I build AI systems, edge computer-vision pipelines, and practical software products.
Currently, I’m developing Tutora, a private AI tutoring system evolving from multimodal RAG toward agentic tutoring workflows.
- AI systems: multimodal RAG, grounded generation, model evaluation, and local model deployment
- Edge and computer vision: Raspberry Pi, Hailo, YOLO, MQTT, and PostgreSQL
- Product development: Swift, SwiftUI, macOS, React, TypeScript, React Native, and Expo
- Tutora (private, in progress) — combines visual-document retrieval, evidence-grounded answers, citations, and evaluation.
- Jobwise — an open-source, privacy-first resume and cover-letter builder with local autosave, reusable templates, JSON backup/import, and print/PDF export.
- Multi-Camera Tracking & Data Fusion (ICP, private project) — a distributed edge-AI system for real-time multi-camera person tracking and cross-camera trajectory fusion, built with Raspberry Pi, Hailo, MQTT, and PostgreSQL.
- ParkMate (team project) — a vision-based parking occupancy system using YOLOv8, Raspberry Pi, AWS, MQTT, and Expo/React Native.
- FreshBrew — a native macOS menu bar utility for keeping Homebrew formulae and casks up to date.
