Technical leadership with a business edge.
Software architecture for products that need to move fast.
How I help
My recommendations come from over two decades of building systems and living with the consequences of those decisions. Technical and commercial considerations shape each other from the start.
Losing direction
“We are building fast, but I cannot tell if we are going in the right direction.”
Scaling risk
“We need to scale and I don’t know if the architecture will hold.”
Non-technical decisions
“I am non-technical and I need to make decisions about a team or a provider.”
Independent technical review
“We need an independent technical opinion on what we are building.”
Hidden tech debt
“I don’t know if the product is accumulating tech debt.”
Rewrite or continue?
“Should we keep building on what we have or start over?”

Public sector
Architecture while requirements were still moving
400K+ entities, 9M+ API calls/hour at peak. Requirements still forming while the architecture needed to proceed. Optimizing Redis to relieve database pressure and building a roadmap toward modular architecture.
