At NorthBridge Inc., I developed AI-enabled business applications that connect user workflows with machine learning services, retrieval systems, and production data. I built React and TypeScript interfaces for AI-assisted search and document analysis, alongside Python and FastAPI services for semantic search and model inference.
I implemented RAG workflows using LangChain and PostgreSQL/pgvector, including document chunking, metadata filtering, and source-grounded retrieval. I also built data preparation and evaluation pipelines with pandas, NumPy, and scikit-learn.
At Asterbyte Co., Ltd., I built data-intensive web applications and developed APIs connecting application data with classification, scoring, and recommendation services. Earlier, at Veltrix Digital Co., Ltd., I developed responsive interfaces, REST API integrations, and Python utilities for data analysis and reporting.
