I’m a results-driven Software Engineer & Machine Learning Engineer with 2+ years of production experience delivering full-stack development, distributed data engineering, and applied AI/ML systems.

At UCIPT, I partner with healthcare and research teams to build mobile monitoring and public-health analytics, including a React Native patient-monitoring app with secure GPS mobility capture, reliable sync, and authenticated serverless REST APIs for high-throughput ingestion.

I also build large-scale modeling pipelines over 2TB+ mobility data, turning noisy GPS traces into stays and behavioral features, then modeling outcomes with XGBoost and regression while adding NLP workflows with spaCy, NLTK, and transformer embeddings.

Beyond analytics, I architect RAG + fine-tuned TTS experiences that preserve privacy while improving responsiveness through streaming—alongside production ML APIs and monitoring from my retail recommendation and visual search engineering work.
