Work Experience

Summers of Growth

From Academic Research to Industry Innovation

Over the past few years, I've gained valuable experience in both industry and academia. Currently, I'm interning at Nextdoor on the Notifications team, and in 2024 I worked as a Software Engineer Intern at Ford. Before that, I was a Research Assistant at Carnegie Mellon University's Institute for Strategy & Technology.

2025 SUMMER (CURRENT)

Software Engineer Intern: Nextdoor

At Nextdoor, I'm working on the Notifications team to enhance personalization and reliability for millions of daily users. My focus is backend development—optimizing delivery pipelines, building user-segmentation logic, and improving monitoring and observability in our services. Collaborating with engineers and product managers, I contribute to large-scale production code that helps to cultivate a kinder world.

Skills/tools I'm learning and honing:

  • A/B Testing & Experimentation
  • Data Analytics & Performance Metrics
  • Redis Caching Strategies
  • Message Queue Architectures
  • System Observability & Logging

2024 SUMMER

Software Engineer Intern: Ford Motor Company

At Ford, I embraced Test-Driven Development (TDD) and pair programming to craft a React-based tool for Call Center Agents, replacing an outdated system with a streamlined search experience. Tackling a tricky 30-second timer glitch in a Lean Coffee app was another highlight, where our collaborative approach ensured a flawless user experience. Mentoring new interns and guiding them through a thoughtful onboarding process was also a rewarding part of the summer.

Skills/tools I learned and developed:

  • React
  • Google Cloud Platform (GCP)
  • Tekton CI/CD
  • GitHub Actions
  • MongoDB
  • Jotai

2023 SUMMER

Research Assistant: CMU Institute for Strategy & Technology

As a Research Assistant to Professor John Chin at Carnegie Mellon's Institute for Strategy & Technology, I dove into the complex world of self-coups and revolutionary events. I cleaned and analyzed historical data, crafted detailed case studies in LaTeX, and contributed to the Historical Dictionary of Modern Self-Coups by creating bibliographic entries. Researching and writing about the Castro brothers' self-coups was a highlight, weaving their story into the broader tapestry of political upheaval.

Skills/tools I learned and developed:

  • LaTeX
  • Historical Research
  • Professional Writing

Projects

Cool Projects at Nextdoor (more coming soon!)

As a 2025 summer intern on Nextdoor’s Notifications team, I work on backend features to personalize notifications for millions of users daily. I’m learning to optimize delivery pipelines, implement user-targeting logic, and ensure high availability and performance at scale. Collaborating with cross-functional teams, I write tests, improve monitoring, and contribute to production services that boost user engagement.

CX Agent Portal

During my 2024 summer internship at Ford, I redesigned the agent portal for the company's customer service agents. The project involved creating an independent application with a user-friendly UI, incorporating feedback from agents to ensure an optimal experience. The solution was developed to operate without dependency on the existing content management system, which had a pending decommission date, ensuring long-term viability for Ford's customer service operations. Additionally, the application was hosted on Google Cloud Platform (GCP), and we implemented a CI/CD pipeline using Tekton to streamline development and deployment processes.

Jargon Garden

During a team hackathon at my Ford internship, our team created 'Jargon Gardon,' an app that humorously transforms phrases from the user into corporate buzzword gold. Built with React and TypeScript, and powered by Ford's LLM which we connected to through the in-house API, the project was as much about having fun as it was about developing our technical skills. Our playful approach paid off—we won the popular vote for best hackathon project, even though we were the only team made up entirely of interns.

RNN-LM with Self-Attention

To bolster my foundational knowledge of machine learning models and techniques, I built a recurrent neural network language model augmented with scaled dot-product self-attention. I implemented a custom RNNCell, attention mechanisms, and training loops in PyTorch to predict next-token probabilities on the TinyStories dataset. The model handles long-range dependencies by computing attention weights over all previous hidden states at each timestep. Due to CMU's academic integrity policies, the code is in a private repository. If you’d like access, please email me and I can invite you to view the repo.

Gotham City Tracker

As the main project in my 67-272: Application Design and Development, I developed 'Gotham City Department Tracker,' a full-stack CRUD application using Ruby on Rails, React, and MySQL. I led the entire design and development process, starting with creating user stories from a list of functional requirements. Following an incremental, agile approach, I built a custom API, implemented secure authentication, and designed a dynamic UI. The project leveraged MVC architecture for code organization, with MySQL handling database management.

Dynamic Memory Allocator

As a lower-level project, I implemented a custom 64-bit implicit free-list memory allocator with segregated free lists. The allocator maintains 16-byte alignment, coalesces free blocks, and uses size classes to minimize fragmentation and maximize throughput. Due to CMU’s academic integrity policies, the code is in a private repository. If you’d like access, please email me and I can invite you to view the repo.

Personal Website

For this website, I leveraged my experience with React, TypeScript, and Jotai from my internship at Ford to craft a dynamic Next.js web app. Using Framer Motion and GSAP, I created a captivating display that highlights my exploration of new frontend and design techniques. The result is a visually engaging and technically sophisticated site that reflects my growth and creativity in web development.
