# Leonardo Siu > Incoming @ Walmart Global Tech | AI/ML Fellow @ Break Through Tech | Full-Stack Developer @ UCI OIT | CS @ UCI Location: San Francisco Bay Area, United States Profile: https://flows.cv/leonardosiu Hey, I’m Leo, a third-year CS major at UCI (Intelligent Systems + Informatics minor) and an AI/ML Studio Fellow at Meta. I’m currently building end-to-end NLP pipelines and fine-tuning transformer models to surface demographic bias in large datasets. On campus, I ship software that serves people: • Full-Stack Developer @ Commit the Change, delivering features for nonprofit partners with React/Node/Postgres, and clean, testable code. • Software Lead @ CareTech, leading a team to build a food logging app powered by real-time object detection to align meals with the MIND diet and support Alzheimer's prevention. • Student Software Developer @ UCI OIT (SST), improving performance and reliability for student and advisor-facing tools at scale (.NET/C#, SQL Server). One of my favorite projects was leading a team to build RetiNova, an AI-powered web app that won Best Overall @ IrvineHacks 2025. We used computer vision to help make eye care more accessible. This is a project that really showed me how tech can make a difference. You can checkout out my projects and contributions on GitHub: https://github.com/baller7215 Outside of code, you’ll probably find me behind a camera, on the court, or just chatting about tech, projects, or anything interesting. Let’s connect if you want to talk about software, AI, photography, sports, or just swap stories! ## Work Experience ### Full Stack Developer @ Commit the Change, UCI Jan 2025 – Present Elder Law & Disability Rights Center Building a volunteer and donor management platform for the Elder Law & Disability Rights Center (ELDR), integrating Google Calendar, SendGrid, and Clio to streamline case matching, reminders, and volunteer hours tracking. ### Software Lead @ CareTech UCI Jan 2025 – Present Developing an AI-powered food logging app with real-time object detection to analyze meals and measure alignment with the MIND diet for Alzheimer's prevention. ### Backend + AI Systems Engineer @ Human Proximity Jan 2025 – Present BeesEye Architecting AI matching with OpenAI embeddings + Pinecone and a Redis cache, and shipping a React Native + FastAPI app with Firebase auth, storage, and proximity features. ### Software Developer (OIT SST) @ Office of Information Technology @ UC Irvine Jan 2025 – Present Helping build and ship advisor and student-facing apps at UCI OIT, where I turn student data into real progress. ---------- Develop and maintain core features for UCI Spark and ScoreShare, supporting thousands of users.
