I build cloud-native AI & data platforms at Peblink / World Literacy Research Center, turning student audio and reading data into structured literacy insights with speech AI, Python, FastAPI, and AWS.

🔬 Research: First-author of SigmaCam, Exact Decision Boundary Extraction for DNNs with Smooth Nonlinearities (IEEE IJCNN 2025).
🤖 I work across: AI agents, RAG systems, voice AI, data engineering, applied ML, and intelligent workflow automation.
🌱 Currently leveling up: advanced GCP data engineering, production-grade agentic AI, and scalable MLOps.
💬 Ask me about: Python, FastAPI, AWS/Azure, RAG, LangChain, Whisper, voice AI, dashboards, and ML research.
⚡ Fun fact: I love sand painting and cooking, probably because I enjoy turning raw, messy pieces into something meaningful.

🧠 Featured Research

SigmaCam: Exact Decision Boundaries for Smooth DNNs PyTorch · Interpretability · IEEE IJCNN 2025

A theoretically exact, recursive algorithm that extracts decision boundaries for MLPs with smooth activations (Sigmoid, SiLU), where prior exact methods (SplineCam) can't go. Ships with a pip-installable package, 8 Colab demos, and training-time boundary animations.
