About

I am a Computer Engineering major at McMaster University. I love problem-solving and have a passion for learning new skills. I am especially interested in C++, high performance computing, concurrency, operating systems, distributed systems, algorithms, and data structures.

I was previously a SWE Intern @ Pure Storage, where I profiled C++ code with Linux Perf to identify bottlenecks. I resolved these bottlenecks with many different optimization techniques such as branchless logic, template meta-programming, loop unrolling, and SIMD/vectorization. Over the course of my internship I was able to increase the throughput of a persistant metadata store by 5.07x (407%). I have also interned at MHI RJ Aviation as a Data Engineer Intern where I optimized ETL pipelines and created data visualizations with Python and Polars.

I am also active in extracurriculars on campus. I am the President of the McMaster Artificial Intelligence Society and a member of the McMaster Competitive Programming Club.

When I am not programming I enjoy working out, listening to music, and spending time with my friends.

Experience

Pure Storage

Software Engineer Intern

May 2025 - August 2025

Pure Storage
  • Worked with the FlashBlade Core Data team to optimize the decompression path of a persistent metadata store.
  • Profiled the hot path and identified bottlenecks with Linux Perf. Removed bottlenecks with classic HPC techniques such as compile-time calculations, loop unrolling, and vectorization which increased throughput by 407%.
  • Automated benchmark visualizations with Bash, Python, and matplotlib to save approximately 5 minutes per run.
  • Developed a robust unit and performance test generation system with C++20 template meta-programming and GoogleTest to validate the bit-level compression and decompression algorithms of the persistent metadata store

MHI RJ Aviation

Data Engineer Intern

May 2024 - April 2025

MHI RJ Aviation
  • Optimized 4 ETL Pipelines up to 82% by refactoring from Pandas to Polars and optimizing legacy Python code to Python 3.12 ensuring usage of Python optimization tools such as list comprehensions, generators, and decorators.
  • Developed 3 full-stack web apps in Python using Dash, Plotly, and Polars to dynamically display sales and backlog data from an SQL database which provided executives with a detailed oversight of $10M+ total monthly revenue

MacAI

President

May 2024 - Present

MHI RJ Aviation
  • Led new educational and project initiatives resulting in a record-high 1.3k+ member count.
  • Developed CNN and neural network demos in Jupyter Notebook using TensorFlow, Keras, sklearn, and matplotlib to further attendees understanding of concepts such as data preprocessing, model validation, and model fine-tuning.

Projects

Redis Server

Implemented two different server architectures - multi-threaded and lock-free event-driven. Compared them in both latency and throughput using Google Benchmark and std::chrono.

cpp Linux

Cache Profiler

C++20 and Linux cache profiling tool. Can estimate and visualize the size and latency of the L1, L2, and L3 caches.

cpp Linux Python

Market Order Book

A C++20 implementation of a financial exchange order book optimized for low latency and high throughput.

cpp Linux

3D Spatial Mapping Embedded System

A 3D spatial mapping embedded system made using a Time of Flight LiDAR sensor with the MSP432E401Y microcontroller. Full report on GitHub.
