> Computer Engineering @ UWaterloo

Recently, I really like building small things that make my life easier :). Currently interning at Shopify on retail Point of Sale (POS) team.

about_me

I'm a 2nd year Computer Engineering student at University of Waterloo with a passion for building innovative solutions. I love working on game development, web technologies, and exploring new programming languages. Currently seeking opportunities to apply my skills in real-world projects and contribute to meaningful software development.

When I'm not coding, you can find me experimenting with game design, 3D modeling in Blender, or working on personal projects that challenge me to learn new technologies.

Software Engineer Intern

@ Shopify|Ruby, TypeScript, React Native

May 2026 - August 2026

>Scaled Shopify’s mobile POS for in-person merchants by optimizing offline-to-online sync, reducing 95th percentile sync latency by about 35% (1.7s to 1.1s) and supporting about 20k daily checkouts.
>Built reliability and telemetry improvements for POS sessions in React Native/TypeScript, cutting crash rate by about 22% and increasing successful checkout sessions to about 99.3%.

Software Engineering Intern

@ BrainRidge Consulting|TypeScript, Node.js, PostgreSQL, AWS, GitHub Actions

January 2026 - April 2026

>Designed and deployed a highly-scalable automated HTTP data ingestion pipeline (Node.js) for a RAG-based AI model, accelerating knowledge base expansion by 70% and eliminating 83% of manual administrative overhead.
>Spearheaded the development of a multi-query RAG-Fusion retrieval engine utilizing AWS Bedrock and advanced LLM prompt engineering, achieving an unprecedented 98% document recall for ambiguous user queries.
>Architected a hybrid search infrastructure combining BM25 and vector search with Reciprocal Rank Fusion within PostgreSQL, optimizing exact-match retrieval accuracy and plummeting zero-result rates by 62%.
>Pioneered a real-time, low-latency conversational AI voice system via WebSockets and AWS Nova, delivering sub-500ms median response times for natural banking interactions complete with voice barge-in capabilities.
>Transformed cloud infrastructure deployment by engineering a multi-environment CI/CD pipeline leveraging Terraform, GitHub Actions, and AWS, accelerating release velocity by 73% with rigorous production safety gates.

Software Developer Intern

@ Exo-Insights|Android Studio, Java/Kotlin

May 2025 - August 2025

>Engineered a robust Android SDK (Java/Kotlin) to ingest and process high-frequency (25Hz) gaze-tracking telemetry from smart glasses, with 99.9% data upload reliability via RESTful APIs across 30+ edge devices.
>Developed high-performance Android UI components for real-time biometric visualization (heart-rate and gaze tracking), optimizing internal QA testing lifecycles and reducing debugging overhead by 30%.
>Streamlined sensor-to-cloud data ingestion by integrating custom Bluetooth SDKs and REST APIs into the core pipeline, significantly accelerating data availability by cutting latency by 40%.
