Experience

Software Engineer Intern

Amazon

- Alexa Deep Learning Core Team: developing low-latency and memory-optimized inference engines in C++ for both in-cloud and on-device Alexa Speech models, leveraging both generic and specialized chips

- Successfully integrated AWS Neuron Runtime library into Alexa's inference engine, enabling deep learning inference on AWS Inferentia hardware and resulting in a 4x cost reduction compared to NVIDIA CUDA with equivalent latency

- Utilized multithreading on Inferentia hardware to increase throughput by 2x

May 2023 - August 2023

Software Engineer Intern

Datadog

- Optimized DDSQL, a language modeled after SQL, to comprehensively query over Datadog's logs, metrics, and APM services

- Implemented RBAC (Role-Based Access Control) for a subset of queries, improving overall security for customer data

- Conducted extensive query shadowing for millions of DDSQL queries, resulting in a 50% improvement in query language support

- Successfully optimized query performance for time-intensive queries by 4x

Academic Intern

UC Berkeley College of Engineering

- Assisted 50+ students in weekly lab and discussion sections for CS61C (Computer Architecture) by teaching concepts of C, virtual memory, and caching

- Aided students in office hours with any questions about homework or projects

June 2022 - August 2022

Projects

Moodify

Spotify Mood Classifier

- Conducted exploratory data analysis on a large dataset of 50,000 songs from the Spotify Web API to extract unique characteristics using Python and data analysis libraries

- Developed and optimized a machine learning model using the k-nearest neighbors algorithm to accurately categorize the emotion of a particular song in a user's listening history

- Implemented an interactive classification feature that provided users with a detailed breakdown of their overall mood

May 2021

Simple Git

File Version Control System

- Implemented a version-control system, similar to Git, that featured 13 commands such as add, commit, merge, init, checkout, and branch

- Designed multiple classes to represent the internal structures during execution and a parallel representation as files to ensure the persistence of the program

April 2021

Scheme

REPL Interpreter

- Developed a fully functional Scheme interpreter using Python, which can loop, read, evaluate, and print

- Processed parentheses from Scheme syntax using recursion to evaluate and print functions
