AWS architecture, modernization, and delivery

I help teams modernize systems on AWS, make sound architecture decisions, and deliver working software.

AWS has been my main cloud platform since 2006, and it remains the foundation of most of the systems I help design and build. This site is where I write about architecture, modernization, delivery, and the practical decisions behind them.

Consulting

Shape the right AWS architecture

AWS-focused consulting for teams that need clear architecture, grounded tradeoffs, and decisions that still make sense once delivery starts.

Delivery

Bridge intent and execution

I work best where architecture has to survive contact with delivery, constraints, and real product pressure, not just look good on a diagram.

AI-assisted development

Use modern tooling with intent

I use tools like OpenCode, OpenAI Codex, and Claude Code to support research, prototyping, and implementation while keeping engineering judgment central.
