Experience

  1. Incoming Software Engineer Intern · OnePay

    Jun 2026 – Aug 2026
    • Joining the Walmart-backed fintech startup as a Software Engineer Intern.

  2. Software Development Engineer Intern · Amazon

    Jun 2025 – Sep 2025
    • Built an AI-powered chatbot leveraging retrieval-augmented generation (RAG) to translate natural language into SQL queries, execute them against a database, and return carbon footprint analysis.
    • Trained and fine-tuned an LLM using reinforcement learning with prompt engineering and validation through Amazon Bedrock's orchestration prompting, achieving 80% accuracy.
    • Designed a context-preservation function via a secondary agent that injected context rules from prior query history into the orchestration pipeline, reducing hallucinations and improving query reliability.
    • Developed a serverless architecture using Amazon CDK, Bedrock for NLP, Lambda for query execution, Athena and Glue for database access, and a React frontend with RESTful APIs.
    • Reduced time-to-insight by 75% and saved managers 15+ hours weekly by eliminating manual SQL queries.

  3. Firmware Validation Engineer Intern · Western Digital

    Jun 2024 – Jun 2025
    • Developed 15 automated tests in Python for firmware features using reusable test scripts and debugging frameworks, increasing log-page test coverage by 40%.
    • Analyzed and debugged firmware code in C++, discovering and fixing 5 critical bugs and improving log-feature reliability by 25%.

  4. Software Developer · Remote Sensing Research Team

    Dec 2023 – Jun 2024
    • Integrated four open-source web services into a single unified platform and built an interactive front-end dashboard in React, giving the research team one place to visualize, explore, and work with the combined data.
    • Containerized the backend services with Docker and orchestrated their deployment on a Kubernetes cluster, standardizing and automating the release process to cut deployment time by 40%.

Peter Eater

Jan 2025

A full-stack web app built during a UCI hackathon that lets students rate and review their campus cafeteria's offerings so their peers can make more informed dining decisions. I built an API gateway in Flask backed by MongoDB and a set of REST APIs that keep menu data accurate and continuously updated, surfacing live student ratings and reviews directly in the interface.
