About

Senior Lead Engineer and Full-Stack Technical Lead with 10+ years of experience building scalable enterprise applications, modernizing legacy systems, and leading cross-functional engineering delivery.

I specialize in React, Node.js, TypeScript, API architecture, microservices, micro-frontends, system design, and AI agent development. My work focuses on turning complex operational problems into scalable technical solutions that improve performance, reduce manual effort, and create better user experiences.

Most recently, I have been building AI agents for wireless network troubleshooting and root-cause analysis, including an LLM-powered chatbot for natural-language interaction and Temporal-orchestrated workflows for recurring analysis and automated troubleshooting.
