I currently work as a Principal Cloud Application Architect at Amazon Web Services (AWS).
I built this site to share knowledge about things I enjoy and to reinforce what I learn.
What I am reading
I read a lot. Books are my preferred way to learn something new.
Agentic Mesh: The GenAI-Powered Autonomous Agent Ecosystem
Eric Broda, Davis Broda
With the rise of autonomous agents, the question is no longer "How do we build agents?" but rather, "How do we manage an entire ecosystem of them?" The book explores interconnected agents that collaborate, transact, and fulfill tasks autonomously through an agentic mesh architecture.
Open Source Projects
I try to contribute to the open source community whenever possible.
Build Like Amazon Agent Skills
An open source library of skills, commands, and agent personas that guides AI coding agents through engineering workflows inspired by how Amazon builds, operates, and evolves distributed services.
The project organizes 27 skills and 10 bar raiser personas across working backwards, design, build, review, deployment, operations, and learning from incidents.
