About

I work across AWS data workflows, enterprise integrations and AI developer tooling. At FPT Software, I contribute to automotive retail interfaces and an AWS event-driven performance-data workflow. I use AgentBase-MCP to organize system knowledge and investigate bugs across components and event flows in the project's AWS event-driven system. As project AI Champion, I delivered three AI sharing sessions and support other teams in practical AI use. My personal projects focus on tools for coding agents. Earlier work includes team leadership, commerce, messaging and multi-tenant platforms.
