Hi, I'm Ronald Lee
I'm a Computer Science student focused on building reliable systems, intuitive interfaces, and maintainable code — spanning AI, software engineering, mobile development, networking, and cybersecurity. I like turning ambiguous problems into shipped, well-tested software, and I'm currently deep into large language models, applied ML, and offensive security.
Who I am
Introduction
I'm a Computer Science student focused on building reliable systems, intuitive interfaces, and maintainable code — spanning AI, software engineering, mobile development, networking, and cybersecurity. I like turning ambiguous problems into shipped, well-tested software, and I'm currently deep into large language models, applied ML, and offensive security.
Career goals
I want to work on systems where AI, security, and good engineering intersect — whether that's building safer LLM-powered products, hardening infrastructure, or shipping mobile experiences that people actually rely on. Long-term, I'm aiming for a role that lets me go deep on applied ML while staying hands-on with full-stack and security work.

Where I've been
Internships, hackathons, open source, and freelance work.
Software Engineering Intern
Company Name · Remote
Contributed to an internal tooling team, shipping features end-to-end across a TypeScript/Node.js backend and a React frontend.
- Shipped a feature that reduced manual triage time by an estimated 30%
- Wrote integration tests raising coverage on the touched module
- Paired with senior engineers on code review and design docs
University Hackathon — Finalist
Campus Hack Night
Built an AI-assisted study planner in 24 hours with a team of four, placing as a finalist among 40+ teams.
- Designed the RAG pipeline for syllabus-aware scheduling
- Presented the final demo to a panel of industry judges
Open Source Contributor
Various repositories
Occasional contributions to developer-tooling and security-focused open source projects — bug fixes, docs, and small features.
- Merged PRs fixing edge cases in CLI argument parsing
- Improved documentation for a static analysis tool
Freelance Developer
Self-employed
Built small web and mobile apps for local clients — landing pages, booking flows, and internal tools.
- Delivered 3 client projects on time and on budget
- Handled requirements gathering through deployment
Capstone Project — Network Intrusion Detection
University Coursework
Built a lightweight network intrusion detection prototype using traffic capture and a trained classifier to flag anomalous flows.
- Achieved strong precision/recall on a labeled traffic dataset
- Presented findings and a live demo to faculty reviewers
