30+ years building production systems
I've built systems from scratch and inherited disasters
I analyze systems, not sell solutions
What makes analysis different:
- I look at what the system actually does, not what the docs say
- I identify incentive structures and second-order effects
- I document trade-offs, not prescribe "best practices"
Why 30 years matters:
I've seen the same architectural patterns succeed and fail across decades. Enterprise applications. Web applications. SaaS platforms. The technology changes but the failure modes don't.
I know where systems drift because I've watched it happen in slow motion. I can spot the gap between "what we built" and "what we actually need" because I've been on both sides of that gap.
