hello, i’m charlene!

I build thoughtful tech with heart.

I’m a mechatronics engineering student who loves intelligent systems, delightful products, and bringing big groups of people together.

chapter one · the craft

Where I’ve been learning & building

A mix of software, machine learning, mobile development, and the occasional thousand-person event.

Software Engineer, Applied AI

CodeRabbit · May 2026 — Present

Working on the applied AI behind CodeRabbit’s code reviews — making production LLM pipelines faster, cheaper, and measurably better before anything ships.

TypeScript · Python · LLM evals · GCP

Machine Learning Engineer

HubHead · Sep — Dec 2025

Made an AI extraction platform smarter and faster — refining how models read messy industrial data, and shipping the features that put results in front of users.

TypeScript · Python · Gemini · GCP

Software Engineer, AI & Mobile

RBC · Jan — Apr 2025

Brought LLMs into mobile banking — from RAG-powered security intelligence to on-device AI that turns raw financial data into insights people actually read.

Kotlin · Android · RAG · Gemini Nano

AI Research Intern

CATTLEytics · May — Aug 2024

Built a GenAI assistant that lets farmers talk to their data — blending document retrieval with natural-language-to-SQL over a live farm database.

LangChain · RAG · Text-to-SQL · PostgreSQL

chapter two · the heart

Engineer brain, people-person energy.

The through-line in my work is turning complicated things into experiences that feel clear, useful, and human.

At the University of Waterloo, I’m studying Mechatronics Engineering and making room for the things I care about outside the classroom: inclusive engineering communities, ambitious events, and projects that make someone’s day a little easier.
