracting essential legal and financial data.
- Integrated the Power of Attorney Document Verification and Information Extraction microservice into the frontend using TypeScript, enabling seamless file upload and result retrieval with responsive UI. 
- Designed user flows for the Inheritance Widget, handling deceased member mismatches, missing beneficiaries, and probate processes with smooth screen transitions and Figma-based UI. Added educational content for inheritance status checks and contextual "Need Help" links for document uploads, enhancing user support.

### Software Engineer Intern @ Climformatics Inc.
Jan 2024 – Jan 2024 | San Francisco Bay Area
- Designed and developed the Climformatics website using Figma and React, creating pages like the landing page, solutions page, and media page with smooth animations (e.g., hover and scroll effects).
- Collaborated with the ML lead to develop an LSTM-based model predicting hospitalizations from heat stress, leveraging NASA POWER API and Google Drive API for time-series climate data with over 90% accuracy. Integrated the model with the website, building infrastructure for interactive GeoJSON visualizations of heat and hospitalization data. Utilized a locally hosted server with Google Cloud APIs for data queries.
- Co-authored and published a paper at AGU24 on modeling climate change impacts on heat waves and hospitalizations in California, focusing on fire weather prediction and risk management.

### Senior Game Theory Researcher @ UC Berkeley Electrical Engineering & Computer Sciences (EECS)
Jan 2022 – Jan 2023 | Berkeley, California, United States
Position: Senior "Veteran" Researcher
- Solved Slide-5 (currently the largest game in our system) using the Retrograde solver by splitting the game into tiers. Also designed and implemented the GUI for Slide-5.
- Tiers solved: 329,462
- Tier positions solved: 77,834,825,526
- Designed and implemented the GUI for Achi

Utilized Visual Value History to keep track of game trees. Applied various methods of Computational Game Theory to strongly solve abstract strategy games like chess/connect 4. Worked on creating/improving the GUI’s (Graphical User Interface) for several games on the Gamescrafters UC Berkeley website

### Academic intern CS61A (Structure and Interpretation of Computer Programs) @ UC Berkeley Electrical Engineering & Computer Sciences (EECS)
Jan 2023 – Jan 2023 | Berkeley, California, United States
Taught a section of 30+ students on CS61A: Structure and Interpretation of Computer Programs. Provided hands-on guidance in the lab using Python, SQL, and Scheme. Focused on critical programming principles like data abstraction and object-oriented programming, fostering independent problem-solving skills through mentorship and lab support.

Content: Higher-Order Functions, Recursion, Data Abstraction, Trees, Linked Lists, Object-Oriented Programming, Efficiency.

### Software Engineer Intern @ Dhillon Accounting CPA
Jan 2023 – Jan 2023
Designed and built a React.js website to showcase the firm’s services, including an About Us section, Calendly-integrated online scheduling, and a contact form for client inquiries. Implemented seamless hover and scroll animations to enhance user experience.
