I build data-driven software systems from ingestion and backend architecture through machine learning, APIs, databases, and deployment. My work spans data engineering, applied AI, full-stack development, autonomous systems, and edge computing, with a focus on building systems that are reproducible, testable, and usable beyond a notebook.
- 🔭 Recent work spans deep-learning time-series, a full-stack ML fault-detection app, an autonomous JetBot robot, a team time-tracking SaaS app, and a production-hardened auth template.
- 🧰 Comfortable across the stack - Python (TensorFlow / PyTorch / scikit-learn) and TypeScript (Next.js / Node.js / FastAPI / PostgreSQL).
- 🎓 IEECS - National Taipei University of Technology (NTUT).
