•  University of Waterloo Waterloo, ON

Research Assistant May 2025 – April 2026

◦ Optimized deep learning models for audio reconstruction in reverberant environments, reducing the loss to 10−9

◦ Proposed a dual-path temporal-frequency model combining convolutional and attention modules for multi-point sound field control, achieving up to 10 dB noise reduction while maintaining spatial selectivity.

• eBay

Software Development Engineer Intern January 2024 – April 2024

◦ Developed a full-stack e-commerce web application, serving over a million users. Implemented 10+ functionalities allow sellers to manage multiple stores’ information, product listings, and order processing.

◦ Implemented the back-end architecture in Spring Boot with RESTful APIs utilize HTTP methods. Created reusable UI components using React.js. Achieved 95% test coverage using JUnit for APIs tests.

◦ Integrated PostgreSQL for data storage and optimized database performance through parallel processing and indexing techniques, achieving a 40% improvement in query response time.

• Huawei Technologies Canada Co., Ltd. Markham, ON

Software Development Engineer Intern May 2023 – December 2023

◦ Designed and implemented a network automation toolchain including Yang model compiler into structured configuration data, integrating gRPC-based microservices, Datastore management, and protocol support (NETCONF, RESTCONF) to automate device configuration generation and validation across network systems.

◦ Designed service using Protocol Buffers to serialize and deserialize data structures defined in Yang.

◦ Refactored data source loading procedures, reducing software testing runtime by 70%. Achieved 100% unit test coverage with Google Test and JUnit for both the C++ server and Java client.
