At Applied Materials, I lead development of an equipment monitoring and maintenance platform that turns real-time tool sensor data into preventive maintenance plans. I’ve built Angular dashboards and Python services for Etch, CMP, Ion Implant and other process tools.
I also designed and built a conversational AI assistant for site engineers using MCP, LangChain and LangGraph, and implemented a RAG knowledge base from support documents and release notes.
At HTC Global Services, I improved State Farm applications’ performance by about 70% and reduced database response times by 40% through refactoring, caching and query optimization. I also containerized and deployed applications on AWS and built Lambda functions to rotate RDS credentials stored in HashiCorp Vault.
Earlier at HTC Global Services, I developed Angular and Node.js applications, designed REST APIs, integrated Splunk and CouchDB, and contributed to the migration from AngularJS to Angular 2+.
